Sorry if this has been addressed. Didn't find anything in the "search." But I've always wondered how many times you are suppose to use these. I definitely use mine more than once and that number can easily double if I need to make a trip to the BSS and it quadrupled when I was in college. Even after a good wash, do you think some kind of bacteria grows in them? With my damaged hair the last thing I need is a bacterial infection of the scalp!!! LOL!
By the way, I noticed that the plactic caps I buy at the BSS are inferior to Sally's...guess that's why they cost more.
