I am a healthy woman in my 50s. I suffered from more and more hair loss for a few years, which I attributed to my lousy hair genetics. I have tried Rogaine, Nutrafol, and a few other products without any noticeable results. A good friend recommended MDhair. I immediately liked this company. The approach was serious; they looked at the pictures that I uploaded to their website and sent a kit of products. After just three months, I am over satisfied with the results. It reduced the bald areas on the top of my scalp, and the hair filled much smoother, fresher, and thicker. I believe that using the combination of the serum, shampoo supplements, and collagen does the trick. They have excellent medical support - worth every penny. Love it!
