Best Professional Flat Iron Buying Guide

Knowing Your Hair Type Is Essential To Picking the Right Flat Iron

It’s fairly surprising how many people only guess at the type of hair they have. If this is the case with you, then you should definitely make it a point to figure out what type of hair type you have. The reason for this is because it will help you greatly when it comes to matching the right hair styling tools to your specific type of hair.

This holds true when picking out a flat iron to straighten your hair with too.

In case you are wondering, there are three factors that go into figuring out what type of hair you have. These are the density of the hair follicles on your head, the thickness of each individual strand of hair on your head and the shape of the hair on your head.

Knowing Your Hair Type Is Essential To Picking the Right Flat Iron

Let’s look at each of these hair type determining factors individually.

  1. Hair density
    This refers to the closeness of the hair follicles on your head. Hair density can be described as being thin, thick or medium. The density of your hair is pretty easy to tell just by looking at your hair in the mirror. Here is how you determine the density of your hair by doing that.Start by grabbing about a fistful size clump of hair towards the front of your scalp. Gently pull it so it’s taught. Once this is done look at the base of this taught clump of hair towards your scalp. If you can see a lot scalp, your hair is said to be thin, seeing a small amount of scalp means your hair medium density and if you barely see any scalp your hair can best be described as being thick.
  2. Hair diameter (strand width)
    This is the hardest factor to determine when trying to figure out what type of hair you have. That is because it is the least visible. It’s among the most important factors in hair straightening so you need to get it right. The best way to determine your hair diameter of course is to put it under a microscope and examine it but that’s not practical for most of you.Hair diameter is described by terms such as fine, coarse and normal. So how then do you determine the strand width of your hair? Here is a pretty simple way to do that. Start by removing a single strand of hair from your head. Once that is done place it between your thumb and index finger. After you have done that grab the hair strand with your other hand and pull it straight up and out of your other hands pincer grip on it.If when the hair strand is pulled out it comes out with little resistance and you can barely feel it, then your hair is said to be fine. If the pulled strand has a slight resistance when pulled and a slight feel when doing it your hair diameter will be described as being normal. A very pronounced feeling and a harder tug is needed to pull the hair out of your pincer grip means you most likely have coarse hair.
  3. Hair Shape
    Hair can be several different combinations of shapeYour hair shape is easy to tell just by looking in the mirror. It will either appear to be straight or have some type of curl to it. If your hair strands have a sort of s-shape to them your hair will be described as being wavy. Tighter spirals in your hair will mean that your hair is best described as being curly. Hair that is course and very tightly curled (springy too) can be described as being ‘kinky’.Why is it important to know your hair shape when picking out a flat iron for yourself? That is because as a general rule the more curl you have in your hair the more heat you will need to straighten it (more on this in the buying guide).

Hair can be several different combinations of shape, diameter, and density.

It’s important to note that your hair type can be a combination of several different factors. There also is no rhyme or reason to what type of hair you have. For instance, you can have coarse hair that is thin or fine hair that is thick. So you have to look at all aspects of your hair type in order to determine what type of flat iron will straighten it the best.

Now that you know how to determine your hair type you can better match a flat iron to your needs by using the following buying guide.

What to Look For When Shopping For a New Flat Iron to Straighten Your Hair

Here is a handy buyers guide of what most professional stylists believe are the main features to focus on when shopping for a new flat iron:

  • Heat Versatility
    Different types of hair require different temperatures in order to straighten it safely. Safely is a key word here because too much heat can damage any type of hair if you are not careful. This is especially true for delicate fine or thin hair.
    Here are some recommendations as far as matching your new straightening iron to your hair type:

