Grow New Hair Shampoo / I have thin hair with very little volume left but this shampoo makes my hair feel so healthy and it just feels thicker. I do not need to use conditioner anymore either. Is it growing hair. You only use a tiny amount of it and one bottle will last you a long time and I wash my hair every day. I am going to continue to use this product as long as it's available because I really just love it that much!
