Yes, hair can grow healthy under a wig. I like wearing them, especially now that it's colder, because they allow me to take care of my own hair while still having a low manipulation, protective style.
Yes, yes, and yes. I want to say that my mom's hair was to her ear in a lil' bob doo. And this was like 1 1/2 ago and now it is APL. All she does is wear a wig and wash and condition her own hair every two week with no heat. And every week she puts in moisturizer and corn rows it back up.
