Bad hair days were made for ponytails, braids and whatever other bad-hair-concealing hairdos that are fast and easy. But instead of just throwing your hair up in a blah 'do, give it a little pizzazz and ward off those bad-hair blues with a few tricks and pretty accessories. If the problem is needing a wash, then shake a little baby powder (for blondes) or bronzing powder (for brunettes) onto a clean, big makeup brush and brush onto roots evenly. Brush through while holding your head upside down, and that should take care of the greasies. If not, then a wide headband will cover those oily parts. One with a sleek bow or in a patent leather style would be on trend right now. A sleek ponytail can cover up a host of ills - frizziness, oiliness and even a bad dye job. Smooth hair back and use a little gel or styling spray to keep it in place. Use some small, sparkly barrettes to tame strays, and eschew the scrunchie.
