The Middle Part
The signature style of ’70s beauties, this straight-down-the-center look is a chic option for any occasion or face shape. It’s a classic. For the most precise part with less risk of snagging, use the tip of a rattail comb to divide hair. If you try to part hair using the comb’s teeth, you'll encounter more tangles.
A jagged line is fun and casual and flatters any face shape. Better yet, it's a great way to camouflage overgrown roots. Highlights and color are generally applied to hair that's parted in the middle or slightly to the side, so obscuring the part can obscure the line of demarcation. Use you fingers to move narrow sections of hair to either side until a zigzag is formed.
The Diagonal Part
This effect adds polish to a chignon and slims a wide face. Divide hair from above the outer corner of one brow to the back of the crown on the opposite side. Slick hair back into a bun or a ponytail.
The deep side part
A cousin to the side part but far more dramatic (think day versus night), a deep division is a natural volumizer for hair of any kind, since more hair on one side equals more body by definition. If your face is slightly round, allow the side with extra hair to fall slightly across your face.
The Side part
Almost everyone has hair that falls slightly to one side or the other naturally, so this look complements most, regardless of face shape. For a casual feel, use your fingers to part your hair rather than a comb. A side benefit: Switching your part from one side to the other can mask thinning.
