Hair Progress Photo Comparison

Make a hair growth before and after comparison: line up two progress photos side by side, with a slider or as an overlay — privately, in your browser.

How the hair growth before and after comparison works

Progress photos are one of the best ways to see a change you can’t feel day to day — but only if the two photos are comparable. This tool puts your before and after pictures into the same frame so the difference is easy to judge, and it does all of that on your own device.

Your photos stay on your device

When you choose a photo, your browser opens it from your phone or computer and shows it in the page. Nothing is uploaded, nothing is stored, and there is no account. Reloading the page clears both photos. When you save a comparison, the image is drawn by your browser and downloaded straight to your device.

Three ways to compare

Side by side places the two photos next to each other with their dates — the clearest view for sharing.
Slider stacks the photos and lets you drag a divider across, so you can check where your ends land against the same strap line or seam.
Overlay fades the after photo over the before photo; at around 50% it is the easiest way to line the two up.

Lining photos up

Photos are rarely taken from exactly the same distance. The alignment controls resize, move and straighten the after photo (up to 10 degrees either way) without changing the before photo. Match a fixed feature — your ears, your part, the top of your shoulders — and the comparison of length becomes much fairer. The saved image uses exactly the same alignment you see on screen.

What photos can and can’t show

A hair growth before and after comparison is only as good as the photos. Shrinkage, humidity, posture and camera height can all make the same hair look longer or shorter, so use the checklist below and pair your photos with tape-measure numbers in the length retention tracker. Photos are also not a way to judge hair loss — thinning areas, bald patches or a sore scalp are a reason to see a dermatologist.

Checklist for consistent progress photos

Keep the same	Why it matters	How
Light	Shadows hide length and highlights make hair look thinner or lighter.	Face the same window at the same time of day, or use the same lamp. Skip the flash.
Angle and distance	A camera held lower makes hair look longer; closer makes everything bigger.	Have someone stand in the same spot, or prop the phone at shoulder height on a shelf and use the timer.
Hair state	Coily hair can shrink by half or more, and a fresh twist-out reads shorter than stretched hair.	Photograph the same state every time — straightened, banded or stretched, or always on day 2 of a wash-and-go.
A length marker	You need a fixed point on your body to judge progress.	Wear the same fitted top or bra each time so the strap line, shoulder seam or waistband shows where your ends land.
Posture	Tilting your head back makes hair look longer.	Stand straight, chin level, arms relaxed at your sides.
Camera settings	Portrait mode, beauty filters and wide-angle lenses change shapes and edges.	Use the main lens with filters off. Keep the same phone if you can.

Take a photo every month on the same day, and compare photos at least three months apart for a clear view of change.

Frequently asked questions

How do I take hair growth progress pictures?

Use the same light, the same spot and the same camera height every time, photograph your hair in the same state (stretched or styled the same way) and wear a top that marks your shoulders or bra-strap line. Take a back view and, if you like, both sides. The checklist below covers the details.

Are my photos uploaded anywhere?

No. Your photos are opened directly in your browser and never sent to our servers or anyone else. They disappear when you close or reload the page. The comparison image you save is created on your device too.

How often should I take hair progress photos?

Monthly photos are plenty, and comparing photos three or more months apart shows change most clearly, because hair grows slowly and small differences are hard to see.

Why does my hair look shorter in my newer photo?

Usually because of how the photo was taken: a different hair state (shrinkage), a higher camera angle, humidity, or posture. A trim or breakage can also take off length. Compare photos taken the same way, and back them up with tape-measure numbers in the length tracker.

Can I compare photos taken with different phones or distances?

Yes. Open “Line up the after photo” to resize, move and straighten the second photo until your ears, part line or shoulders match. Overlay mode at about 50% makes alignment easiest.

Which comparison view should I use?

Side by side is best for sharing. The slider is best for checking where your ends land against the same point on your back. Overlay is best for lining photos up and spotting small differences.

Which photo formats work?

JPG, PNG and WebP work in every modern browser. HEIC photos from iPhones open in Safari; in other browsers, export them as JPG first or set your camera to “Most Compatible”.
