I don't use shampoo (no poo). A girl's guide to healthier hair.
Wash hair w baking soda and vinegar. Another pinned said: "My hair has grown a ridiculous amount and is now the longest it's ever been. It also takes 4 days for it to even get SLIGHTLY greasy, where as before it would start getting greasy in less than 18 hours. I will NEVER go back to regular shampoo."
