How To Heat Train Hair With Natural Texture: 3 Expert Recommendations

We’ve all been there: You take your time in the morning, smoothing your curls into a chic, loosened style…but within a few hours, your sleek strands have returned to their naturally textured selves. It leaves you longing for a way to achieve loosened curls that last—without turning to chemical relaxers that can permanently weaken your hair.

Enter heat hair training. When you heat train hair, you encourage your strands to hold straighter styles longer, even when exposed to humidity.

Heat training natural hair requires a bit of know-how to avoid ending up with heat damaged curls. All you need is a little extra TLC, & our guide to how to heat train hair.

Step 1: Understand Heat Training for Natural Hair

Heat training refers to repeatedly straightening your natural textured hair with any hot tool like a flat iron, blow dryer, or hot comb (aka a Marcel comb if you’re feeling old school). The goal is to “train” natural curls to loosen more easily & resist reverting back to their natural texture when exposed to humidity.

Why try heat training? Fans of heat training say that it:

  • Makes styling easier over time
  • Minimizes heat & styling damage
  • Avoids the use of chemical relaxers
  • Cuts down on tangles
  • Maintains the curl pattern so hair can be worn in curly or natural styles when desired

Does Heat Training Work for Natural Textures?

As anyone with textured hair knows, managing your style can be a bit of a juggling act—you want to keep your hair healthy, undamaged & hydrated—while enjoying a range of styling options.

That’s where heat training comes in.

By repeatedly straightening your strands using gentle heat, the hair cuticle relaxes without fully losing the natural curl pattern. This way, you can switch between your natural texture, looser curly or wavy styles, or fully straightened hair whenever you like.

So does heat training work for natural textures? The answer is yes—but it’s important to approach heat training with caution. Curly textures are naturally more susceptible to damage simply because hair oils can’t travel down the hair shaft as easily as they can with straight hair.1

How Many Weeks Does It Take To Heat Train Natural Hair?

The amount of time needed to train your hair will depend on how tightly textured your coils are.

For looser coils, it can take a month or two of heat styling once a week to notice a difference. If you have very tight curls, it may take up to 6 weeks of a heat training regimen to reshape the hair shaft.

Keep in mind that weekly heat styling can easily lead to damage that builds up slowly before you notice it. Be sure to pay close attention to your hair’s condition & watch for signs of accumulating damage.

Step 2: Protect Natural Hair While Heat Training

The truth is, all styling causes some damage to hair. In fact, research has shown that even washing your locs can harm the cuticle since water absorption may cause swelling & shrinking of the strands.2

Still, damage from heat training can be minimized as long as you take a bit of extra care. When heat training natural hair, be sure you:

What Is the Safest Way to Heat Train Natural Textures?

The key to safe heat training is to remember that it’s a process that takes time. Don’t use high heat or heat train more often to try to speed up your results.

Here are a few more of our top tips for safely heat training natural hair:

  • Don’t heat train between washes – While it may be tempting to do a touch-up with your flat iron in between wash days to maintain your sleek locks, it’s best to skip using heat tools between heat training sessions. Your hair should always be fully prepped with a heat protectant before heat styling, which is easiest to do on wash days.
  • Start with lower temperatures – Heat training is all about going slow & gradually reshaping your hair. Experiment to find the lowest temperature setting that will still give you the results you want. As your curls become more relaxed, you may not need as much heat to get the same results.
  • Take breaks in between heat styling – Over-exposing your hair to heat can cause serious damage. Try giving your hair a break in between heat styling sessions by wearing a wash-&-go look once a month or so. This will not only give your hair a rest, but also allow you to check that your natural curl pattern isn’t being damaged by heat training. To keep your hairstyle looking fresh, try using curly hair stylers to extend the wear of your look.
  • Skip the flat iron, stick with the blow dryer – After blow drying curly hair, some will go back in with a flat iron for an ultra-sleek look. However, flat irons are more damaging than blow dryers, so opt for your blow dryer as much as possible. If you do flat iron, don’t leave the flat iron in one place for too long. Try not to make more than two passes on any section of hair.

  • Step 3: Know the Warning Signs of Heat Damage

    There are a few signs of heat damaged hair to look out for. You’re probably heat training too much if you notice:1

    • Your hair seems less shiny & more dull
    • Your stands are experiencing a surplus of split ends
    • Your coils remain flat, even after a wash
    • Your locs begin to break, especially when combing

    Does Heat Trained Hair Frizz Easily?

    One of the concerns those with curls often have about heat training is that it will make their hair more prone to unwanted frizzing.

    If your goal is avoiding unwanted frizz, the good news is that heat training can actually help to reduce it. This is because when you heat train your hair, you are essentially sealing the cuticle. To boost the cuticle-sealing effects, be sure to:

    • Use heat protectant before styling with a heat tool
    • Finish with a shine spray for curly hair or oil to seal in moisture & prevent flyaways caused by dryness

    Lastly, keep in mind that frizz isn’t the enemy. As long as your hair is healthy & moisturized, frizz doesn’t necessarily mean your hair is damaged. Instead of fighting it, remember that a bit of frizz can add volume & bounce to your style.

    Quick Tips: Heat Train Your Hair Like a Pro

    First, make sure your hair is in good condition before you try heat training. If your hair is already brittle or weakened from other treatments like bleaching, coloring, or chemical relaxers, heat training may not be your styling go-to.

    Instead, dedicate your hair care routine to restoring your hair’s strength with trims, deep conditioning & protein treatments before beginning heat training.

    Once you’re confident your hair is in a healthy state, follow these steps to start gently heat training:

    1. Always begin by washing & conditioning your hair with a gentle, non-drying shampoo & a rich conditioner. Some hair care experts recommend using a deep conditioner every time for extra hydration.3
    2. Apply a product like PATTERN’s Leave-in Conditioner & carefully detangle your hair. Remember, wet hair is weak hair.1 Always comb or brush very gently when your strands are damp.1
    3. Apply Heat Protectant spray or a serum evenly throughout your hair. Section your hair to make sure you don’t miss any areas.
    4. Using a paddle brush & a blow dryer for curly hair on low or medium heat, work through your hair in small sections. Hold the blow dryer about 8-10 inches from the hair, & always keep it moving from the roots to the ends to prevent damage.2
    5. Don’t heat train every day or even every few days. For most, once a week is a good schedule.
    6. Pamper your hair between heat treatments using a product like our curly hair mask. Schedule monthly trims to keep ends healthy, use ultra-hydrating hair masks regularly & wrap your hair in a silk scarf or PATTERN’s Satin Cap at night to prevent excess friction damage.
