Lactic acid is an Alpha hydroxy acid (AHA). It helps in scalp exfoliation, dandruff reduction, and, ultimately, hair growth. It also helps remove tangles and makes hair smoother and more manageable. It breaks down the dead skin build-up in hair roots and removes the accumulated product.
The primary source of lactic acid is milk. Using hair care products infused with lactic acid 2 -3 times a week can significantly improve hair quality. It is one of the best acids for hair growth. The top five benefits of lactic acid are:
-
It helps break down the bonds that hold dead skin cells together and acts as a good exfoliant.
-
It protects the hair shaft from harm caused by UV rays and styling products.
-
Enhances hair texture.
-
Promotes blood circulation in the scalp.
-
It provides key nutrients and oxygen to hair follicles, thereby helping hair growth.
