I had PPP on my head since I was 12! I'm 24 now. So, for 12 years I had these ugly white bumps. I tried so many remedies (toothpaste, olive oil, anti-fungal treatment) and none of them worked. I thought the only way to get rid of PPP would be to get expensive surgery, and have my privacy violated! I didn't want my parents to know about my problems. I read the reviews here and decided I have nothing to lose. I did half in one session and then the other half two weeks later. I was glad I did it that way. I'm amazed how smooth my head is now! Several bumps came back, but not near as severe as they had been! Thanks so much for this tool and kit!
