KMS ADDVOLUME Shampoo for Fine & Weak Hair - Volumizing & Strengthening Formula, 10.1 oz - Perfect for Thin, Flat Hair & Daily Volume Boost

I’ve bought this several times now. It really does add body to thin hair, cleans well, has a mild minty smell. My husband liked that it gave my hair body and tried it on his thinning hair— now we both use it. It’s a bit expensive, but worth it.
