How to find the haircut that actually suits your face (ChatGPT)

Hey, it's Cindy ๐ŸŒฑ You commented HAIRCUT, so here is the whole thing: how to take the one photo that makes this work, the face shape prompt with the follow-ups that matter.
btw the waitlist for AI System Club is now open! If you're keen on using AI to automate your content, video editing, job search, business or build AI agents, feel free to sign up (only if you want to hehe). Ps. the waitlist gets first dibs:)

Nobody ever teaches you this. You pick a cut from a screenshot of someone whose face is nothing like yours, sit down in the chair, and find out an hour later. That is not a you problem, it is a missing-information problem, and it turns out a photo plus a good prompt closes most of the gap. What you are asking for here is not a verdict on your face. It is a read on proportion: where your width sits, where your length sits, and which shapes balance against that.

๐ŸŒฑ Set the frame before you start. There is no such thing as a face that needs fixing, and nothing in this guide treats one that way. Face shape is geometry, the same way a room has a shape. Some furniture suits a long narrow room and some suits a square one, and neither room is wrong.

do this first

Take the one photo that makes this work

The quality of the answer is decided almost entirely here. A dim, filtered, arm's-length selfie gives it the wrong shape to read, and then it confidently describes a face that is not yours.

  1. ๐Ÿ’‡ Pull all your hair back. Off the forehead, behind the ears, no fringe hanging. Your hair is the thing currently hiding your actual outline, which is the only thing being measured.
  2. ๐ŸŒค๏ธ Stand facing a window in daylight. Soft, even, front-on light. Overhead ceiling lights carve shadows under your cheekbones and jaw, and shadows read as bone structure that is not there. Avoid direct sun for the same reason.
  3. ๐Ÿงฑ Plain wall behind you. A busy background makes the outline of your head harder to separate, and the outline is the whole point.
  4. ๐Ÿ“ Do not shoot at arm's length. A phone held close exaggerates whatever is nearest the lens, usually your nose and forehead. Prop the phone up, step back about a metre and a half, and use the timer or the rear camera. This one change fixes more wrong answers than anything else on this list.
  5. ๐Ÿ˜ Neutral face, straight on, eyes level. No smile pulling your cheeks wide, no head tilt, no chin lifted or tucked. Take a second photo in profile too, because the side view is what tells it about your jaw and forehead angle.
  6. ๐Ÿšซ Turn every filter off. Beauty mode, smoothing, face-slimming, all of it. Most phones apply something by default in the front camera, and a slimmed jaw in the photo becomes a slimmed jaw in the answer.

the main prompt

The face shape read

Open ChatGPT (the phone app is easier for uploading photos), start a new chat, attach both photos, and paste this. It works on the free plan. Notice that it asks for reasons, not verdicts: reasons are what let you disagree with it sensibly.

๐Ÿง  read my face shape and give me cuts
I have attached a front-on photo and a profile photo of me with my hair pulled back, taken in daylight. Act as an experienced hairstylist doing a consultation, and work from proportion rather than from compliments.

First, describe what you can actually measure from the photos: the relative width of my forehead, cheekbones and jaw, the length of my face against its width, whether my jawline is soft or angular, my hairline shape, and my neck length. Name my face shape from that evidence and say in one sentence which measurements led you there. If the photo is not clear enough to judge something, say so instead of guessing.

Then give me three haircuts that would balance those proportions. For each one, use the name a salon would recognise, describe the length, the layering and where the shortest pieces would sit relative to my jaw or cheekbones, and explain in one sentence which proportion it is balancing and how. Then give me two cuts to avoid, with the same kind of reason, and say plainly if a cut is only a problem for certain hair textures rather than for my face.

Before you finish, ask me the three things a stylist would ask that you cannot see in a photo: my hair texture and density, how much time I will realistically spend styling it in the morning, and whether I am growing my hair out or cutting it shorter. Then revise your three recommendations based on my answers.
๐Ÿ“Œ Push back on it. If it names a face shape that does not match what you see in the mirror, say so: "my jaw is wider than my forehead, look again at the front photo." It will re-read the image. An answer you argued with is far more useful than the first one it produced.

same photo, more answers

The four follow-ups worth running

You already did the hard part by taking a good photo. These four run in the same chat, which means the model is still looking at the same proportions it worked out above.

โœ๏ธ Brow shape Brows frame the top third of your face and change how wide or long it reads. A small change here is more noticeable than most people expect and it grows back.
๐Ÿ‘“ Glasses frames The most expensive guess on this list, and the easiest to get a useful read on, because frame shape is pure geometry against your face.
๐Ÿ’Ž Earrings and necklines Both sit in the same zone as your jaw and neck, so they either lengthen or shorten the same lines your haircut is working on.
๐ŸŒฑ Colour undertone Warm or cool, which decides whether gold or silver sits better on you and which shades near your face lift you rather than wash you out.
โœ๏ธ brow shape
Using the same photos, tell me what brow shape would suit my face, working from the proportions you already measured rather than from a trend.

Cover the arch (soft, angled or straight), the ideal thickness relative to my features, and where the peak of the arch should sit relative to my eye. Explain each choice by naming which part of my face it is balancing, for example lengthening a rounder face or softening a stronger jaw.

