MDhair is the best thing that happened to me in the last year. I had COVID in May. After 4 months, half (!!) of my hair fell off. I was devastated. My Dermatologist said that there was no treatment for that - just patience. I had to do something. MDhair seemed the right choice with the customized kit - and it's fantastic. I am taking the scalp serum once a day, the restore supplements, the shampoo, and the collagen, and most of my hair is growing back. It s just two months, and I am curious to see what will happen in 6 months!! Love it.
