This shampoo is really good and provides great thickness to my hair. It's one I purchase often.

But this for my husband who has fine hair, he has tried many products and has stuck with this one, definitely works. 

I but this for my husband, he uses the whole range and loves it. It definitely works 

Purchased as a gift and recipient was very happy as uses this range

This definitely gives me hair a boost in thickness, I'm using the density drops as well. It's a moisturing conditioner as well but doesn't make hair greasy, I haven't had to change my frequency of hair washes.
