My best friend's mother in law wears a wig for that reason. HAs for years. I never had a clue!!!
My mom wore one due to chemo that she ordered through the American Cancer Society. MUCH more reasonable prices than the wig store she went to, looked great, and she got more compliments on her wig than she ever got for her real hair!
I DO know they get hot, though. something to consider, especially in the summer. My aunt had one last summer (also due to chemo) and would just whip it off once in a while because she was just too darn hot! I LOVE that she was confident enough to do that BTW :)
