SAFFRON HAIR & MAKEUP DILEMA: BABY HAIR

BABY HAIR OR NO BABY HAIR..THAT I THE QUESTION! WHEN IS BABY HAIR ACCEPTABLE?  When your a baby? When your edges naturally lay that way? When you have a bald spot? This has always been something that puzzled me. I'm kinda on the fence with this one (maybe because Im guilty of this one myself! ;)) What do you guys think? Is this a big style faux pas? Is it ever OK to fake baby hair? Thoughts???