    1. Fine hair/Thin hair/Straight hair
      Many people feel they are cursed because they have very delicate or thin hair. It can actually be both a curse and a blessing when it comes to straightening it. Fine and thin hair types are easier to damage with heat but they can also be styled and straightened at a much lower heat setting too.Another thing worth noting is fine hair is usually not as wavy or curly as other types of hair. So why does it seem likes it needs to be straightened? That is because there is no such thing as naturally straight hair. Any strand of hair you look at under a microscope will have at least a small bend to it at the end of the strand furthest from the root. So don’t look at a person who has fine straight or thin straight hair like they are crazy if they tell you that they need to straighten it. It’s absolutely true.You have to be very careful with thin or fine hair when you go to straighten it. That is because it tends to lose its moisture and get damaged easier than other types of hair. We highly recommend if you want to straighten your thin or fine hair that you have a flat iron with lower temperature ranges.That means that your flat iron for straightening fine hair should have at least one temperature setting that is 300ºF or less. Preferably one in the 250ºF range if you have that option. Be very careful when you straighten fine or thin hair because as we said it can be so easily damaged.Be conservative when you use your flat iron. Start out on the very lowest heat setting it has at first. If that one does not straighten your hair go up one heat setting at a time until it does. Find a heat setting on your flat iron that straightens your hair nicely and does not damage it.The right heat setting for straightening your thin or fine hair should not leave it frizzy, dry or leave a bunch of split ends. With the right flat iron, there is absolutely no reason you can’t straighten your hair without damaging it.
    2. Medium hair/Normal hair/Wavy hair
      Hair that is classified as being medium, normal or wavy is kind of a double-edged sword as far as straightening it goes. On one hand, it’s not as delicate as fine or thin hair but you still have to be careful when applying high heat to it. It’s also not as hard to straighten as thick, coarse or curly hair but it still takes a good amount of heat to do it.So what kind of flat iron should you look for to straighten your medium, normal or wavy hair? The answer to that would be one that has a good variety of medium heat settings. That means it must have heat settings between 300ºF – 400ºF. This is a good heat range to break the protein bonds in medium, normal or wavy hair.Just like with fine or thin hair you don’t want to start out at the high end of the recommended temperature range. Be safe and start out at the bottom temperature range instead
    3. Coarse hair/Thick hair/Curly hair/Kinky hair
      Coarse, curly and thick hair is by far the toughest type of hair to straighten. This is especially true if you have kinky thick hair or course thick hair. That is because these types of hair have extremely strong keratin protein bonds that must be broken before these types of hair can be straightened.What is the best way to break strong keratin bonds in coarse, curly and thick hair? If you guessed with high heat you would be right. You will typically need to use flat iron temperatures in excess of 350ºF to straighten thick, curly and coarse hair.Here is a strong cautionary statement for you. Don’t automatically assume that you need the highest heat setting on a flat iron to straighten black hair. Even though thick, curly and coarse hair is harder to damage with heat than thin or fine hair, it can still be damaged by excessive heat.That’s why it’s best to start out at a heat setting of around 350ºF and work your way up in small increments. Do this until you find a heat setting that straightens your hair nicely and does not leave it damaged in the process.Check out the top rated flat irons for curly hair here!
  • Heat plate coatings and infusions
    You will be hard-pressed to find a flat iron heat plate that does not have some type of special coating or is crystal infused these days. There are several different types of coatings and infusions that you may find on straightening iron heat plates. Some of these have similar advantages they give to you when using your flat iron and yet others have totally unique properties. Read more: Ceramic VS Titanium
    Here are the major heat plate infusions and coatings and the advantages they offer to individual users or professional stylists when using a flat iron model that has them:

    1. Ceramic
      This is by far the most common type of heat plate coating. That is because it works great and it does not add a great deal of extra cost to any flat iron that has it.
      Ceramic coated heat plates give you three main advantages when they are applied to flat iron heat plates.The first is they are known to heat very evenly so the flat iron heat plates that have this coating do not form damaging hot spots. They also allow your hair to flow across the plates without catching on them and tugging your hair. Ceramic coated heat plates also help make it easier to keep your flat iron heat plates clean and residue free.
    2. Ionic/Tourmaline Crystal Infusion
      One of the biggest problems many people encounter when straightening their hair is static buildup. These flyaway hairs can make even the neatest straightening job still look bad.
      Ionic/Tourmaline crystal infusion helps you avoid this by keeping the charged ions in your hair in a neutral state. This not only prevents static it helps with shine and moisture retention too. Flatirons that have Ionic/Tourmaline crystal infusion will help eliminate frizz and split ends also.
    3. Nano Crystal Infusion
      Think of Nanocrystal infusion as regular ionic or tourmaline infusion on steroids. Experts believe that will help your hair retain up to 75% more moisture that any other type of crystal flat iron heat plate infusion. Nano Crystal Infusion will also help give your just straightened hair more shine and will also help keep it static and frizz free.
    4. Titanium
      If you like your flat iron to heat fast and heat evenly then look for one with titanium coated heat plates. Often times a flat iron that has plates coated with this material is ready to use in just a matter of seconds.
    5. Silver
      Flat iron heat plates that are coated with silver crystals benefit you in much the same way as titanium heat plate coatings do. These flat iron plates that are coated with silver crystals tend to heat up fast and heat very evenly without damaging hotspots too. Silver also has some antibacterial properties too which will help prevent unwanted organic buildup on your hair.
    6. Silicone
      When your hair strands get caught on a heat plate as you are straightening them one of two things will usually happen. It will leave a slight kink in your hair or it can possibly be damaged by over-drying it. Of course, neither of these things are good for your hair.
      There are few better lubricants known to man than silicone. That is why a flat iron heat plate that has some sort of silicone coating on it will go a long way toward keeping your hair from catching as you straighten it.
    7. Teflon
      Teflon is another form of super-lubricant that is often applied to the heat plates on flat irons. Like silicone does, this lubricant will make sure your hair flows smoothly across the heat plates during the hair straightening process.
  • Flat iron width
    Flat iron widthThe width of the flat iron you use is also very important. It should be matched to your hair length and the amount of wave or curl in it. Here is a quick guideline:

