7 of the Best Flat Irons for Fine Hair | Buying Guide & Reviews

Last Updated:July 26, 2020

As someone who aspires to sleek hair, I’ve had my share of mishaps with a flat iron. My hair tends towards the fine side and used to lack the volume and bounce that I craved. I started searching for the best flat iron for fine hair and learned a thing or two that may surprise you.

How to Choose the Best Flat Iron

Is your hair fine or thin?

Before buying a flat iron for fine hair, you have to diagnose your hair type first. Fine hair can be straight or wavy. Caucasians typically have this kind of hair. Fine hair has thinner follicles than coarse hair. If you have fine hair, your hair strands have a smaller diameter if you look at them individually.

Fine hair may require extra care because of its fragility. It tends to break and it takes less heat to damage it. I’ve learned to keep this in mind when styling. On the bright side, you can easily flatten fine hair with less heat.

It’s also important to note that fine hair does not necessarily equate to thin hair. You can have thinner individual strands of hair yet have lots of hair. Hair density refers to how many hairs there are on your head. You may also have both thin and fine hair.

What type of flat iron is best for fine hair?

Here, we’ll determine the best flat iron for fine hair. If you were wondering if titanium or ceramic is better for your fine hair needs, read on.

Plate Material

There are several things to keep in mind when looking for the best straightener. Foremost is the type of material the plates have. These are the most important component of a flat iron because it’s the part that gets in contact with your hair the most.

Titanium is a material revered for its efficiency in straightening hair. It heats up very quickly compared to the ceramic flat iron. Titanium itself is lightweight, which is always a plus. Titanium flat irons are a staple in salons for their durability as well. For everyday use, it can save you time because it transfers heat well.

The ceramic flat iron has an edge over titanium primarily because it conducts heat evenly and retains that hotness well. It gives smooth and polished results. It’s often best for fine hair because it lessens hair damage from the heat. Remember to look for pure ceramic plates. Some flat irons are only coated with ceramic, which can chip off.

Under the ceramic category is tourmaline, a semiprecious stone that is crushed and layered on the ceramic plate. Though a bit more pricey, this material can be good to have for dry and frizzy hair because it gives off negative ions that neutralize the positive ions in damaged hair.

Plate Width

The next criterion to be aware of is your flat iron’s plate width. The ideal width depends on how long your hair is. For longer lengths, go wider than an inch. Be warned though that bigger plates can cause more damage because more hair is exposed to heat. Plates that are 1 inch and below give you more control when styling and reduce heat exposure.

Adjustable Heat Settings

Third, when styling fine hair, you’ll need a flat iron with adjustable temperature controls. To avoid scorching your hair, keep the temperature as low as possible and not more than 300F. Remember that hair combusts at the same rate as paper (451F). Steer clear of that temperature range for good measure.

Ionic Technology

The next thing to look for is ionic technology. Most modern flat irons already use this because it cuts the risk of heat damage. Negative ions penetrate the hair shaft so you get a smooth, glassy look. They also fight frizz and static and protect hair from the damaging properties of heat.

Floating or Fixed Plates

Lastly, think about whether your hair can benefit more from floating or fixed plates. Floating plates are plates that can adjust from side to side when you smooth down your hair. These allow you to compress your evenly. If your hair is on the thinner side, floating plates can be a good choice so you can clamp down your locks more easily and straighten them in one pass. Fixed plates are locked in place and are more common.

What’s the best way to use a flat iron on fine hair?

Because fine hair can be sensitive, hair prep is key. Wash and condition your hair with products appropriate to your hair type. Be wary of heavy conditioners that weigh your hair down. After washing, dry your hair gently. Squeeze out residual water with a towel.

Next, apply a heat protectant all over your hair while damp. Distribute evenly but skip the roots. Use a wide-tooth comb to untangle any knots. To ensure your hair is bone dry, use a hairdryer to get rid of any dampness that’s left. Point the nozzle downwards and pull the hair taut. Work in sections, starting from the bottom upwards.

Begin styling with a flat iron, making sure your hair is fully dry. Use clips to section your hair. I like to divide hair into one-inch parts.

Place the flat iron on the lowest setting. You can adjust this later on if you need more heat. Grab the section you are working on and thread the flat iron through the hair, as close as you can to the roots without burning yourself.

Clamp down lightly on the hair. Apply firm pressure but not too much or else your hair will crease. Smooth down the hair until your desired straightness is achieved. Side note: please, if you smell any burning, stop and lower the temperature to avoid permanently damaging the hair.

