I would recommend this hair regimen to anyone wanting to get their hair back. I have been using the shampoo, hair serum and hair supplements for 5 weeks. And I have already noticed a drastic difference in my hair in that short of a time. I could feel a little bit of a difference but when I took my second picture and compared it to the one I took on day one I was ecstatic. I ordered 2 more months supply and I added the collagen to my regimen. I'm so excited to see how much more hair I'm gonna have in 2 or 3 more months. MD Hair has a loyal customer in me for life.
