What African American woman used the trial and error method to invent hair care products in 1905?

• A. Madam C.J. Walker
• B. Annie Malone
• C. Mary McLeod Bethune
• D. Ida B. Wells

Answer: (A)

Focusing on how practical experimentation leads to real-world solutions, this question highlights a pioneering Black woman who turned trial and error into a successful hair-care line around 1905. She began testing scalp remedies and hair-straightening formulas, refining them through careful feedback and repeated attempts. Each adjustment made the products more effective for Black hair and scalps, and the results convinced her to build a full line of products. She also created the Walker system—training other women to sell and promote the products—which helped transform a personal invention into a national business. This combination of hands-on testing, product refinement, and scalable sales created a lasting impact on Black entrepreneurship and beauty culture.

Annie Malone was also a notable beauty entrepreneur, but the date and emphasis here align most closely with this inventor’s early 1900s work. Mary McLeod Bethune and Ida B. Wells were leaders in education, civil rights, and journalism, not hair-care product invention.