Then tell me what NOT to do to my current brows: which direction over-plucking would take my face, and the one change that would make the biggest difference with the least risk. Keep in mind that brows grow slowly, so rank your suggestions from lowest to highest commitment.
๐Ÿ‘“ glasses frames
Using the same photos, recommend glasses frame shapes for my face, and be specific enough that I could search for them in an optician's website filters.

Give me three frame shapes that work and one to avoid. For each, name the shape (for example round, rectangular, cat-eye, aviator, browline), say how wide the frame should be relative to the widest part of my face, where the top of the frame should sit relative to my brows, and whether the bridge should be low or high for my nose. Explain in one sentence what each shape is balancing.

Also tell me which frame colours would sit well against my hair and skin, and whether a thin metal or a thicker acetate frame suits my features better. Finish with the two-line summary I could read out in a shop.
๐Ÿ’Ž earrings and necklines
Using the same photos, tell me which earring shapes and which necklines flatter my face and neck proportions.

For earrings, cover shape (studs, hoops, drops), scale relative to my jaw, and length relative to my chin, and say which combination lengthens my face and which widens it, so I can pick depending on what I want on the day. For necklines, cover crew, V, scoop, boat and collared shirts, and say which lengthen my neck and which shorten it.

Explain every recommendation by naming the proportion it is working with, and where two options do the same job, say which one is the safer everyday choice and which is the bolder one.
๐ŸŒฑ colour undertone
Using the same daylight photo, read my colour undertone and tell me what it means for the colours I wear near my face.

Say whether I read as warm, cool or neutral, and name the evidence you are using, for example the cast in my skin, the tone of my hair, and my eye colour. Be honest about your confidence level, since screen and lighting conditions affect this a lot, and tell me what a more accurate photo would look like if you are unsure.

Then give me eight specific colours that would lift my face, with a plain-English name and a hex code for each, and four that would wash me out. Finish by telling me whether gold or silver jewellery suits me better and why, and which hair colour direction, warmer or cooler, would sit more naturally against my skin.

before you book

See it on your own face first

Reading "long layers with a curtain fringe" and seeing it on your head are different things. Virtual try-on apps let you check the shape against your actual face before anything is cut or bought.

  1. ๐Ÿ“ฑ Get a try-on app. YouCam Makeup from Perfect Corp is the one I use. It has hairstyle and hair colour try-on plus virtual glasses try-on, free to download with paid extras, on iOS and Android.
  2. ๐Ÿ’‡ Try the three cuts it recommended. Take the actual names from your ChatGPT answer and find the nearest style in the app. You are checking the shape and the length against your face, not judging the app's rendering quality.
  3. ๐Ÿ‘“ Try the frames before you order. Perfect Corp's own rundown of glasses try-on apps covers the alternatives if you want to compare, and many optician sites now have try-on built into the product page.
  4. ๐Ÿ“ธ Screenshot the two you keep coming back to. Two is the number. Ten screenshots in a salon is how you end up with a compromise none of them.
๐Ÿ“Œ Treat a try-on as a preview, not a promise. These apps overlay a style onto your photo, they do not know your hair's density, texture or how it falls. The shape is a fair test, the exact result is not.

the part that matters

Hand it to your stylist properly

The point of all this is not to arrive with an AI printout and tell a professional their job. It is to arrive able to describe what you want in words they use, which is exactly the thing most of us cannot do.

โœ‚๏ธ turn this into a salon brief
Turn your top recommendation into a short brief I can say out loud to my hairdresser, in the language a stylist actually uses.

Write it as five or six spoken sentences covering: the overall shape and length I want, where the shortest layer should sit relative to my jaw or cheekbones, how the front pieces should fall around my face, how much weight to remove and where, and how I want it to sit when I do nothing to it in the morning. Include one sentence about what I do NOT want, phrased politely.

Then give me three search terms I can type into Pinterest or Instagram to find real reference photos of this exact cut on hair like mine, and tell me the one question I should ask my stylist about whether this suits my hair texture, since you cannot judge texture from a photo.
๐Ÿ–ผ๏ธ Bring photos as well as words Two or three references of the cut on someone with a similar hair texture. Texture matters more than face shape for how a cut actually falls.
๐Ÿ—ฃ๏ธ Let the stylist overrule it They can see your growth patterns, cowlicks, density and how your hair behaves wet and dry. If they say a cut will not work on your hair, they are right and the model is guessing.

the honest bit

What this can and cannot tell you

It is an estimate from a flat photo, not an assessment of you. Lighting, angle and lens distortion all change what it reads, which is why two photos of the same person can produce two different face shapes. It cannot see your hair texture, density, growth patterns or how much time you have on a Tuesday morning, and those decide more about a haircut than face shape does. Tom's Guide, who walked through the same idea in their own test, land in the same place: use it to explore, then check with a professional before anything drastic. Perfect Corp's hairstyle analysis explainer is a decent primer on what face-shape analysis is actually doing.
๐ŸŒฑ One boundary worth keeping. If the model starts commenting on your skin, your weight, or anything that sounds medical, close that thread. It is not qualified to say any of it, and neither is any tool of this kind. Ask it about shapes and proportions, which is what it is genuinely useful for, and take anything else to an actual professional.
