AI bob haircut simulator

A bob works with the jaw rather than around it. Because the ends stop somewhere near the widest part of the lower face, they act like a bracket that draws attention to that line, and the effect changes with where exactly you stop.

If your jaw is soft or rounded, a bob that ends just below the jaw gives the lower face a defined edge it does not have on its own. If your jaw is already strong and square, the same length underlines it, so most stylists will either drop the length past the jaw or angle the front forward to soften the corner.

Hair texture matters at least as much as face shape here. Fine hair usually gains from a blunt bob, because ending every hair at the same point makes the perimeter read as thicker than the same hair cut into layers. Thick hair usually needs internal layers or it will build width at the ears and sit out in a triangle. Curly hair needs the cut planned around shrinkage, which is a different conversation entirely.

This is a short version on purpose. The full picture, face shape by face shape, is in the guide linked above.

One practical note before you book. A bob changes how much of your neck and jaw is on show, and that is the part people react to most in the first week. If you have never had hair above the shoulders, the render is worth running twice: once at collarbone length and once at the jaw, so you can see the size of the jump rather than guessing at it.

The single biggest thing you control is your wording. Short hair is not a description, it is a category, and the model will pick something generic from the middle of it.

Describe three things and you will get a usable render nearly every time.

Where it ends. Chin-length, jaw-length, collarbone, just below the ear. Use a body landmark rather than a measurement, because inches mean nothing without knowing your proportions.

How blunt the ends are. Blunt, one clean line, softly point-cut, or internally layered. This is what makes a bob read heavy or light, and it is the thing people most often forget to say.

Which way it angles. Level all the way round, graduated shorter at the back, or sloped longer at the front. A bob and an angled bob are genuinely different cuts and the word angled is what separates them.

A prompt like chin-length blunt bob with a slight forward graduation will give you something far closer to what you pictured than bob. If the first render is not right, change one word and try again rather than rewriting the whole thing.

It is worth being straight about this, because a preview that oversells itself is worse than no preview.

Reliable. Outline and proportion. Where the ends fall against your jaw, chin, and shoulders. How much of your face the cut leaves visible. Whether the width sits at your ears or below them. Roughly how a fringe changes the space between your brows and hairline. These are the questions a bob decision actually turns on, and they are the ones the render answers well.

Approximate. Fine strand detail and the exact way your ends separate. Colour under salon lighting, which is different again from your bathroom mirror. How much volume you would get on a good blow-dry versus air-drying.

Not modelled at all. Your growth pattern. A cowlick, a strong natural parting, or a whorl at the crown will fight a cut that the render shows sitting perfectly flat. Density changes down the length. What your hair does on day three. And crucially, your stylist's own interpretation, which is a bigger variable than any of these.

Use it to rule things out. A shape that looks wrong in the render is very unlikely to be right in the chair, and that is genuinely useful information before you have paid for anything.

Bring the render, but do not bring only the render. A stylist needs to see a real finished head of hair to understand the texture and finish you are after, because an AI preview shows shape without showing how the cut was executed.

The combination that works is your render plus one or two photos of a real bob on hair similar to yours in texture and density. The render answers does this shape suit my face. The real photo answers this is the finish I want. Together they close most of the gap that causes disappointing appointments.

Say out loud where you want the ends to sit, using your own face as the reference. Touching your jaw and saying here is more precise than any adjective. Ask directly whether your hair will do what the photo shows, and listen to the answer. A stylist who tells you your hair is too fine to hold that blunt line is giving you the most valuable thing in the appointment.

Ask about upkeep before you sit down, not after. A chin-length bob needs trimming every six to eight weeks to keep its line, and that is a standing commitment worth knowing about in advance.

Finally, book the consultation separately from the cut if the salon offers it. Ten minutes with a stylist and your render, a week before the appointment, is the cheapest insurance available against walking out with a bob you did not want.