Move on to another area of hair until you’ve finished the entire head. Go through your hair with a blowdryer once again and brush it through for maximum polish. Apply a finisher such as a setting spray or hair serum to lock in the style and nourish the hair.

The 7 Best Flat Irons for Fine Hair, Reviewed

KIPOZI Professional Titanium Flat Iron

KIPOZI Professional Titanium Flat Iron
$37.06 ($37.06 / Count)

  • Precision-milled Nano titanium plates
  • Floating Plates design
  • Perfect Plate Alignment

08/15/2020 08:00 am

The KIPOZI Flat Iron has floating titanium plates that heat your hair evenly. The plates are slightly wider than ideal for fine hair, at 1.75 inches, but they get the job done quickly. The flat iron has an adjustable temperature which can get as low as 270F, perfect for fragile, fine hair. You can always see the heat level on the flat iron’s LCD display. If it gets too hot, the hair straightener thankfully has an intelligent safety temperature reduction system that brings the heat down accordingly.

Other features include a 60-minute automatic shutoff, which I always appreciate in a flat iron. There’s also an 8 feet swivel power cord. I found this convenient and more than adequate for everyday styling. There’s also a dual voltage function so you can always take this to trips abroad with no additional converters in tow.

The flat iron weighs a hefty 1.61 pounds. It’s not a dealbreaker (I have dumbbells heavier than that) but for longer styling, it can take a toll on the arms. I usually just switch from one arm to the other.

This flat iron is the best choice for those with thicker hair because the roomier plates can accommodate the extra density quite easily. This is also great for people who want a quick straightening session because titanium plates are known for efficiency and fast heat transfer.

CHI G2 Ceramic and Titanium

CHI PRO G2 Digital Titanium Infused Ceramic 1inch
$69.99

  • Titanium Infused Ceramic Plates
  • Ceramic Heaters
  • Smart Temperature Control

08/15/2020 08:00 pm

The CHI G2 Ceramic and Titanium Flat Iron is made of an elegant black shell affixed with golden plates. The plates are titanium-infused ceramic plates (I guess, so it can have the best of both worlds component-wise). The 1.25-inch plates are a good width for me, though it’s slightly wider than what’s recommended for fine hair.

The CHI Flat Iron heats up in only 40 seconds and promises to deliver silky, shiny, and frizz-free hair. It’s quite efficient, maybe because of the titanium infusion, and I liked the color-coded digital temperature settings. The display lights up with a blue hue if you select a heat level for fine hair.

Other nifty add-ons are a dual voltage feature and a 1-hour auto-shutoff. At 15.8 ounces, this is pretty light.

This flat iron would be best-suited to those who want a straightener that’s light yet efficient. The design is subdued but ergonomic. No fancy colors or features here, but if you want something utilitarian and bare bones, this is the hair straightener for you.

A disadvantage I observed with the CHI G2 flat iron is that the plates are ceramic-coated and not 100% ceramic like I initially thought they would be.

Pros

Cons

INFINITIPRO BY CONAIR 1 Inch Titanium Flat Iron

The rainbow-hued gradient plates on the Infinitipro by Conair Flat Iron are quite the charmer. If you’re a fan of unexpected colors, you’ll find this visually pleasing. The floating plates help you clamp down hair evenly for accurate straightening. These are the perfect size for fine hair at 1 inch wide.

The Infinitipro hair straightener has a 30-second heat-up, shaving off time in your routine. There are 6 heat settings to choose from and an auto-shutoff feature.

What I liked about this flat iron are the long plates that grip more hair surface at a time. Its ion-generating properties are good for smoothing away frizz from locks.

A lot of users have sung their praises about this flat iron, saying it glides like butter through the hair. If you’re someone who wants smooth hair without waiting ages, this could be the best flat iron for you.

If you have thinner hair though, it’s best to stay away because it’s difficult to hold down hair well with this. Hair can slip out of the plates if you don’t clamp down enough. The build quality can also be improved on, particularly the glossy black shell which shows marks, dirt, and sprays easily.

Pros

Cons

Remington Pro 1″ Flat Iron

Purple fans, unite! The Remington Pro is a royal-hued hair straightener that is permeated with 10 times more ceramic than the regular Remington, according to the product claims. What this means for fine hair is less damage from heat and less frizz.

The Remington boasts of a Thermaluxe advanced thermal technology that smoothens hair with longer-lasting results. For fine hair, I think a single pass is enough for glassy locks.

The hair straightener heats up in a mere 15 seconds. With 30 heat settings, there’s definitely something for any hair type. It provides consistent salon-high heat at 120V (sadly, not good for traveling). There’s a hinge lock which comes in handy for storing your flat iron safely, as well as a heat-protective pouch.

