i have recently been to men's hair club and seen by scalp with a microscopic camera. there was tremendous sebum buildup in the area that is shedding and thinning (the top); the back and sides looked extrememly healthy. i definitely think that excessive sebum buildup could be a primary cause of hairloss regardless of excessive DHT, or perhaps the sebum is an effect of the DHT. can anyone recommend a follicle cleaser shampoo and where to purchase it?
