Bogna McAndrew, an entrepreneur in London, quit shampooing her long, straight hair. She says her hair always looked best when it was a little dirty and she wished it could look that way when it was clean.
Six weeks after giving up shampoo, she said, "I love my hair now. I just didn't know there was any alternative to shampoo. I thought you just had to be a dirty hippie. I didn't know you could clean your hair any other way."
McAndrew uses a baking soda and water mixture once a week on her scalp, and she's learned about other shampoo alternatives including lemon juice and even beer.
"It has really opened my eyes," McAndrew says.
