Flat Iron Buying Guide for Fine Hair

What Is Fine/thin Hairs?

Fine Hair

The fineness of hairs refers to the “thickness” of each hair strands. Hairs that have smaller diameter and circumference are known as fine/thin hair strands. Here we are also referring these types of hairs as “thin” because each strand of fine hair is lightweight and extremely prone to breakage and therefore, needs to be handled and styled with much care and precision.

Different Types of Fine/Thin Hairs

Fine hair is not only “Fine Hair”, there are different sub-categories of this hair types and in this part, we will not only describe different types of fine/thin hairs but will also discuss the temperature range of a flat iron that should be used on these fine hairs in order to straighten them successfully. We are only discussing temperature because the other features of a flat iron manufactured for fine hairs don’t differ drastically along with the types of fine hairs.

Type of Fine/thin HairsDifferent Temperature Settings
Fine curly (natural, 4A, 4B, 4C) hairUse high temperature; select at least 350°F of heat
Fine straight hairUse any temperature settings between 200°F to 320°F
Fine fragile and damaged hairUse a temperature setting that is less than 200°F

How to Choose the Best Flat Iron for Fine/thin Hairs?

Selecting and buying the best flat iron for your fine/thin tresses is not a big deal if you know what features and aspects you should look for while buying your hair straightener. In this part, we will discuss some prominent features of flat iron that you must keep in mind when shopping for the ultimate straightening tool for your delicate fine/thin hair locks.

Moreover, aside from helping you to choose the best flat iron for your fine/thin hairs, we will also assist you to solve the problems that you usually face while straightening your fine tresses.

How to Fight Frizziness in Fine/Thin Hair with your Flat Iron

Frizzy Fine Hair

Problem

The most common problem that people with fine/thin hair suffers from is frizz, flyaways, and lack of moisture; frizzy hairs don’t align with the rest of the tresses and tend to stand up or curls independently making your hairs look really messy. Furthermore, while you try to straighten your frizzy hairs with a flat iron, the heat from the ironing tool can stripe off more moisture from the tresses resulting in even more frizzy and breakable hair strands.

Solution

If you want to control frizz while straightening your hair, then you must use a flat iron that adopts the revolutionary ionic technology to style your fine tresses.

The ionic technology features a built-in ionic generator inside the iron machine that releases an abundance of negative ions to each hair strands to establish a balance between the positive and negative ions of the hairs to make them silky, smooth and most importantly, frizz-free. Ionic technology does this by locking in hairs’ moisture and nourishment as moisture is an important factor in controlling frizz and flyaways.

Ionic technology is also known to protect hairs from high heat and heat burns.

One important information you should know is that ionic technology is also known as anti-frizz or anti-static technology, and if you ever come across these words in your flat iron, do not panic as all these names refer to the same mechanism.

To add more, often flat irons adopt other technologies alongside ionic technology to add more value to the tool, but not the technologies adopted in the flat iron are good for fine hairs, except for infrared emission. The heat energy from infrared emission penetrates each hair shaft to straighten the tresses evenly while reducing the styling time. A quicker straightening session means the delicate fine tresses are exposed to heat for less amount of time.

How to Diminish the Heat Sensitivity of Fine/thin Hairs With a Flat Iron?

Fine Hair Heating With Flat Iron

Problem

By nature, fine hairs are extremely delicate and super sensitive to heat and damage. A relatively high amount of heat from your hair straightener can burn and harm your precious hair locks beyond repair. Moreover, high heat can also make your fine hairs frizzy and static.

Solution

Now, there are quite a few aspects of flat irons that can actually work wonders on heat prone fine hairs; you just need to know them in order to straighten your tresses safely.

First of all, choose a flat iron that has pure ceramic, ceramic tourmaline, porcelain ceramic or Nano ceramic constructed and coated plates because these plates heat up evenly with a very gentle amount of heat that styles fine hairs precisely without exposing them to any burns or heat damage.

Moreover, ceramic plates are extremely lightweight and hence, help to keep the overall weight of the iron buoyant.

The temperature settings of a hair straightening iron also play a major part in keeping your fine hairs protected from heat damage and burns.

Hair experts always advise using a low heat setting on fine/thin hairs to prevent them from “frying “while styling them. In case of a flat iron, we suggest to adopt a machine that has multiple temperature settings starting from 200° F as different types of fine hairs requires different “Low” temperature (which we have discussed in details above)to straighten them properly.

How to Deal With the Lack of Volume Issue (Often Straighten Hairs Looks Flat)?

