Final answer:
Madame C.J. Walker created hair treatment products, particularly for African American women, which allowed her to achieve remarkable success and become a self-made millionaire.
Step-by-step explanation:
Madame C.J. Walker achieved success by creating hair treatment products. In the early 20th century, she developed a line of cosmetics specifically for African American women, which included the wonderful hair grower, a scalp conditioning and healing formula. Walker's innovative beauty products revolutionized the way women, especially black women, cared for their hair and contributed significantly to her becoming one of the first American self-made female millionaires.
The beauty industry transformed significantly with the rise of marketing and the idea that women needed to purchase certain cosmetics to feel and look beautiful. Although make-up initially had a negative stigma, over time, the industry expanded to include not just facial cosmetics, but also lotions, perfumes, and accessories, suggesting a broader societal acceptance and desire for such products. Madame Walker tapped into this evolving market but focused on creating products that catered to the specific needs of black women's hair during a time when such options were scarce.
