Excellent product - does what it claims to do. Makes hair softer, thicker without harmful chemicals.

I am 81 years old and my hair is getting thinner. I've tried many products but yours seems to be the best with me no longer having to revert to "comb-overs". I like the way it makes my hair feel when I'm shampooing it, as if it is thicker right then and there. I recently sent two of Jason Natural Thin to Thick product to a young man in England who is dismayed by his thinning hair. Hope it works for him.

good hairday

Posted by 5314606838264875460 on Nov 09, 2015

I have a "baby-fine" flexible hair which is very flat on the head. I've tried many tricks to give it volume but nothing really lasts for more than an hour or so. This shampoo actually has given me a good hair day! The hair is soft and not freezy and the scalp feels very clean, but it didn't give me the extra volume or hair thickening i was hoping for. Im still happy with using it but i think that on the next order i will try different shampoo that will give me volume... Until I'll find the one!

Doesn't work for me

Posted by Reviewer1176335 on Jul 04, 2016

I've bought this shampoo several times over the years but I don't see a difference in the way my hair feels or looks. I keep coming back to it because I think it's a good product even if it doesn't work for me.
