I was having hair loss and hair thinning. Two Bald spots I have covered with Bangs. This problem has persisted for about 8 years now. I tried Nutrifol, Karanique, Biotin, Rogain, along with all the oils (tea tree) (castor) . I felt my pony tail get smaller and smaller. I happened to come in to see Dr. Plaman who gave me a prescription for two pills. After about 5 months I began to see a difference. Its been close to a year and my thick hair is back. It is a mere miracle. I know I am old and I will experience thin hair but not to the extent it was happening. I am happy with my results. I would and do recommend Precision Hair to others.
