Tiktok Trending Glycolic Acid For Your Hair


Updated On

We are no strangers to glycolic acid. We often hear and see this acid on skincare brands. But glycolic acid for your hair? Hmmm…not until a trend started on Tiktok. Apparently, glycolic acid can cure dandruff. I needed to find out the science behind this claim. So I did some reading and here is what I discovered. Glycolic acid is a water-soluble alpha hydroxy acid (AHA) that is commonly used in skincare products. It is a water-soluble crystalline solid that is highly soluble in water making it easily absorbed by the skin. It is commonly used in skincare products to improve skin texture and slow down aging. It is also a powerful component of acne-fighting products. But what does it do to the hair? What is glycolic acid on hair products? To explain the benefits of glycolic acid in the hair, let us go back to how it works on the skin. Glycolic acid works by creating a peeling effect on the skin. The glycolic acid absorbed by the skin breaks the bond between the top layer of the skin and the next layer. Thus creating a peeling effect that reveals the new and younger skin underneath. Apart from this, on acne-prone skin, glycolic acid acts as a peeling agent for gunk and oil build-up on the skin preventing acne.

How does this apply to the hair and scalp? How do you use this in the hair?

In the same way, glycolic acid works on the skin, glycolic acid when absorbed by the scalp weakens the bond between the dead skin and the newer skin underneath. Thus removing flakes and dandruff on the scalp. Many of you will ask if glycolic acid can also make the hair grow longer and stronger. The answer is that a healthy scalp breeds healthy hair. We all know that healthy hair comes from a healthy scalp. Once your scalp rakes in the benefits of glycolic acid, with the help of other compatible hair care products, you can have stronger and healthier hair.

How to apply glycolic acid to the hair?

Apply glycolic acid on your wet or dry scalp as a pre-shampoo treatment. Leave it for a few minutes and wash it off with your regular shampoo and conditioner. Do this once or twice a week.
