Currently on TRT/HRT and my testosterone is almost 3 times the amount it was before I started. Seeing extensive hair loss, 0 men in my family have it. Getting DHT tested shortly.

Seen a couple of threads on this but noticed there is always new products on the market so thought I'd ask ... what shampoo are you using to counter hair loss? Also will these DHT blocking shampoos affect your DHT blood test results in anyway?
I want to avoid Finasteride so im currently using Regaine and a German caffeine shampoo.
