Nioxin shampoo for your hair (plus you won’t go bald! hehe). I have a paul mitchell system
paul mitchell
Botanical prep shampoo
botanical hydrating shampoo
botanical body-building rinse
It pulls impurities out of your hair (chlorine, dht, pheromones, ect.)
As for your skin. Who knows… If your worried about build up just scrub that area thoroughly and skip a day or more of phero aplication.
