I had a great experience with the MDHair Restore system. I was looking for a serum with scalp benefiting ingredients that would create an environment for hair growth. And the serum did just that as I can feel added fullness in the crown area as well as some baby hair growth in certain areas. Loved the shampoo and conditioner as well. Worked great on my fine, thin hair. I would say just be consistent and patient :) Would repurchase and recommend.
