Published 2026-09-26 · Last updated 2026-09-26 · By Jack Stovell (https://i.hilyt.it/jack) · Canonical page: https://howtogetaito.com/try/a-new-hairstyle/ ## What you'll be able to do Right, so here's the thing about hair. You can't try it on like a jumper. You either commit to the chop or you don't, and that gap between "what if" and "actually done" is where most people just... freeze. Anyway, this guide is about closing that gap a bit. By the end you'll be able to see a fringe, a bob, or a completely different colour on your own actual face, using either a proper try-on tool or a general AI assistant editing your own photo. You'll also come away with something a hairdresser can actually work from, which honestly might be the more useful bit. ## Before you start A try-on preview is not a guarantee. I want to say that early because it matters more than anything else in this guide. What it can show you: roughly how a length or a fringe line sits against your face, whether a colour family suits your skin tone, whether you'd hate a style before you've paid anyone to do it. What it cannot show you: how your actual hair, with its actual thickness and its actual curl pattern, will behave once someone's cut into it. A screen can put platinum blonde on jet black hair in one tap. Real hair can't do that without a lightener or bleach, and very dark hair often can't do it in one sitting either. The photo you use matters more than people expect. Front-facing, even light, no hat, no glasses, hair pulled back off your forehead and jawline so the tool can actually see where your hairline is. Bad light or hair falling over your face and you'll get a preview that looks like a smudge wearing a wig. ## Get set up There are two kinds of tool here, and they do different jobs, so it's worth knowing which one you actually want. The first is a dedicated try-on: something built specifically for hair, with preset cuts or shades you map onto a photo or live camera feed. YouCam's Online Editor (the AI Hairstyle Changer, from Perfect Corp) runs right in your browser, no download needed. Upload a photo, pick from separate men's and women's collections organised into tabs like Bangs, Wavy, Volume, or use "Upload Hairstyle" to bring in a reference photo of a cut you like. Your result sits next to the original so you can compare properly. It's free for a couple of full previews after you sign up, no card needed, though more than that needs credits or a subscription (worth checking the current page, since these things shift). YouCam's own FAQ is honest about the limits too: it calls the result a styling reference, not a guarantee, because hair thickness and the stylist's technique change everything. There's also a YouCam Makeup app for iOS and Android with hairstyle and colour try-on built in. For colour specifically, the big haircare brands have their own tools. L'Oréal Paris UK's Hair Colour Try On (built on ModiFace tech) lets you use live camera or a selfie upload, pick a colour family, and compare before and after. It's upfront that live and selfie images are never stored, and that results vary depending on your actual hair colour and condition. Garnier UK has a similar Virtual Try-On, with a roots-only mode if that's all you're after, plus a Color Match quiz for checking whether a shade you like will actually work on your hair. Both work with your phone or computer camera, or a selfie you upload. Worth knowing: both of these only show you that brand's own shades, and only colour, not cuts. Fair enough, they're selling dye. Then there's the second route: general AI assistants like ChatGPT or Gemini. These aren't built for hair specifically, they'll edit any photo based on however you describe the change. ChatGPT Images (the current version is 2.5) sits across every tier, on web, iOS and Android. You upload a photo and describe what you want changed, or use the selection tool to point at exactly where. OpenAI's own guidance says highlights aren't always precise and edits can spread beyond the bit you selected, so don't be shocked if your fringe edit nudges your eyebrows slightly. Gemini works similarly: upload a photo and ask for edits, using what Google calls Nano Banana 2, though editing images is only for users 18 and over. Which one should you use? Honestly, if you just want to see "would a bob suit me" fast, the dedicated try-ons are quicker, because you're picking from a menu rather than writing anything. If you want something specific worded out, like a very particular fringe length with your natural texture kept intact, a general assistant with a proper prompt gets you closer. ## Try it yourself Here's where you actually do it. Upload your photo (front-facing, good light, hair pulled back, remember), and depending on your tool, either pick a preset style or write out exactly what you want. If you're using a general assistant like ChatGPT or Gemini, the prompt is doing all the work, so it needs to be specific. Here's one for a cut: ``` This is a photo of me. Change only my hair to a chin-length bob with a soft side fringe. Keep my face, skin, expression, clothes and background exactly as they are. Keep my natural hair texture, which is [wavy/straight/curly/coily]. Do not smooth my skin or change my face shape. ``` For colour, the honest framing matters just as much as the request itself: ``` Same photo, same haircut I have now. Change only the colour to [shade], the way it would realistically look on [my current colour] hair. If it would take bleaching or several