I started using this product 5 days ago and I am really impressed. I have used the Yes To Carrots Shampoo and Conditioner for years with decent results, but I've seen better results in less time with Yes To Blueberries.
I have very fine, un-dyed, curly/frizzy hair that I do not style, straighten or blow-dry (I am caucasian); I let my hair air-dry and shape my curls with my fingers. After using this shampoo, my curls are smooth and fall into ringlets. It doesn't give it any additional volume, but that is a minor complaint. I am hooked. Also, the scent is mild (milder than the blueberry face products) and not distracting.