    1. Smaller than 1” width plates
      These width heat plates work best on shorter hairstyles. They also are preferred by those stylists that like to curl hair with a flat iron too. Read more about flat irons for short hairstyles here!
    2. 1” flat iron plates
      This is a good versatile straightening iron choice for just about anyone. So consider it a safe pick if you are unsure what heat plate width you want on a flat iron you are about to purchase.
    3. Larger than 1” size plates
      These larger plates work best if you have a longer hairstyle. They also are preferred if your long hair has a lot of curl in it. The larger surface area they have heats a bigger section of hair as it’s straightened.
  • Far-infrared heating
    This type of heating is a big bonus for any flat iron to have. That is because it is the gentlest form of straightening iron heat generation. Far-infrared heat is gentle on hair because it tends to heat the follicles from the inside out which means they are less susceptible to damage from being over dried.
  • Vented wet flat irons
    There are very few flat irons that are recommended for use on wet hair. That’s because straightening iron heat plates will evaporate water molecules in your hair very fast and at the same time super-heat them. The result is steam that can be very damaging to your hair. Vented wet flat irons don’t have that problem because the hot steam can escape before it over dries and damages your hair.
  • Heat up time
    Are you the type of person that is constantly in a hurry to get ready in the morning but still likes to go out with nice straight hair? Then you will definitely want a flat iron model that heats up very quickly. The fastest heating flat irons usually have titanium, silver or gold infused coatings. Most ceramic coated flat iron heat plates also will get hot very quickly.
  • Safety
    Whenever you are working with a product that often times heats up in excess of 400ºF you better make sure it’s very safe to use. Manufacturers have several ways they go about making flat irons safe to use. Look for features such as auto-shutoff timers, stay cool plastics and limited exposure heat plates that will help keep you safe when using any flat iron.
  • Ease of use
    There are certain qualities a flat iron has that make it very easy to use. This can really make any hair straightening process less tedious. Look for features such as turbo heat boost, ergonomically designs, digital temperature selection and long power cords with swivel ends that make any flat iron much simpler to use.
  • Dual voltage capability
    Do you travel often to different countries and like to have the use of your straightening iron no matter where you are? Then you definitely will want a dual voltage flat iron. A dual voltage straightening iron has the ability to be used with 115V and 230V electricity without damaging. That means you can use it in just about any country in the world.
  • Warranty
    Since you are probably looking to buy a more sophisticated model flat iron if you are a salon professional, which means you will most likely pay more for that straightening iron too. In that case, you will certainly want a good warranty to come with your flat iron purchase. Look for a warranty that is as comprehensive as possible and covers your flat iron for a long period of time.

What Kind Of Flat Irons Do Professionals Use?

What Kind Of Flat Irons Do Professionals UseThis is a hard question to answer. Some professional stylists are so good at what they do they can adapt to using any type of flat iron and make it work. With that being said, there are a few things that are ultra-important for most hair stylists to have built into their straightening irons.

Most every hair stylist will look for three major things when picking out a flat iron that they feel will help them straighten hair more easily and do so without damaging their clients’ hair. These include a wide variety of heat settings, heat plates that are nicely coated or have crystal infusion and a flat iron that is easy to use (ergonomically designed, long cord with swivel end and digitally selected operation and readout).