Voluminous Fine Hair

Problem

Lack of volume and life is one of the major problems that people with thin/fine hair suffers from. Moreover, when you use a flat iron to straighten your fine tresses, they become more volume less and look extremely flat on the head.

Solution

With a few simple tips and tricks, a flat iron can add extra volume to your otherwise limp fine hair locks, but, remember that there is no specific feature of a flat iron that would help you to boosts the volume of your manes.

Rather you have to ace some flat ironing techniques, like taking quite a small section of hairs at a time and lifting up them up towards the ceiling while using the ironing tool. You can also use a dry shampoo such as the Herbal Essences Biorenew White Grapefruit & Mosa Mint Dry Shampoo to add extra lift to the roots of your fine tresses to make them look full and voluminous.

Does the Length of Your Hairs Matter?

The length of your hair also plays a vital role in the selection process of the best flat iron for your fine/thin tresses; this is because the plate size of the straightener depends on the length of your hair. Normally, we prefer a universal 1-inch or a slightly wider 1 ¼ inch plate to straighten both short and long hair locks but in case of super long tresses, a flat iron with plates of more than 1 ¼ inch width is preferable because wide plates quicken the straightening session of super long hair locks.

What Should Be the Weight of a Flat Iron for Fine/Thin Hairs?

We always prefer lightweight styling tools and as for a straightening iron for fine hairs, we would always suggest that you chose an iron that is preferably 1 pound or less because straightening hairs might require quite some time and a heavy tool would eventually cause pain and hand fatigue when you hold it for a long period during the styling session.

Reasons We Didn’t Choose

Revlon Salon Straight Copper + Ceramic Smooth Flat Iron

Despite having a popular brand name and most of the “must have” features we look for in a straightener, we still couldn’t consider this Revlon Flat Iron as one of the best for fine/thin hairs because:

  • The plates of this iron machine are not made from pure ceramic; this Revlon tool features a copper plate that is coated with ceramic. Copper can get super-hot in seconds and, despite having a ceramic coating, might impose delicate fine hair locks to burn and damage.
  • While you turn up the heat, the outside surface of the plates also becomes hot as the plates inside which makes it extremely dangerous to touch the tool with bare hands.

Mangee Tourmaline Ceramic Flat Iron

This Mangee flat iron tool also possesses maximum features that we desire to have in a tool specialized to style fine/thin hairs. But we didn’t include this straightener in our “Best” list as:

  • This flat iron doesn’t come with an Ionic Technology to protect delicate fine hair locks against heat damage. Instead, it has a PTC Heating Technology that has high heat adaptivity and can get the plates extremely hot within seconds of turning on the machine which has the potential to burn fine/thin hairs beyond repair.
  • The power button, as well as the temperature control buttons, is not conveniently placed; you might accidentally turn off or increase or decrease the temperature during your styling session without even realizing.
  • Moreover, because of its temperature range, this Mangee Flat Iron is not at all suitable to be used on damaged/fragile fine hair locks.

Rusk Engineering Heat Freak Professional Ceramic & Tourmaline Straight Iron

Rusk Engineering Heat Freak Professional Ceramic & Tourmaline Straight Iron

Ranking Position: 1
Our Opinion: the Professional Flat Iron

Not only for its popular brand name but because of several legit reasons, we have chosen this RUSK flat iron as our Top Favorite straightening tool to be used on delicate fine/thin hairs. And below, we have discussed in detail about all the positive aspects of this straightener tool so that you have a clear understanding of our logic behind making this our Top choice to straighten fine tresses.

Moreover, being true to its “Heat Freak” name, the tourmaline ceramic plates of this RUSK Straight Iron heats up super quickly with a moderate amount of heat that is not at all harsh and damaging to fine tresses. Additionally, these plates distribute uniform heat throughout the strands so that your delicate tresses don’t suffer from any hot spots and breakage.

Even though RUSK didn’t include an LCD screen to this straightener, the temperature control, and monitoring is quite easy because of the rheostat dial button incorporated into the handle of the tool; this rheostat dial is marked with different temperature levels, like 250° F and 345° F, so that you don’t find it difficult to set your required heat during your styling session. And as the heat setting starts from as low as 235° F, you have the opportunity to choose a very low heat level to put on your fine hairs and stopping them from any heat burns and damage.

