Madam C.J. Walker builds a business

"Sarah is the first person in her family who wasn't born into slavery in Delta, Louisiana. But being free doesn't mean that Sarah doesn't have to work. She cooks, she cleans, she picks cotton, she does laundry, and she babysits. And when she works, she wraps up her hair. One day, Sarah's hair starts to fall out! It's itchy, crunchy, patchy, and won't grow. Instead of giving up, Sarah searches for the right products. And then she invents something better than any shampoo or hair oil she's used before. Her hair grows and grows! That's when she decides to rebrand herself as "Madam C.J. Walker," and begins her business empire"--Amazon.com.
