Eeek! No! My best friend has 4a curls and whenever she wears them "natural" she flat irons her bangs and glues them stiff with product. She's a lovely woman, and she looks gorgeous with her natural hair. Every time I see those flat, gluey bangs I think it looks like she's wearing some kind of clip-on hairpiece that looks really fake...
She claims she straightens them because her hair is very fine and she thinks you can see her scalp too much when her bangs are curly. She thinks flattening out the hair covers her scalp, I guess. Personally, I don't notice her scalp showing through, and I think it's residual "anti-curl" mentality from ages of thinking her hair looked bad curly.
