I've been taking testosterone booster and started losing hair.

I suggest a formal consultation to determine what is best.  This requires assessment to determine the best treatments.  Best, Dr. Emer.

mazztm,Sounds like the testosterone booster is working. An increase in serum testosterone will likely trigger increase hair loss in the genetically predispose individual. It takes two things: 1. genetically inherited pattern of hair with sensitive to DHT; 2. Testosterone or more accurately DHT it's metabolite. The interaction of the two leads to shortening of the anagen growth phase of hair. Hence the hair grow less and less until they are so thin and without pigment becoming  less visible.Sincerely,Bernardino A. Arocha, MD

To obtain alive hair follicles implanted in higher rates, the latest technique being used is not the only manner, it is also affected by compliance of implantation area that we found a better way to improve as a result of our researches, The Organic Hair Transplantation. By this new and unique Organic Hair Transplantation Technique, before the extraction and implantation processes; we regenerate the implantation area with injection of stem cell enriched fat tissue. Regeneration of cells in target area before FUE transplantation with the support of stromal stem cells results in higher rate of alive thicker hair follicles
