Unlikely. As a black woman, she may well have crinkly hair which is difficult to style, so for her public personna, she wears a series of distinctive 'big hair' wigs.
I was under theimpression that many years of chemically treating her hair had left her virtually bald and that the large hairstyles she sports today are all wigs
well she may be loosing a great loss of hair it is usually from putting that chemical hair dye. shure when you are a star you usually die your hair alot and cut and get extensions and than when they reach an older age they usually loose there hair!
