Lignans from the roots of Urtica dioica and their metabolites bind to human sex hormone binding globulin (SHBG). |
Al tho I didn't know this I completely believe it. I did loose hair when I used activate and it hasn't grown back. I completely agree that it does increase dht in the scalp. I wish I had known this before. I would have never used it cause the hair still hasn't grown back to how it was before.
But I am also prone mpb so that made it even worse but now I know to stay away from any product containing this, im barely over 21 and I dont wanna make it worse. Thanks for informing us on this, I really did loose hair on the top back of my head around the exact time I used this so I def aggravated my genetic mpb.