There’s an automatic shutoff feature after 1 hour and the flat iron weighs 1.5 pounds.

The great thing about the Remington is its 4-year warranty, which is double that of other brands I’ve tried. The ceramic plates skim hair well and I liked the user experience.

A few caveats: the cord is too short and is wrapped in fabric, which can stain easily. The heat settings do not indicate the temperature. Instead, they are numbered from 1 to 30. The temperature dial is placed awkwardly inside the iron and there is no digital readout, either.

Pros

Cons

ghd Platinum+ Professional Performance Hair Styler

ghd Platinum+ Professional Performance Hair Styler
$249.00

  • World's first smart flat iron
  • Predictive Technology
  • Ultra-Zone Technology

08/15/2020 08:04 am

Because of its luxury price, I was doubtful of the Platinum+ flat iron’s claims. It promised to deliver less breakage and more color protection with an ultra-predictive technology that adapts the temperature to each hair section. I was bummed to find out that it had only one temperature (365F) which reportedly is optimal for styling hair. It does not only adapt to your hair’s thickness, it also recognizes the speed of your styling.

The flat iron achieves silky results and lives up to its claims. Its 1.25-inch ceramic plates maintain heat fairly well and heat up in 20 seconds. There’s a wishbone hinge that’s good for preventing snags and a 9-feet swivel cord. Its round barrel makes this a good option for curling hair as well.

Other features include dual voltage, which is perfect for travel, and an automatic sleep mode after 30 minutes of non-use.

At 1 pound, this flat iron is light but what I love most is its elegant look. It has a slim design that is easy to hold. However, the elephant in the room is its lack of temperature controls. That’s not a good sign for us fine-haired folks. At 365F, it’s a smidge too high, and you can risk frying your hair if you’re not careful. This is more suited for those with thick hair.

Pros

Cons

RUSK Engineering Heat Freak Professional Ceramic and Tourmaline Straight Iron

The Rusk is one of the best flat irons for those who want a no-frills, no-nonsense heating tool. The 1-inch plates are made of tourmaline ceramic, a high-end material that removes frizz and prevents heat damage. I like ceramic tourmaline best for fine hair because it seals the cuticle. You can thank the negative ions it emits for that. The flat iron also gives off far-infrared heat for pin-straight hair. Overall, I found it efficient and gentle on my mane. This ceramic flat iron is easy to use because of its lightweight. I like the shiny and smooth results it gives me. I think it would be good for those who struggle with frizzy hair.

The Rusk flat iron’s main drawback is its lack of an automatic shutdown feature. It’s essential if you’re not blessed in the memory department or have days when you just rush out the door. I also think the plates don’t clamp down close enough for fine, thin hair but you can work around it with firmer pressure.

Pros

Cons

BIO IONIC 10x Pro Styling Iron, 1 Inch

The Bio Ionic flat iron has high-end features at a high-end price. It stands out from other straighteners because of its vibrating plates. It claims to smooth and style in less than 10 minutes. I found that to be true, in my experience, because the vibrations halved my styling time.

The flat iron is infused with natural rock minerals. Its ceramic plates emit negative ions to add hydration back to the hair. If you have color-treated or damaged hair, you may want to give this a try.

The flat iron also has digital temperature controls (nice to have) and dual voltage for those who’ve been bitten by the travel bug. I appreciated the 1-hour automatic shutoff and the 9 feet swivel cord, great for using hair straighteners far from electric outlets.

I found the Bio Ionic flat iron easy to hold because of its soft touch handle. It’s also comfortable to use because it’s lightweight. I was pleased by its aesthetics: understated but sleek.

The iron glides through hair and is quite efficient. This flat iron would be best for busy bees who still want groomed hair. If you like curling your hair with a flat iron, this would be a good choice. The rounded tips can create beach waves without snags.

Overall, this iron is a good all-rounder, that is if you can shell out a pretty penny.

Pros

These are the best straighteners for hair like mine: fine with a tendency towards damage. Of the above flat irons, the one that stands out the most is the Bio Ionic 10x Pro Styling Iron. The ceramic plates are gentle on sensitive locks and at 1 inch, they are the best width for straightening without damage. The flat iron has adjustable temperature settings. As its name implies, it has an ionic technology that protects the hair shaft. The vibrating plates are a bonus and it made styling quicker. The straightener was a pleasure to use and curled hair effortlessly, to boot. It’s definitely one of the best flat irons I’ve tried and it’s a no brainer for me to recommend it.
