Side Swept Graduated Bob

The shape in this photo is doing less work than the finish is. If you already wear a bob, the sweep, the flat tucked side and the stacked volume at the back are half an hour with a round brush and a comb — all of it styled in rather than cut in. On longer hair a stylist can pin the lengths under into a faux bob for an evening and you keep every inch. Worth saying plainly too: those ash-blonde ribbons are doing a third of the work here. The same shape in one flat color is a much quieter look.

What the deep part is doing

The part sits well past the natural line, above the arch of the brow, and it earns its keep three ways. It forces lift at the root on the heavy side, it throws a diagonal across the face that breaks up a round outline or a square jaw, and it hands you a long panel to sweep. The trade is the other side, which reads flat, shorter and severe by comparison — that asymmetry is the point, but some people hate it on themselves. Two things to test before you commit: whether a cowlick sits where you want the part, because a deep part landing on the wrong side of one will lift and split all day, and where the widest point of the bob lands. A graduated bob is widest at the jaw, which is a gift to a longer face and a problem if your cheekbones are already the broadest part of you.

The trim schedule you are signing up for

This is the higher-maintenance end of styling. Graduation grows out into a lumpy triangle rather than into a longer bob, so the shape needs a shaping trim every five to six weeks — a real recurring cost, and the reason people quit bobs. The blowout itself holds two days, maybe three on silk if you leave it alone, and humidity always collapses the sweep first. Fine to medium straight hair takes the shape most easily. Thick, coarse or curly hair needs weight taken out through the interior or the back sets like a mushroom, and if your curl pattern is tight, pressing it smooth every week is more heat than the look is worth.
