Love, love, love this product. I have fine, wavy/curly hair and a LOT of it - enough that my hair is often mistaken for being very thick. This product does not weigh my hair down, leaves no residue and has actually reversed some serious heat treatment damage. I've noticed less breakage and loss of hair in general since using this product, I do not wind up with the oily scalp I would from lathering shampoos - which left me having to wash my hair every single day. I can skip 1-2 days of washing my hair if I want to with this product, I honestly cannot promote using this over the traditional lathering shampoos strongly enough.