Bio Ionic Onepass Straightening Iron

Bio Ionic Onepass Straightening Iron

Ranking Position: 2
Our Opinion: Straightens in Just One Pass

BIO IONIC is one renowned brand that manufactures different amazing professional grade hair tools to style your luscious hair locks flawlessly, and its OnePass Straightening Iron is no different; it has more than a few incredible features that can provide outstanding straightening results in fine hair locks. But as this flat iron doesn’t have a plate size suitable for super long hairs (plate of more than 1-inch width) and is quite expensive, it didn’t end up grabbing the top place in our “Best” list.

Aside from this very minor gripe, the features that made this Onepass straightener our second best pick are:

As the name suggests, this flat iron straighten a portion of your hairs just with one pass of the tool; the volcanic minerals infused ceramic plates of this straightening iron are adorned with patented Silicone Speed Strips that grip hair perfectly and provide enough natural tension so that the user doesn’t have to go through the same portion of hair twice or more times.

Furthermore, as hairs are styled in just one pass of the machine, these silicon strips combined with the infrared emission ensure a faster styling process with an increased shine of your tresses.

To add more, these volcanic minerals infused ceramic cushion plates of this OnePass flat iron along with the ionic technology emit plenty of negative ions to the tresses that help to break down the water clusters of the fine hairs easily; the micronized water molecules then penetrate each hair strands for extreme hydration and nourishment to make your frizzy fine tresses glossy, silky and incredibly smooth.

The BioCeramic™ Heaters incorporated in this straightener heat up the cushion plates in just 5 Seconds so that the users don’t have to wait for a long time before starting their straightening session.

Moreover, as this tool comes with multiple temperature settings, BIO IONIC added a temperature control knob button that is labeled with different heat setting, starting from 240° F, for the users to select their desired temperature level extremely easily.

Additionally, as it comes with versatile heat levels, you can use this flat iron to straighten every type of fine/thin hair locks that we have discussed previously.

  • Comes with a red indicator light for additional safety of the users
  • The iron is compact and lightweight and can be carried around easily
  • The 9 Ft long swivel cord provides freedom of movement to the users
  • BIO IONIC provides a 5 Year Warranty period to ensure the longevity of the machine

Babyliss Pro Porcelain Ceramic Straightening Iron

Babyliss Pro Porcelain Ceramic Straightening Iron

Ranking Position: 3
Our Opinion: a Budget-friendly Choice

If you are not willing to spend a “moolah” on a single hair styling tool but still want to have the best quality straightening iron, then this Porcelain Ceramic flat iron from BaByliss PRO would make a great choice for you, and that’s why we have suggested this straightening tool as a close alternative of the BIO IONIC Onepass Straightening Iron at a very affordable price tag.

Unlike the OnePass iron, the plates of this BaByliss straightener are constructed using porcelain ceramic which not only assures exceptional heat distribution throughout the hairs but also releases more ions (in combination with the ionic technology) and infrared energy to the tresses compared to any standard ceramic constructed plates to make them frizz-free, silky and smooth.

Porcelain ceramic plates also produce a very moderate amount of heat that straightens fine hairs promptly but is gentle enough to not burn or damage the tresses.

Moreover, the Ceramic heater of this flat iron machine ensures instant heat-up of the plates and super quick recovery so that the plates don’t lose heat and remain hot for as long as the machine is on which would speed up your styling process.

Additionally, the relatively longer plates of this styler allow the users to work faster with wider sections of hairs reducing straightening time even more.

Another amazing feature of this Babyliss flat iron is its temperature settings; Babyliss made sure that you can choose a heat as low as 240° F so that there is little chance of exposing your super delicate fine tresses to unnecessary heat which might lead to un-repairable damage. Moreover, such low heat setting is also suitable for all types of fine hairs and can straighten them quite smoothly without frying them.

To add more, BaByliss PRO offers 3 different sizes of this straightening iron to its customers, unlike the BIO IONIC one, so that people with every hair length (short, medium, long and extra-long)finds the perfect plate size that is suitable to straighten their fine hairs flawlessly.

Few Additional Features

  • Comes with a labeled rheostat dial for effortless temperature control
  • Porcelain ceramic plates glide through hairs super smoothly without creating any mess
  • The controls and on/off switches are placed at the end of the handle for extra convenience
  • BaByliss added a detailed user manual to provide all the necessary information
  • Comes with an 8-ft long cord with swivel ends for tangle-free use
  • This straightening iron is backed up by 3 Years Limited Warranty Period

CHI Fire Red Tourmaline Ceramic Flat Iron

CHI Fire Red Tourmaline Ceramic Flat Iron - V1 Mar

Ranking Position: 4
Our Opinion: a Colorful Flat Iron to Adorn Your Vanity

This CHI AIR Expert is yet another of our favorite flat iron that offers more than a few outstanding features to straighten fine tresses smoothly to the perfection.

