I am extremely happy with MDhair products. I’ve used the shampoo, scalp serum, and supplements as directed and see results. I first experienced less hair falling out. Very noticeable when I washed my hair and combed it out. Then I noticed baby hair growing where I lacked hair. Even my hair dresser noticed. I love the supplement and only having to take 1 pill. I was taking 4 of another supplement that didn’t seem to be doing anything (I was on that for a year) and no significant change. My girlfriend gave me MDhair before I decided to order it myself, so I’ve been using it for 2 month and getting results. This is highly recommended!
