This service is fantastic and worth way more than the cost. I had been struggling with hair loss for more than three years. I am very busy- "career women." Most probably stress-related. Spent hundreds of dollars on everything you could think about. Random supplements, random serums, and shampoos- nothing helped. With MDhair, I finally feel that I am treating the root causes of MY problem - and all products work together. The scalp serum, the supplements, and the shampoo. I felt better from day one. Now, after this kit for 2 months, I can definitely say that my hair shedding has decreased, and my scalp and hair feel clear shinier and thicker!! You need some patience, but it works.
