Hair loss has been bothering me for years now. It started in my late 20s and got worse in my late 30s. I tried the year's many different shampoos and hair supplements without any results. I felt that those products are one size fits all. Not something personalized for me. Based on a friend's suggestion, I tried MDhair, and it was a totally different experience. I believe it's the combination of external treatment with eths calp serum and shampoo with the oral supplements that do the trick. I am impressed. Seeing the hair loss reduction in 2 months is a treat. Great product.