Even after having such outstanding features, this straightening iron didn’t score the top position, not because of its expensive price tag, but because of its comparatively heavyweight; at 1.3 pounds, this AIR Expert classic is quite heavy in weight in comparison to our top choices and might cause pain to the users hand if they use it for a long time.

Other than this minor gripe, this CHI Air Expert Classic flat iron is “a piece of cake” to use on fine hairs. This is because:

This professional grade flat iron comes with plates that are constructed with ceramic tourmaline to provide its users with the best benefits of both these materials; the ceramic tourmaline plates heat up with gentle temperature and distribute heat evenly throughout the hair strands to straighten them super precisely without any damage or hot spots. These plates make sure that your delicate fine hairs remain healthy throughout the styling process.

Moreover, the plates of this straightening iron have floating features which mean that the plates move in the direction you pull the tool to have flex and reach as near as possible to the hair strands.

The advantage of floating plates is that these plates help to reduce breakage, snagging or kinks in your fine hairs while you straighten them and result in crinkle-free straightened locks.

In addition to the ceramic tourmaline floating plates, this Classis flat iron also incorporates a built-in ionic generator that disperses abundance of negative ions to protect your fine hairs from heat damage even further.

The ionic technology also actively reduces frizz and statics from your frizz-prone fine hairs by locking in hairs moisture and nourishment so that you can enjoy silky, flowy straightened hairs all day long.

The infrared emission mechanism of this tool also plays a major part in straightening your gentle fine hairs quickly and without heat damage; the energy from infrared emission penetrates fine hair strands and straightens them from inside out so that the styling process is quick and your super damage-prone fine tresses are less exposed to heat.

The multiple different temperature setting is also a notable feature of this straightening iron. You can choose a heat level from as low as 180° F and then increase it according to your fine hair type and your heat preference. The plates also heat up in just 30 seconds with your selected temperature reducing your waiting time before the styling.

Few Additional Features

  • This straightener comes with a thermal mat for safety purpose and ease of usage
  • The LED indicator light ensures the safety of the users by signaling when the tool is ON
  • Incorporates 60 minutes auto shutoff feature for extra safety of the users
  • The conveniently placed controls and switches make using the tool very easy
  • CHI offers a huge color range for this flat iron to choose from
  • Comes with a 9 feet long, tangle-free swivel cord for ease of use and ease of storage
  • The dual voltage feature made this straightener a true international flat iron
  • CHI provides a 1 Years Limited Warranty period for this tool to ensure its durability

How to Prepare Your Fine/thin Hairs for Flat Ironing?

Fine hairs are super delicate and therefore, they need special care and attention before you apply heat to them for straightening purpose, otherwise, there is an extreme possibility that your hairs might get burnt.

Here’s how to prepare your fine hair locks for flat ironing:

Step 1

Wash and condition your tresses thoroughly with products specifically formulated for fine hairs to create a smooth base to glide your straightening iron effortlessly. The Luxurious Volume Full Splendor Shampoo by John Frieda and Living Proof Full Conditioner might be a great choice to use on your fine manes.

Step 2

Towel dry your hair thoroughly with a microfiber towel as the microfiber towel absorbs water quickly making the drying process faster. You might try this DuraComfort Essentials Super Absorbent Anti-Frizz Microfiber Hair Towel that doesn’t only dry your tresses but also helps to control the frizz of your fine hairs.

Step 3

Once you are done with towel drying you hairs, comb your hair with a wide-toothed comb so that there are no tangles or knots left in your hair locks. Now blow dry your hairs with a premium quality hair dry, like this Conair 1875 Watt Ionic Ceramic Hair Dryer, as using a flat iron on wet hairs is totally forbidden; a flat iron would cause damage and breakage if you use it on your wet fine tresses.

Step 4

Last but not the least, apply a heat protectant spray or serum to your dried hairs so that there is a barrier between your hair strands and the applied heat and your hair suffers from zero to minimal heat damage. The Kenra Thermal Styling Spray 19 is an amazing protectant that doesn’t weight down your already “volume-less” fine hair locks.

Our Final Thoughts

Fine hairs are delicate and need to be styled with extreme care. All the flat irons that we have suggested above come with specific properties that not only straighten fine hair locks with utmost perfection but at the same time also take incredible care of the tresses. Therefore, according to our opinion, you won’t be disappointed after purchasing any of these straighteners because they are guaranteed to provide the best value of your money.
