The first step is to understand what’s causing the frizz in the first place so you can take the appropriate precautions. Frizz is mostly caused by a lack of moisture in your hair or humidity and excess moisture in the air. Another common cause of frizz is dry hair or damage. Let’s say you have dry or damaged hair and you go outside when it’s humid—what happens to your hair? The hair is dry, which means it wants to absorb all that moisture from the environment.

1. Choose a sulfate-free, glycerin-packed shampoo.

When selecting a shampoo, look for products with glycerin listed high up on the ingredient list. The closer glycerin is listed to the top, the more concentrated it is in the product. Glycerin helps combat frizz by penetrating the hair and hydrating it from the inside out. It is also a great humectants, meaning it absorbed that extra moisture in the air and creates a protective coating over the outside of the hair keeping moisture trapped in.

2. Always use conditioner.

The power of a good conditioner is often underestimated. Ensure you use conditioner every time you shampoo your hair to keep the cuticle hydrated so moisture can penetrate deep into each strand. This helps prevent the cuticle from opening up and letting excess moisture from the environment in, which will keep it smooth. When searching for a conditioner, look for a product that contains glycerin, as well as other hydrating ingredients like shea butter. Be sure to apply conditioner from the mid-lengths down to your ends and keep it away from your roots to prevent oiliness.

3. Twice a week, only use conditioner on your hair.

You might think your hair needs to be shampooed several times a week, but in reality, it actually doesn’t. Every two days, apply conditioner only and skip shampoo, then rinse it out. The conditioner contains a small amount of surfactant, which is what shampoo uses to cleanse your hair. As well, conditioners contain a small amount of oil which attaches to the oils in the hair, cleansing it away. This also called “Co-Washing” which helps keep the hair at optimum PH as you are replenishing moisture and ensuring the natural oils in your hair are not being stripped away.

4. Use a hydrating mask once a week.

Keeping the hair hydrated helps to prevent the hair cuticle from opening up and letting in moisture, which is the biggest contributor to frizzy hair. Try doing a hair mask or a specialized hair treatment once a week to keep hair moisturized and less prone to damage from styling. Look for products containing coconut oil or castor oil—both are amazing for hydration and will give your hair an incredible shine.
