By the beginning of the 1900s, Turnbo moved with her older siblings to Lovejoy, now known as Brooklyn, Illinois. 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.
