Must Have
Amazing. Nothing short of amazing. If you have fine or thin hair, this is the product. It makes my hair feel soft without being too soft or weighed down. My hair has volume and is bouncy. Doesn’t make it greasy or gummy or dirty feeling. all.

This does nothing for volume. All it does is make your hair incredibly greasy the next day.
