If you love straightening your hair but can't seem to avoid the frizz that comes with it, we've been there! Naturally curly hair can be tough to tame, but it can be done. We've researched all the best tips on straightening curly hair with frizz-free results so we could share them with you. Below, we'll walk you through the entire straightening process and finish up with few tricks on how to extend the life of your straight style.

1

Wash your hair with moisturizing shampoo.

  1. Start with clean hair for smooth, frizz-free results. Use a gentle shampoo made with hydrating ingredients like glycerin, aloe vera, and coconut oil. Wet your hair with warm water, lather up, and rinse with warm water. Avoid shampoos with alcohols and sulfates since those tend to dry out hair and create frizz.[1]
    • Avoid hot water since it strips hair of its natural oils and causes frizz.
    • Your hair's natural oils can also help protect it from heat-styling damage.

Apply a strengthening treatment.

  1. A protein or bond building treatment preps your hair for heat styling. Hair straightening involves a lot of hot tools that can damage your hair. Using a strengthening treatment first can help you minimize that! Most strengthening treatments are applied like conditioner and rinsed out after several minutes. Check your product’s packaging instructions for specific details and instructions.[2]
    • Some products are leave-in and others require rinsing. Be sure to check!
    • If you don’t have a strengthening treatment, do a deep-conditioning treatment. A big dose of hydration helps prevent frizz and minimize damage.

Apply heat protectant from root to tip.

  1. Thermal protectants prevent hair damage caused by heat styling tools. If you have fine hair, use a lighter, spray-on thermal protectant that won’t weigh down your locks. If your hair is on the thicker side, go with a cream thermal protectant instead. Whatever you choose, don’t skip out on this step! Putting a barrier between your hair and damaging heat is really important.[7]

Divide your hair into 4-6 sections.

  1. Clip all the sections up and out of the way except the bottom one. Working in sections allows you to concentrate on 1 area at a time so you can get it super smooth and completely dry before moving on. Gently coil and clip each section up on top of your head with plastic hair clips. Leave the bottom section down since that’s easiest place to start blow-drying.[8]
    • The sections don’t have to be perfect!
    • If you’d like, apply a small amount of smoothing serum to each section from root to tip before you blow dry it.

Dry the first section with a medium round brush.

  1. Use a ceramic or boar bristle round brush for the smoothest results. Position the round brush under the bottom section of hair close to the roots and turn on the blow dryer. Aim the diffuser straight down at your hair and slowly roll the round brush through your hair to the ends, moving the diffuser with the brush at the same speed. Keep doing this until your hair is completely dry.[11]
    • A ceramic round brush absorbs heat from your blow dryer to create ultra smooth results.
    • A boar bristle round brush has tightly packed bristles that can help you achieve smooth, frizz-free locks.

Dry the remaining sections the same way.

  1. Work on 1 section at a time until all of your hair is dry. Continue the same process with the round brush and the diffuser, keeping the heat concentrated on the hair wrapped in the brush. Be sure to get every section completely dry before you move on! Flat ironing damp hair can cause serious damage. [12]

    No, there isn't. However, using natural masks for your hair like egg and olive oil will make it look healthy and shiny.

    Brush your hair back starting at your forehead, and then all the way around. Then use a generous amount of gel to slick it back into place. Lastly, after the gel dries a bit, take a wood bristle brush ( or any short bristle brush), and lightly go over the brushed back hair. Smooth it down with your hands.

Article SummaryX

If you want to make your frizzy or curly hair straight, use a flat iron, also called a straightener, to smooth out your hair in sections. To start, apply a dime-sized amount of straightening product to your hair, which will protect it and keep it moisturized. Turn your flat iron on to the highest heat setting your hair can handle. For example, pick 250 for fine or damaged hair, 300 for medium hair, and 350 for thick or coarse hair. Put the top half of your hair up into a temporary ponytail or bun so you can focus on the bottom layer first. Once the iron heats up, iron the bottom layer of your hair in 1-2 inch sections, making sure to move the iron slowly from root to end so you don’t burn your hair. Once you’ve straightened the bottom layer of hair, undo your ponytail and do the same for the top layer. Finally, set your hair with a finishing serum or spray to keep it smooth.
