Does the name Annie Turnbo Malone ring a bell?
She was the real first black female self-made millionaire. Born in Illinois, she made a natural hair growth product called Wonderful Hair Grower and had salespersons, one of whom happened to be Sarah Breedlove aka Madam CJ Walker. Annie had beauty schools called The Poro Schools which trained women to do hair and sell the product. She was a philanthropist as well. Her history has been overshadowed by the more well known history of Madam CJ Walker who learned everything she knew from Annie Turnbo Malone even calling her product Wonderful Hair Grower. Sounds like trademark infringement to me!
