Sometimes all of the dry shampoo in the world isn't going to be enough to boost volume in dirty hair. Don't spritz $5 worth of dry shampoo into locks to try and make a difference. Embrace the flattened finish of unwashed strands with a gelled half updo. Bring the front layers of hair to the back of the head and mist with hairspray, like Living Proof Control Hairspray, $26. It's an on-point look that gets greasy strands off foreheads.

Sparkly makeup can distract from unwashed hair, but there's no need to rely on tricks. An easy half updo, like this asymmetrical look, can easily conceal greasy roots. Just part hair on the side, twist it behind one ear and pin in place. Voila, a good hair day.

Short-haired women and members of #teambob don't have enough length to rely on updos to camouflage greasy roots. Clipping sections of hair back is a good solution but a simpler alternative is to brush hair back and leave the clips off. Greasy hair tends to have more hold and will stay brushed back, but for extra staying power (and to make the look intentional), apply a gel to roots, like Redken Hardwear 16 Sculpting Gel, $19.50.

Boxer braids are being embraced whether hair is dirty or clean. Switch up the greasy hair hairstyle by splitting each braid into two halfway through each plait. The unique detail gives the eye somewhere to focus besides roots.

Having a selection of headbands to handle no-wash days is a smart move. Different placements will keep the look fresh. Try a thick headband placed slightly off center and over the ears. Tuck the rest of hair into an updo. Greasy roots? What greasy roots?
