How to try on hair color on your photo before you dye it

By Firchain AI · October 24, 2026 · 6 min read

A new hair color is exciting, and a little scary. Would blonde suit me? Will copper wash me out? What if I hate it? Dye doesn't come with an undo button: fixing a color can take several salon visits and a toll on your hair.

That's why more people try the color on a photo first. This guide shows you how to do it well: which photo to use, what to look for in the result, what an app can't tell you, and how to bring your test to your stylist.

Why test a color before the salon

Step 1: pick the right photo

We cover it in detail, with examples, in how to take a selfie to try on hair color; here are the essentials.

The test is only as good as the photo. To help the app find your hair and make the color look real, use a photo that is:

Step 2: try a range, not just your dream shade

The color you love on someone else isn't always the one that suits you best. Try your favorite, then a shade lighter, a shade darker, and one from a different family:

Sometimes the winner is a color you never would have considered. Not sure where to start? See what hair color suits your skin tone.

Step 3: what to look for in the result

Go beyond "I like it" or "I don't." Check:

  1. Your skin. Does it look brighter or duller? Do dark circles or redness stand out more? A good color makes your skin look rested.
  2. Your eyes and brows. A color far from your brow color can look off. If you still love it, mention it to your stylist.
  3. Contrast. People with high natural contrast (fair skin and dark hair, for example) often carry bold colors well; with low contrast, softer shades tend to flatter.
  4. The full-screen view. Look at the result up close, then from a distance, the way someone across the table would see you.

A tip: save your top two or three and look at them again the next day. The one you still like with fresh eyes is usually the right call.

What an app can't tell you

A photo test is a great help, but it's an approximate preview. Some things only show up on your real hair:

Use the test to choose a direction, and settle the details with your stylist.

Step 4: bring the test to your stylist

  1. Save or screenshot your photo with the chosen color.
  2. Show it next to your original photo, so they can see your starting point.
  3. Ask whether it can be done in one session, whether you'll need bleach and how much upkeep it takes.
  4. If they suggest a similar shade, try that one in the app too before you decide.

How to do it with LookAI

Frequently asked questions

Can I see how a hair color looks on me before dyeing? Yes. A hair color try-on app like LookAI finds your hair in a selfie and applies the shade you pick, so you can compare before and after side by side before you book the salon.

Will the salon result match the app? Not exactly. It is an approximate preview: the real result depends on your starting color, the condition of your hair, whether you need bleach and your stylist's work.

What photo works best for a hair color try-on? A front-facing selfie in natural light, with your hair down and visible, no beauty filters and no hat.

Is it safe to use my selfie in a hair color app? It depends on the app. LookAI runs its AI on your phone and never uploads your photo to a server. With other apps, check the privacy policy.
