So I started using the MDhair serum and shampoo less than a month ago, and I am already seeing noticable results. My hair actually feels healthier, thicker and I can see new growth coming in. The product is gentle, smells great and doesnt leave any greasy residue. I love how easy it is to use and it truly works. I really can't wait to see more progress with continued use. It's definitely worth trying if you are looking for real hair growth results.
