Great shampoo!!
This is the best shampoo I found for my fine thin hair. I feel like I’ve tried them all. Though nothing will really thicken my hair, it does help and gives me back some confidence.

great stuff.
Love this stuff. Takes such a tiny amount to do the job. It smells wonderful, suds up great, rinses well. Would buy it again.

Best shampoo for volume I have used
I love the smell and how my hair turns out after washing and air drying.