What Is The Most Efficient Way To Use A Hair Straightener?

Like with any hair styling task you undertake, there is a right and a wrong way to straighten hair with a flat iron. Doing it the right way will get you the optimum results.

Here is the recommended step by step process when using a flat iron:

Best Way To Use A Hair Straightener?

  • Pick the right flat iron for your hair type -We have talked a lot about how to go about doing that in this article. You need a flat iron with the right mix of temperature settings, heat plate coatings and other features that match that straightening iron well to your hair type.
  • Prep your hair properly before using your flat iron on it -This is often the most overlooked step when someone goes to straighten their hair. Don’t you make the mistake of overlooking it too? That’s because it’s too critical a step in getting your hair to straighten properly.Make sure your hair is shampooed so it’s free of contaminants and other particles that can hinder the hair straightening process. Use of a leave-in conditioner that is compatible with hair straightening irons is never a bad idea either. This can be done the night before so conditioners have a chance to work before the straightening process begins.After your hair has been shampooed make sure its dry. Using a straight iron on wet hair will damage it in most cases. Your hair should be at least 85%-90% dry before using a flat iron on it. Comb or brush your hair thoroughly. This will help get out any tangles or other rough spots that may make the straightening process more difficult.Use heat protective products on your hair. Argon and other oils will help prevent damage to your hair when using super-heated flat irons on it as will some professional hair serums.
  • Layer your hair -This is the easiest way to go about straightening your hair. Depending on the length of your hair separate the top back and sides into layers and clip it into place. This will make your hair easier to work with when using a flat iron on it and keep the straightening process uniform too.
  • Recommended best temperatures for straightening each hair type – We recommend the following heat settings for each hair type. Start at the lowest heat setting in the range and work your way up to a temperature that straightens your hair well without leaving it dry and damaged.
    1. Fine hair/Thin hair/Straight hair –
      Use a temperature setting that is in the 200ºF-300ºF if you have that option.
    2. Medium hair/Normal hair/Wavy hair –
      Heat settings between 300ºF – 400ºF work well on these types of hair.
    3. Coarse hair/Thick hair/Curly hair/Kinky hair – You will most likely need flat iron temperatures in the 350ºF-450ºF range to straighten these types of hair.As we mentioned, never automatically start at the highest heat setting on your flat iron.
      Make sure your flat iron is at the desired temperature before starting to use it too. There is a ready light or digital temp reading on many straightening irons that will indicate this.
    4. Start by using your flat iron on one layer of hair at a time – Use long smooth strokes that start as close to the root as possible. Make sure you do not go over the same spot too many times. You also don’t want to straighten too wide a section of hair at once. Straightening a few inches width of hairs at the same time usually works best.
    5. Don’t Clamp down on your hair too firmly -Let the flat iron do the work for you. That means you want your hair strands to make good contact with the heat plates but you don’t want to clamp down so firmly your hair does not easily slide along the flat iron’s heated surface.
  • Move on to the next clipped section – Once you are finished straightening one section of your hair then unclip another and straighten it next. Over time you will establish both the flat iron stroke and straightening pattern that works best for you.

5 Must-Read Tips for Keeping Your Hair Straight After Using a Flat Iron on It

Ok so now your hair is straight but how do you keep it that way. That’s the million dollar question. Here are some things that you can try that may help you accomplish this.

  1. Follow our hair preparation advice –
    The steps we have discussed about prepping your hair before straightening will also help it stay straight longer. This is yet another reason not to avoid prepping your hair properly before attempting to use a flat iron on it.
  2. Cool your hair –
    Just like high heat breaks your hair’s strong keratin bonds so does cooling it help reset these bonds in place. The best way to do this is to gently blow-dry your hair on a non-heat setting right after you have used your flat iron on it.
  3. Use hairspray –
    This is another good way to set your hair in place after you have straightened it. A word of caution here though. Don’t use a super-heavy hairspray that will make your hair look plastic and weigh it down. A light application of a medium hold hairspray should do the trick.
  4. Keep moisture away from you –
    Keratin bonds are also broken down by moisture so stay away from it at all costs. Make sure you have an umbrella if it’s raining or misting and don’t go near any situations where your hair may come into contact with released steam.
  5. Use a dry shampoo –
    This will further help eliminate any moisture buildup on the outside of your hair. Remember moisture is not your hair’s friend after you have taken the time to straighten it.

