I just finished using my first set of the shampoo and conditioner for thinning hair and I can definitely tell a difference! I just turned 60 years old this month and I've always had very think, wavy long hair. Just recently I've noticed some thinning on the top, back of my head, near the back of my part. Since using this, I have noticed that that area is growing back and I have many new baby hairs around my temples and forehead. I'm really excited about that because I've always gotten compliments on my "thick head of hair!" Don't want to lose it now! I just ordered more and I'm on the subscription for every 2 months for more. I love the way my hair feels and it feel so soft and bouncy! I will use this forever! :-)
