I first tried MD Nutri Hair supplements because I had a disaster at a hairdresser in London where the hairdresser broke off more than 3 inches of my hair so I was desperate to grow my hair back quickly. I saw a dramatic gowth of new hair along my hairline and it the thickness of my hair. Along the front of my face hairline I saw a lot more new baby hairs, which continued to grow longer. I never worried about my hairline before, but it looked great, really youthful. Most importnantly for me, I could feel my hair thicker at the root, and this thickness continued as I took the supplements (once a day). I did notice less hair falling out in the shower too. I think the product increases the growth cycle and reduces hair loss- so the improvement is dramatic in less than a month! Fantastic- I totally recommend this product: 0