sessions, say so under the image. ``` That second one is worth pausing on. If you're going from dark to much lighter, L'Oréal's own guidance says you'll usually need a lightener or bleach, very dark hair might take several gradual stages, not one sitting, and warm red or orange tones showing through as you lift the colour is completely normal, not a mistake. A good prompt makes the AI say this out loud rather than just showing you a flattering lie. If you're using YouCam or a brand try-on instead, there's no prompt as such, just pick your style or colour from the collection and let it run. Do try the same style across two different photos, or even two different tools, before you trust what you're seeing. More on that in a second. Now the bit that actually gets you a good haircut. The preview is a conversation starter, not an instruction. Take it to your hairdresser, but take real photos too: pictures of the cut on actual people whose hair is like yours, same sort of thickness, same texture. A cut that looks great on thick straight hair behaves completely differently on fine curly hair, and a real photo shows that where a generated one hides it. Then ask what your hair can realistically do and how much upkeep it'll need. This prompt turns your chosen preview into words a hairdresser can use: ``` I'm taking this picture to my hairdresser. Describe the cut in words they would use: length at the front and back, layers, fringe, parting, and how it is styled. Then list five questions I should ask about whether my [fine/thick, straight/curly] hair can do this and how much upkeep it needs. ``` And a word on face shape. Plenty of tools, YouCam's quiz included, ask whether your face is round, square, oval or heart-shaped and suggest cuts from that. It's a reasonable place to start, not a rule, and your hair type and how you actually live matter just as much. If you've narrowed it down to a few options, this gets you an honest second opinion: ``` Here is my current photo and three hairstyles I'm considering. For each, tell me honestly what might not work with my hair type and face, and what to ask a hairdresser. Treat face-shape rules as a starting point, not a verdict. ``` ## Check the result Right, so the preview's landed. Before you get attached to it, run a few checks. Put it side by side with your real photo, same size, not one zoomed in more than the other. Look at the hairline: does it sit where your actual hairline sits, or has it drifted? Check the parting, the ears, whether the fringe edge looks like hair or looks like it's been stuck on with a ruler. Colour should look like hair, with some natural variation and shine, not like an Instagram filter laid flat across the top. Then the real test: would this work with your actual texture, and how you style it on an ordinary Tuesday morning, not some idealised salon-blowdry version of your hair? A pin-straight bob preview means very little if your hair is naturally curly and you're not planning to straighten it every day. Try the same request on two separate photos of yourself, and ideally across two different tools. If the fringe line and the colour tone stay roughly consistent, you can trust the shape of what you're seeing a bit more. If they wildly disagree, that tells you something too, mainly that you're looking at a rough guess, not a precise forecast. ## If it doesn't work Sometimes it just looks off. Hair that looks painted on, edges that bleed into the background, colour that sits like a sticker rather than actual strands. Usually this comes down to the photo, not the tool: retake it with better, more even light, hair pulled back properly, and try again before you give up on the whole thing or switch tools out of frustration. Sometimes the AI changes more than your hair, your face shape shifts slightly, your skin gets smoothed, your expression goes a bit generic. If that happens, tell it directly: keep my face, change only the hair. Or switch to a dedicated try-on tool: YouCam's colour changer, for one, says it isolates your hair from your face and background so only the hair changes. And sometimes your hairdresser looks at the picture and says no, that won't work on your hair. Believe them. They're looking at your actual strands, your actual scalp, your actual growth pattern, not a flattened photo. On privacy: your face counts as personal data. Only ever upload your own face, never a friend's, never a child's. YouCam's hairstyle page suggests you could use a friend's selfie as a style reference; don't upload anyone's face without asking them first. Where you can, use a reference photo of just the hairstyle rather than a face at all. YouCam keeps Online Editor uploads temporarily, deleted after 30 days, though it says a few features retain files while your account stays active, clearly flagged where that applies. Its privacy policy counts your face geometry as biometric information, says it doesn't use facial recognition to identify people, and says its services aren't meant for under-13s. L'Oréal Paris says its try-on never stores your live or selfie images; Garnier's try-on page doesn't say either way, so read the L'Oréal UK privacy policy its site links to, which covers virtual try-on, before uploading a selfie. In ChatGPT, turn off "Improve the model for everyone" so new chats aren't used for training, and delete an image by deleting the whole conversation it lives in. Google treats a photo you upload to Gemini like any other prompt, and chats picked for human review can be kept for up