We've been braid-obsessed for some time now. Not only for their playful appeal, but because a little braiding is the perfect pick-me-up for limp, dirty, or bad-hair-day tresses. Summer is the best time to up the ante on your braiding skills with a few grungy-hair-approved takes on the classics. Whether you have a thick or fine hair, expert hairstylist Sean Gallagher of Ric Pipino says that the trick to making those braids stick is starting with dirty locks. Hair that's a few-days dirty or dirty-with-product work excellently. An added tip is to use a thickening spray before you get to weaving, making hair a bit more sticky rather than slick. Check out these four beautiful options from Beauty High.
