I didn't want to write a review until I'd given the product over a month's assessment. I have re-ordered prior to this posting.
I suffer from thinning hair in the frontal-hairline area (old age, "the changes":)
No fragrance, no side-effects, no oily or drying effect.
After 3-4 weeks use as directed I noticed new hair growing in (I couldn't imagine why that area had "bumps"). My now white hair has new BLACK hair growing in and my brushing and shampooing have fewer hairs that decided to leave the family!
Look...I very rarely write reviews. I'm posting my truth and experience only. I take this topic very seriously as I know you do.