to three years. On a linked teen ChatGPT account, a parent may be able to control whether the teen can create or edit images at all. Delete whatever you don't need once you've made your decision. If you're planning an actual colour change, one more thing that has nothing to do with AI. Many permanent and some semi-permanent dyes contain PPD, which can irritate skin or cause an allergic reaction. The NHS says to test the dye at least 48 hours before you use it and follow the instructions on the pack; reactions can take up to 72 hours to appear, having had a black henna tattoo raises your risk, and if you react, don't use the dye. L'Oréal Paris calls this an allergy alert test, 48 hours before, and also suggests a strand test at the back of your head to see how the colour will actually turn out. None of the apps in this guide can tell you whether your skin will react. Only the test can. And for teenagers wanting a change: home hair dyes made with the usual oxidative dye ingredients have to carry the UK label warning "This product is not intended for use on persons under the age of 16." Trying a colour on screen is one thing (check the tool's age rules first: Gemini's image editing is 18 and over, YouCam isn't for under-13s); the box dye is a different question, so talk to a hairdresser first. ## Questions people ask ### Is an AI hairstyle try-on free? YouCam's Online Editor is free for a couple of full previews after you sign up, with no card needed; more than that needs credits or a subscription, so it's worth checking the current page as these things shift. ### Which AI tool is best for trying a new hairstyle? Dedicated try-ons like YouCam's AI Hairstyle Changer are quicker if you just want to see whether a bob would suit you, because you pick from a menu. For something specific, like a particular fringe length with your natural texture kept, a general assistant such as ChatGPT or Gemini with a proper prompt gets you closer. ### What kind of photo works best for a hairstyle try-on? Front-facing, even light, no hat, no glasses, and hair pulled back off your forehead and jawline so the tool can see where your hairline is. Bad light or hair falling over your face gives you a preview that looks like a smudge wearing a wig. ### How do I know if the AI hairstyle preview is any good? Put it side by side with your real photo at the same size and check the hairline, parting, ears and fringe edge, and whether the colour has natural variation and shine. Then try the same request on two photos and ideally two tools: if they wildly disagree, it's a rough guess, not a forecast. ### Is it safe to upload my selfie to a hair try-on tool? Your face counts as personal data, so only ever upload your own face, never a friend's or a child's. YouCam keeps Online Editor uploads temporarily, deleted after 30 days, and L'Oréal Paris says its try-on never stores your live or selfie images. ## Keep exploring If you're thinking about the whole look rather than just the hair, there's a guide on this site called "[How to get AI to help me choose what to wear](https://howtogetaito.com/help-me/choose-what-to-wear/)" that covers similar ground for outfits. If you want to go further with general photo editing beyond hair, "[How to get AI to edit a photo](https://howtogetaito.com/edit/a-photo/)" walks through the broader version of what we've done here. And if what you're actually after is a polished portrait rather than a hairstyle test, "[How to get AI to make me a headshot](https://howtogetaito.com/make/a-headshot/)" covers that separately, including why it's worth showing the result to someone who knows you before you use it anywhere. ## Sources and review notes - YouCam Online Editor, AI Hairstyle Changer (features, free previews, photo tips, realism FAQ): https://yce.perfectcorp.com/ai-hairstyle-generator - YouCam Online Editor, AI Hair Color Changer (hair detection, dark-to-light FAQ): https://yce.perfectcorp.com/products/hair-color-changer - YouCam Online Editor FAQ (uploads deleted after 30 days): https://yce.perfectcorp.com/faq - YouCam Makeup app: https://www.perfectcorp.com/consumer/apps/ymk - YouCam B2C Privacy Policy (biometric information, under-13s): https://www.perfectcorp.com/perfectbeauty/youcam/privacy-policy - L'Oréal Paris UK, Hair Colour Try On: https://www.loreal-paris.co.uk/service-detail-pages/hair-colour-try-on-detail-page - L'Oréal Paris UK, How To Lighten Dark Hair: https://www.loreal-paris.co.uk/how-to-lighten-dark-hair - L'Oréal Paris UK, Hair Colour How It Works (allergy alert test, strand test, warm tones on lifted dark hair): https://www.loreal-paris.co.uk/hair-colour-how-it-works - L'Oréal UK privacy policy (covers virtual try-on): https://www.loreal.com/en/uki/pages/group/privacy-policy-uki/ - Garnier UK, Hair colour Virtual Try-On: https://www.garnier.co.uk/virtual-try-on - OpenAI Help, Images in ChatGPT: https://help.openai.com/en/articles/11084440-images-in-chatgpt - OpenAI Help, Data controls in ChatGPT: https://help.openai.com/en/articles/7730893-data-controls-in-chatgpt - Gemini Apps Help, Generate and edit images: https://support.google.com/gemini/answer/14286560 - Gemini Apps Privacy Hub: https://support.google.com/gemini/answer/13594961 - NHS, Hair dye reactions: https://www.nhs.uk/conditions/hair-dye-reactions/ - UK Cosmetics Regulation, Annex III (hair dye label warnings): https://www.legislation.gov.uk/eur/2009/1223/annex/III Review date: 26 September 2026 — every source above was opened and checked against the text on that date.
