16 Undercut Bob Haircuts From Hidden Nape to Bold Side Shave

The bob on top grows out slowly and looks fine for six to eight weeks. The shaved section underneath does not. Buzzed hair starts looking fuzzy within three weeks, and a fade needs even more attention, so anyone considering an undercut bob should plan on a quick clipper visit between full cuts. What you get in return is a bob that’s lighter, cooler, and faster to dry, especially on thick hair, plus the option of hiding the shave entirely or showing it off. The styles below range from a nape shave nobody sees unless you tuck your hair to a full side buzz with a design.

Hidden Nape Undercut Bob

The starting point for most women. A small section at the nape, roughly the width of the hand, is buzzed close, and the bob above it falls right over the top so nothing shows when the hair is down. Tuck the sides behind the ears or pin the back up and the shave appears. It removes bulk from thick hair, keeps the neck cool, and stays fully office-safe. Most women find they never want to go back once the weight is gone.

Side-Shaved Undercut Bob

One side buzzed from the temple down to behind the ear, with the chin-length bob falling over it or swept to the other side. This is the classic bold version. The contrast between the smooth bob and the shaved side is the point, so it looks best when the bob is sleek and the shave is fresh. A deep side part sends more hair to the long side. Plan on clipper visits every three weeks to keep the shaved side crisp.

Blunt Bob with a Shaved Nape

A blunt chin-length bob with the nape shaved high enough that a strip of it shows below the hemline from the back. Unlike the hidden version, this one is visible on purpose. The sharp bottom line of the bob against the buzzed skin gives a clean, graphic finish. It suits straight hair best, since waves blur the line. The visible strip needs to stay tidy, so this is the higher-upkeep way to wear a nape undercut.

Asymmetrical Undercut Bob

One side cut to the ear with the undercut beneath it, and the other side left at chin or jaw length. The asymmetry does more than the shave, since the whole shape leans to one side. It flatters square and round faces by breaking up width, and the long side can be tucked or left to fall against the cheek. A flat iron on the long side shows the contrast best. Trims are needed on both the short side and the shaved section.

Stacked Bob with an Undercut

A stacked bob graduates at the back so the layers build a rounded crown, and adding an undercut beneath the stack takes the weight out of exactly the spot that tends to get bulky. The result is height at the crown with a clean, close nape. It’s a strong option for thick hair that puffs out at the back. The undercut is mostly hidden by the stack, so it’s a quieter version of the trend.

French Bob with a Hidden Undercut

The French bob sits at the jaw, slightly tucked under, often with bangs. Adding a hidden undercut at the nape lets the short bob curve under more neatly, since there’s less hair pushing the ends outward. Nothing shows from the front. It’s the version to pick if you love the shape of a French bob but your hair is too thick to hold it. Trim the undercut every four weeks to keep the curve clean.

Undercut Bob with a Shaved Design

Once one side or the nape is buzzed, a barber can shave a design into it: parallel lines, a curve, a small geometric pattern. The design shows when the hair is tucked or pinned and hides when it’s down. Keep the design simple, since detail blurs as the hair grows. Designs need a refresh every two to three weeks, so this is the highest-maintenance option on the list, but also the most personal.

Fade Undercut Bob

Instead of a hard line between the bob and the shave, the undercut is faded, going from skin at the bottom to a longer length where it meets the bob. The blend is softer and more wearable, and it grows out without an obvious step. Fades take more skill, so book a barber who does them regularly. The fade needs attention every three weeks since the gradient is what makes it work.

Wavy Bob with a Side Undercut

Loose waves through a chin-length bob with one side shaved underneath. The waves add softness that balances the edge of the shave, and when the hair is swept to the long side the volume doubles. It works especially well on naturally wavy hair. Air-dry with a curl cream or use a large curling iron and leave the ends straight. Keep the shaved side smooth so the contrast with the waves is clear.

Curly Bob with a Tapered Undercut

On curly hair, a tapered undercut at the nape and sides lets the curls on top form a full, rounded shape without the bottom getting wide. The taper is cut gradually rather than in one line, so the curls above blend into it. This is a favorite for tight curls and coils, where it keeps the shape controlled and the neck clear. Curl cream and a diffuser bring out the definition on top.

Undercut Bob with Curtain Bangs

Curtain bangs soften an undercut bob at the front while the shave adds edge at the back or side. The bangs part in the center and sweep to each side, blending into the front layers. This combination suits women who want the practicality of the undercut with a softer, more classic face frame. The bangs need trims every four weeks and the undercut every three, so pair the appointments.

Double-Sided Undercut Bob

Both sides shaved from the temples down, leaving a wide strip of chin-length bob down the center and back. This is the boldest version, with a shape that leans toward a long mohawk when the hair is pushed up and looks like a normal bob when it’s down. It suits thick, straight hair and a strong sense of style. Both sides need clipper work every three weeks.

Micro Bob with an Undercut

A very short bob cut at the ear or just below, with the nape and lower sides undercut so the little bob sits neatly against the head. The proportions are the point: a tiny, sharp bob with a clean shave underneath. It works on straight or lightly wavy hair and suits fine features. The bob needs trims every four weeks to keep the length, and the undercut on the same schedule.

Undercut Bob with Contrast Color

Leaving the shaved section its natural dark color while the bob on top is lightened to blonde, or dyeing the buzzed area a vivid shade under a natural bob, turns the undercut into a color detail. The contrast shows whenever the hair is tucked or pinned. Vivid colors on the short section fade quickly but are cheap to redo, since the area is small. Bleached tops need a purple shampoo to stay bright.

Slicked-Back Undercut Bob

Comb a side-undercut bob straight back with gel or pomade and both the shaved side and the shape of the head show fully. It’s an evening styling option that turns the shave from a hidden detail into the whole look. Use a fine-tooth comb for clean lines and let the product set. It holds through humidity and shows off earrings and the jawline. Works on any undercut bob with at least three inches on top.

Shaggy Layered Bob with a Nape Undercut

Choppy layers all over with a shaved nape underneath. The layers give the top a messy, textured feel, and the undercut keeps the nape from getting heavy, which shag cuts on thick hair tend to do. The shave usually hides under the layers unless the hair is pushed up. Rough-dry with texture spray, scrunch, and leave it. The layers grow out without looking overgrown, which balances the more frequent undercut trims.
