pk, Ive seen so many different people post so many different opinions on this subject its somewhat unbelievable but for now I'll tell you what "works for me". To begin with I dont have an oily scalp and I dont sweat much. I never wash my piece with it on my head, I always do it seperately and very gently 2 and sometimes 3 times a week.I let it damp dry in a towel before I mess with it. I shower everyday and I do use a little rinse everyday but not much . My piece never smells , always looks good (except right now as I accidently poked a hole in it) . lol To be honest I'm lost as to why there would be a smell to it even if you left it on over a week but what the hell do I know. There have been people on here that dont remove their piece except for once a month

if you ask 100 people on here you're going to get 100 different answers to some very large varying degress.
