The Indian hair export market is estimated to be worth about $393.5 million annually, with a yearly growth rate between 10 percent and 30 percent. Indian hair companies tend to export two types of hair: Remy and non-Remy. Remy hair is usually collected from temples and is of the highest grade. Non-Remy hair is processed. Because Non-Remy hair has cuticles that do not face the same direction, it is treated with hydrochloric acid to remove the cuticles. This reduces the quality of hair.
Africa is a prime market for Indian hair. Its dry hair market (the market for weaves, wigs, and extensions) is currently estimated to be worth $6 billion a year and booming. The market is so big that global giants such as Unilever and L’Oreal are investing heavily in African hair care products.

These companies are getting rich because of our need to have hair like that of white people? Why are we ashamed to wear our hair as it is? Why do we keep using chemicals that damage our hair so we can get it to look straight?
