depends really on the glue, adhesive,
water based or solvent based
cant comment on tapes havent used tapes in my wearing game yett,
on the whole the peice isint going to dropp of youre head just because youve been in the shower,the bond will, could, loosen slightley depending on the temp.
but heres the thing it aint a bigg deal,
just watch the front hairline,you will prob have to do a touch up,
protect the hair with a shower cap, really you dont want to be washing the hair everyday.
this will greatly extend the life of the peice.
you should be washing the hair once in every 3 weeks,
offcourse this depends on youre lifestlye, work, hobbies,temp of the country you live in, ect
just search the posts threads for , washing, showering, bonding.
