I done some research in the web and the conclusion is that :
the problem is the number of receptor in hair which are attacked by DHT which cause hair loss(too much receptor).
But DHT is within Testosterone, a male hormone, even if Testosterone kill my hairs, I like Testosterone because I am a man.
So personally, i would never do something which could lower my DHT or Testosterone.
My question is :
Brotzu lotion lower DHT or Testosterone like finasteride ? or your receptor are protected from DHT ?
sorry for my bad english
