Agreed. Showering with just warm water is not a problem; it is just shampooing the hair system you need to be careful about. I sometimes shower 2 or 3 times a day if I have worked out or played sport, but I only shampoo my real sidehair. I just let the warm water from the shower run through the system hair and the lace mesh. That doesn't do any harm at all, and it is necessary t keep your scalp in good condition. I only shampoo the piece once a week though, unless I have been somewhere very dusty or smoky.
