I have naturally wavy and frizzy and THICK! I hated hastling with it. My hair lady used this in my hair and I thought I had died and gone to heaven. My hair wasn't frizzy at all. This product is a little on the expensive side but it is well worth it. I have thick hair and I only need a quarter sized amount to cover all of it. I also struggle with finding products that don't make my hair look greasy or leave residue... this product fixed that. It never looks greasy, there is never residue and it does not way my hair down. I would recommend this to absolutely everyone.
