Annie Minerva Turnbo Malone (August 9, 1877 – May 10, 1957) was an American businesswoman, inventor and philanthropist. She is considered to be one of the first African American women to become a millionaire. In the first three decades of the 20th century, she founded and developed a large and prominent commercial and educational enterprise centered on cosmetics for African-American women.

She was born in Metropolis, Illinois, the daughter of Robert and Isabella Turnbo, who had formerly been enslaved. Orphaned at a young age, Annie attended a public school in Metropolis, before moving in 1896 to live with her older sister Ada Moody in Peoria. There Turnbo attended high school, taking a particular interest in chemistry. However, due to frequent illness, she was forced to withdraw from classes.

While out of school, Turnbo grew so fascinated with hair and hair care that she often practiced hairdressing with her sister. With expertise in both chemistry and hair care, Turnbo began to develop her own hair-care products.

While experimenting with hair and different hair-care products, she developed and manufactured her own line of non-damaging hair straighteners, special oils, and hair-stimulant products for African-American women. She named her new product “Wonderful Hair Grower”. To promote her new product, Turnbo sold the Wonderful Hair Grower in bottles door-to-door. Her products and sales began to revolutionize hair-care methods for all African Americans.
