Hey man, i didn't. But i had a very good regrowth on my crown, only using tea tree shampo and piroctone olamina 2%. Some ppl say it is too harsh for the scalp, but i was using piroctone olamina 2% everyday. Sometimes 2 times per day... And Tea Tree everyday 2 times. When i go shower, i use first tea tree, after piroctone olamina, and it makes my scalp very very clean. No irritations, and now i got regrowth on my crown.
Maybe cause tea tree and piroctone olamina has proven to have an anti adrogen function.
