How to Flat Iron Hair

Straight hair is remarkably quick and easy to get using a flat iron styling tool in the comfort of your home. Ceramic flat irons are generally regarded as the best material that does the least amount of damage to your hair. Professional-grade ceramic irons produce negative ions and infrared heat that seal in moisture as you straighten your hair.^[1] By using the proper straightening technique and applying the appropriate hair treatments before and after straightening, you can keep your hair straight all day and protect your hair from heat damage. Follow the steps below to learn how to properly flat iron your hair from start to finish.

EditPrepping Your Hair for Heat

Use shampooing and conditioning products that are specially formulated to create straight or sleek hair. You don't need to buy expensive hair products, anything you can find at your local drug store or beauty supply store will work fine. Just look for products that claim to be straightening and/or moisturizing.

Pat your hair dry after getting out of the shower. Use your towel to remove water from your hair by gently squeezing your hair in sections rather than harshly ruffling it dry. Patting your hair dry helps prevent excess frizz from occurring after showering.

Use a thermal protection serum or heat treatment while your hair is wet. You should apply it when your hair is wet because it allows you to evenly spread the serum around your hair without creating clumps. Comb your hair with a wide-toothed comb after applying.
- Products with obliphica Berry, argon nut oil, Moroccan oil, or coconut oil are thought to help keep hair straight throughout the day. ^[2]
- Products with silicone will also help to keep your hair straight.

Blow-dry your hair. You want your hair to be as dry as possible when straightening. Not only will this allow your flat iron to work better, it will also prevent you hair from being shocked by the heat and breaking off.
- Point the hair dryer downward with the flow of your hair while blow-drying. This downward motion away from your roots encourages your hair to dry straight.
- Set your hair dryer on the lowest heat setting. If you have particularly frizzy hair, drying your hair on a lower heat setting for a longer period of time will prevent your hair from puffing up as you dry it.

EditLearning the Technique

Plug in your iron and flick the switch to "on." There will also be a numbered heat setting near the "on" switch that you can adjust to your desired heat level. The thicker and frizzier your hair, the higher the numbered setting should be. If your hair is particularly thin and brittle make sure to set your straightener to the lowest number to avoid damaging your hair.

Separate your hair into several sections. The number of sections will depend on the thickness of your hair. The key is to make sections one to two inches thick so that they can easily pass through the straightener.
- Pin or clip the sections you are not using out of the way as you straighten each individual section.
- An easy way to do this is to pin all of the sections that you are not using on the top of your head or behind your shoulders. Then take each individual section in front of your shoulder to straighten it.

Place the straightener as close to the roots of the section as possible without burning yourself. This will usually mean that your straightener will start about an inch from your scalp.

Clamp the iron down so that the heated sides touch and your hair rests between them. Be sure not to clamp too firmly, as this will create a ridge in the top of the hair section where you start straightening. Additionally, be sure not to hold the flat iron in the same spot for too long, as doing so will also cause a ridge to form in your hair.

Run the flat iron down the length of your section of hair. Your motion should be a fluid and steady sweep from the roots to the ends. The most important part of this technique is that you don't hold the straightener in any one place for too long. Doing so can damage your hair and create undesirable folds.

Run the straightener over the section several times until it is completely straight. Depending on the thickness of your hair, you may only have to do this once, or you may have to run the straightener over a section of hair several times.
- The strength of your flat iron will also determine how many times you will have to run over a particular section of hair.
- The lower the heating setting on the flat iron, the more times you will have to run your straightener over a particular section of hair.
- Don't be alarmed if you see steam rising from the flat iron. Steam occurs as a result of the hot ceramic making contact with any leftover moisture in your hair. If you start to smell burning hair, however, turn down the heat setting on the flat iron immediately.

Move the straightened piece out of the way and unclip a new section of hair. It is generally easiest to move around your head from one side to the other rather than taking random chunks so that you can easily separate the straightened chunks from the non-straightened ones. You may need to brush each section before straightening it if it got tangled while pinned.
- If your hair is prone to frizz, apply a hair spray or setting serum to each section immediately after you straighten it.
- Avoid getting any product on sections of hair that you have not straightened yet. Product can negatively interfere with the straightening process, causing damage to your hair or to your flat iron.

EditKeeping Your Hair Straight

Set your blow dryer to cold on the lowest air flow setting. Blow-dry your hair for another minute carefully to set your straightened hair. You can use a thick brush to guide your hair in a straight motion if you prefer.

Apply a hair spray, a post-straightening product, or a setting spray to keep your hair straight all day. Anti-frizz serum that contains silicone is especially effective at keeping hair straight after flat ironing.^[3]

Carry an umbrella with you. If you live in a climate prone to random bouts of moisture, carry an umbrella with you in case it starts to rain or mist heavily. External moisture will cause your hair to become frizzy again.

EditTips

Use a comb. When straightening a section, run a fine-toothed comb just half an inch below the straightener as you go down the section.

Make sure that your hair is clean, dry, and brushed before using a flat iron.

Try not to touch your hair too much; your fingers produce a lot of oils.

EditWarnings

Always turn your flat iron off after using as a safety precaution. Flat irons that are left on can either break or have the potential to start a fire.
