3. Why use a flat iron?

Flat irons are a great way to tame ill-behaved hair or totally change your style with just a few minutes of work. They’re especially useful for those who:

  1. Have hard-to-tame fly-away hairs, unruly curls, or wavy-but-not-quite-straight hair.
  2. Are looking for a quick way to switch up their look.
  3. Want a versatile tool that can crimp, straighten, and curl depending on their mood.

4. Flat iron plate material

The plates, and the material they are made of are the most important aspect of hair straighteners. They change the shape of your hair to make it straight, curly, or crimped, by using a combination of heat and pressure. The plates generate heat that transfers to your hair when you apply pressure to it, forcing your hair to temporarily conform to the plates’ shape. This makes your hair straight, or curly depending on the motion that you make with it.

The plates can be made from several different materials. The plate material that’s right for you depends entirely on your hair type.

  1. Ceramic irons—Ceramic irons are some of the oldest and most reliable flat irons on the market. They get hot quickly and stay hot, and they tend to last a long time. They work by generating negative ions that smooth your hair. The wonderful thing about ceramic irons is that they work for virtually all hair types. Avoid irons that are labeled as “ceramic coated”, though; ceramic coating will break down over time and cause issues with heat consistency.
  2. Tourmaline irons—Tourmaline irons are a fairly new innovation, and are usually composed of ceramic base plates coated in ground-up tourmaline (a type of stone) that can smooth hair up to six times more effectively than ceramic irons. Tourmaline irons are great at maintaining a consistent heat, and they’re also more effective at low heats than most other irons.
  3. Titanium irons—Titanium flat irons are often lauded for their ability to maintain and distribute heat evenly and their reputation for not burning hair. Titanium irons are usually more lightweight than irons made with other materials, but they don’t work well for delicate, thin, or already-straight hair.

Which iron is right for my hair type?

If you have thick, curly, or full-bodied hair, you’re in luck: ceramic, tourmaline, and titanium irons will all work wonderfully on your hair. People with medium-bodied or wavy hair can safely choose any one of the three plate options, too. If you have especially thin, fine, or straight hair, however, you’ll want to avoid titanium irons. This is because titanium irons can reach very high levels of heat, which can damage your hair, especially if your hair is thin or fine.

Regardless of your hair’s consistency, tourmaline (or tourmaline/ceramic) irons are the most reliable option on the market for smoothing hair.

5. Flat iron technologies

Flat irons are becoming more high-tech by the year. Four terms—silver, infrared, nano, and wet-to-dry—make an appearance on nearly every straightener advertisement today. What do these terms mean, and will the technologies improve your straightening experience?

  1. Silver—Plates that incorporate silver are said to eliminate germs and the buildup of unsanitary microbes on your iron. This is great for the health-conscious consumer, but a regular cleaning will accomplish essentially the same thing. Therefore, it’s not necessary for those on a tighter budget.
  2. Infrared—Infrared technology was designed to heat hair more gradually and evenly to protect hair from damage and straighten it faster.
  3. Nano—If a company uses the term “nano technology”, it means that the material used to create the plates is formed into microscopic particles to generate more of the negative ions that style your hair. This results in a smoother plate and a faster styling.
  4. Wet to dry—New technologies are emerging that claim to work on wet hair and leave you with dry, straightened hair. These types of irons work well on dry hair and can often be used effectively on damp locks, but they typically don’t work very well for straight-out-of-the-shower hair.

In a nutshell: If you’re concerned about the cleanliness of your styling tools, look for a flat iron that uses silver in the plate. Infrared technology and nano technology are both great for those with minimal time, but infrared is especially useful for those with hair prone to damage.

6. What size plate do you need?

As you shop for a flat iron, you’ll notice that the plates typically come in two sizes: narrow and wide.

  • Narrow plates (one inch in width or less) are ideal for more in-depth styling techniques like curling and crimping. They’re also better-suited to people with short to medium-length hair.
  • Wide plates (over one inch in width) are ideal for longer hair, and can straighten more hair at a time.

The wider the plate, the more quickly it can straighten your hair. However, for those with a variety of styling needs—like curling one day and smoothing the next—narrow plates will provide more versatility.

7. Finding the right temperature

Different flat irons also offer different levels of heat. The amount of heat you want depends entirely on your hair type. Generally:

  • Those with thick and curly hair will fair best with an iron capable of heating to at least 380° F (195° C).
  • Those with medium-bodied and wavy hair will do fine with irons that can heat to 360° F (180° C).
  • If your hair is especially thin, straight, or prone to damage, choose an iron that offers a heat setting under 360°F (180° C).

The hotter the iron, the quicker and more effectively it will straighten hair, but a too hot iron can damage your hair, especially if your hair is thin.

8. Available accessories

Many flat irons come with a range of tools and accessories to keep your styling sessions safe, easy, and hygienic. The tools you need will depend on your budget and lifestyle.

  1. Holders: Some irons come with a holder that mounts to a wall, sits on a surface, or attaches to the edge of a table. These holders help to make storage safer and more convenient.
  2. Carrying bags: Irons sometimes include a convenient carrying bag, which is great for those who travel often and want to keep up with their styling routine. Some bags are even heat resistant to reduce the risk of damage and fire.
  3. Heatresistant mats: These allow you to place your hot iron down without risking damage or fire.
  4. Cleaning tools: Your iron purchase might include a cleaning kit to help you keep the straighter as effective and sanitized as the day you bought it.
  5. Replacement plates: Some irons come with replacement plates to help extend the lifespan of your investment.

9. Helpful features

Flat irons usually incorporate a simple and streamlined design, but many have bonus features that improve safety or give you greater control over your straightening experience.

Auto-off features use a sensor to turn off the iron when it hasn’t been used for a set amount of time. Usually, the iron will turn off after 10, 20, or 30 minutes have gone by to prevent fires.

Temperature controls allow users to turn a dial to select an exact plate temperature or to choose between low, medium, and high settings. This is particularly useful when your hair is more or less curly from one day to the next and when you need a quick touch-up rather than a full straightening treatment.

Digital readouts allow you to monitor the iron’s exact temperature without squinting at a dial. They also make it easier to tell when the iron is hot enough to use.
