Ad. In 1905, Sarah married Charles Joseph Walker and changed her name to Madam C.J. Walker. Charles was her third husband. Madam Walker then went on to start a business, promoting a scalp treatment called Madam Walkerâs Wonderful Hair Grower.

She did, however, go on to grow her business to include hair and scalp treatments, salons, and training schools. The Madam C. J. Walker Manufacturing Company factory was built in Indianapolis in 1910.