How Can You Straighten Your Hair Without Damaging It?

Best Professional Flat Iron

When you are working with a flat iron at temperatures sometimes well over 300ºF it can very easily damage and over dry your hair. Yet these high temperatures are exactly what are needed to straighten your hair. It’s kind of a catch 22 situation, to say the least. Fortunately, there are a few things you can do to accomplish straightening your hair without damaging it.

Here are a few suggestions:

  • Treat your hair with a hair oil or serum before straightening it. This will help protect it and keep it moist as you straighten your hair.
  • Use a flat iron with coated or crystal infused heat plates to help protect it during the straightening process.
  • Set the temperature on your flat iron to match your hair type. Follow the advice we gave you in the buying guide as far as matching flat iron temperature to your hair type.
  • Make sure your hair is almost completely dry before using a flat iron on it. If not you will produce super-heated steam that can damage your hair very quickly.
  • Don’t make too many passes over the same strands of hair. Remember each pass you make with a flat iron applies a lot of heat to your hair strands.
  • If you follow these simple rules it will go a long way toward preventing damage to your hair when you are straightening it with a flat iron.

10 of the Most Common Flat Iron User Mistakes

Professional Flat Iron ReviewsAsk any professional stylist and they will tell you there are some things you should never do when straightening your hair with a flat iron.
Here are some of the most common straightening iron mistakes:

  1. Blow drying your hair immediately before using a flat iron on it. This is too much heat for your hair to take in succession.
  2. Straightening your hair every day. Give your hair a break once in a while so it recovers and repairs itself naturally.
  3. Pulling your hair straight down when straightening it. For best results start close to the root when using your flat iron and pull up and out as you do each stroke.
  4. Going over the same strands of hair too many times. This is a good way to damage your hair if you are not careful.
  5. Being overly safe with your temperature setting. Sometimes having your heat too low to prevent damage to your hair will mean you are not using your flat iron at an effective temperature.
  6. Trying to straighten already damaged hairs. If you do this you will probably only damage your hair more.
  7. Using a flat iron on wet hair. Your hair will not slide across the heat plates easily like it’s supposed to and it can also be damaged easier.
  8. Not placing enough emphasis on having a quality flat iron to use. Flat irons with multiple heat settings and heat plate coatings will help you to straighten your hair easily and without damaging it.
  9. Doing your straightening passes too fast with your flat iron. Your straightening iron will lose heat each pass you make with it so working slower maintains its set temperature better.
  10. Straightening your hair after a color treatment. Color treatments tend to weaken your hair so following this up with high heat from a flat iron can severely damage your hair.

How to Clean Your Flat Iron?

One of the easiest ways to get poor results when you’re straightening your hair with a flat iron is to use it when the heat plates are dirty. This will cause your hair to get caught on the flat iron surface more often than it should and some of the residues on the flat iron heat plates may even end up in your hair when the flat iron heats up. Fortunately, these heated hair straightening devices are very easy to clean.

First of all, NEVER try to clean your flat iron when it’s still hot or when it’s still plugged in. You could get burned or severely injured if you do this.

Once your flat iron is unplugged and it’s cooled down clean it like this. Dip a cotton ball or soft cloth into some rubbing alcohol. Once you have some rubbing alcohol on the cotton ball or soft cloth then gently apply it to the heat plate surface. Use a little pressure where it’s necessary to get all of the residue off of the heat plate. This should make the surface of your flat iron heat plates look like new.

  1. Question: Should I look for a flat iron with the highest temperature setting possible to straighten my hair.
    Answer: We have mentioned many times in this article that using too high a heat when straightening your hair with a flat iron can damage it. To keep your hair safe when using a flat iron start at a lower temperature and adjust the setting up as necessary. Stop when you get to a setting that is effective for straightening your hair but does not dry it out or do other damage to it.
  2. Question: I was told by a friend you can do other things with a flat iron to your hair then just straightening it.
    Answer: This is absolutely true but you better know what you are doing. Many professional stylists use flat irons to do such things as curl hair too. They actually do a nice job of it.
    You can also make different style waves in your hair with a flat iron too. If you have a vented model flat iron you can use it to dry your hair also.
