AHA, Alpha Hydroxy Acid, is a chemical exfoliant that help to maintain oil production in hair nad helps our scalp breathe easily, by opening up pores. This is essential for healthy hair growth. Exfoliation becomes important when you last a few days between washes that might lead to an oily buildup. The act of stimulating the scalp through exfoliation, helps supply more nutrients and oxygen to your hair strands, leaving them denser and silky soft. 

All AHAs are naturally derived and classified by how they are derived. The most common ones include glycolic, derived from sugarcane; lactic, derived form milk; citric, derived from lemons and; malic, derived from apples. 

AHAs are ideal in hair products since they strip the hair of dirt and pollutants without stripping them of much needed moisture.
