From the first self-made woman millionaire Madam CJ Walker to today’s beauty moguls such as Carol’s Daughter, Miss Jessie’s and Bronner Bros., the business of black hair has grown from a flea-market delivery of kitchen concoctions to a multi-billion dollar mainstream industry. Today, black hair care corners an estimated annual $2.7 billion of the hair care industry.

But black hair care as an industry hasn’t always been respected or recognized by the mainstream. In the video below, CNN interviews image activist Michaela Angela Davis; Miko Branch, co-founder of Miss Jessie’s and Lisa Price, founder of Carol’s Daughter who talk about the political history of black hair, the natural hair movement and its resurgence, and the renewed wave of hair care innovation and entrepreneurship.
