I am taken back by the growth of my hair in such a short period of time. I work in a job that is face to face for clients and my self esteem and productivity has gone up exponentially. My hair is the longest it has ever been now! Without this serum, I guarantee life would have turned out differently. And I don’t mean in a good way at all! I highly recommend Dr. Donaldson’s approach and treatment for hair loss and hair thinning.
