Great stuff

I love this product. I use it every day and without it I have limp hair. Sometimes even with it I have limp hair and then use the mousse, and the root volumizer on my dry hair to lift things ups. I have very thin, very fine hair. I also use the growth drops every night.

Great Thickening Spray

Love it, I use it every day and spray lightly over my whole head; it really helps to thicken up my hair and doesn't leave it sticky or oily.
