Madam C.J. Walker was arguably the first self-made black woman millionaire. She was an African-American businesswoman, hair care entrepreneur and philanthropist. Her own hair loss (due to scalp disease) inspired her to experiment with developing shampoo and an ointment that contained sulfur to make her scalp healthier for hair growth. She began with a mail order business that started in Denver and led her to establish her headquarters and build a factory in Indianapolis. She made her fortune by developing and marketing a hugely successful line of beauty and hair products for black women under the company she founded, Madam C.J. Walker Manufacturing Company. The Guinness Book of Records cites Walker as the first woman to became a millionaire by her own achievements.
