Been using “Hair Surge” shampoo for years. It helped slow down my hair loss but was doing nothing for regrowth. I started using minoxidil in combination to spur regrowth. The combination was working fine for about 6 months then suddenly I noticed increased shedding and hair loss after starting a new bottle of hair surge. No happy seeing how pricy it is. Spent half a Saturday researching shampoos by ingredients and reviews. Decided to give ProBliva DHT blocker a try after researching the active ingredients ZINC BCA and Kapilarine. Been using for over a week now and I’ve noticed results. Shedding stopped after 2 uses and is less than I’ve seen in years. My hair has better volume and is less oily at the end of the day. It’s a serum so a little goes a long way. Has a very rich lather and mild cinnamon baby powder scent. Seems to be controlling excessive sebum and blocking DHT well. I’m impressed with the short-term results and hope to see some regrowth soon.
