The Dariya magic sheets are basically like flat Velcro rollers. They are designed to hold the hair back while you wash your face, or do your makeup.
... Unecessary right? *laughs* kind of... I used to just you a headband or put my hair back in a pony tail. But they looked cute... Damn, I can’t resist cute packaging.
Anyways, they are actually nice to have around. They do a much better job of holding the little short fringe hair than a head band. They also don’t mess up a hairstyle. I always end up with a pony tail line... Which I hate, because no amount of styling gets rid of it. Plus, if you are doing you make up, they do help prevent you from accidentally getting stuff on your hair. I generally set my foundation with loose powder, and the finly milled stuff can certainly drift off teh brush.
Conclusion Yeah, okay, they aren’t a beauty essential. But they were cheap, and I like ‘em. So :P
