High End Shampoo with Thinning Hair

This is a densifying shampoo for thinning hair and was recommended to me by my hairstylist. I like KM products for the sulfate-free and lux feel they leave on my hair. Bottle looks small but it lasts a long time. A tiny, pea size amount is all that is needed for my shoulder length hair. My hair feels fuller with more volume and leaves no residue on my strands.
