Grow New Hair Shampoo / I've only been using it a few weeks so I'm not sure how much new hair growth in have but my hair feels amazing, it feels thicker and it's unbelievably soft! A little goes a long ways, I have very fine hair but very very long hair and a quarter size drop is enough to sudz up every bit of my hair and I don't have to use conditioner! I can't see myself buying any other product line after this.
