A hair-loss treatment tracker, built by someone on treatment

I'm losing my hair. So I built the app I wanted.

Hairbook keeps the whole treatment in one place: the doses you take, photos that line up from one session to the next, check-ins and lab results. So in six months you can answer the only question that matters: is it working?

Why I built it

I'm Hammad, an iOS engineer. Most men deal with hair loss at some point, and this year it was my turn. I saw a doctor and started treatment in October 2026.

The hard part turned out not to be the treatment. It was everything around it. Hair changes too slowly to see in the mirror. My photos never matched, because the angle and the light were different every time. I could not remember whether I had taken last night's dose. And when my doctor asked how the last three months had gone, I had nothing to show.

I looked for an app that handled this properly and did not find one I trusted with photos of my own scalp. So I built it, and I use it every day. Hairbook is that app.

What it does

Never wonder if you took it

Add your own treatments and times. Tick each dose, get a reminder that stops once you have, and keep a streak that forgives one slip a week.

Photos that line up

An outline of your last photo sits over the camera, so every shot is taken from the same angle and distance.

See what is changing

Slide between any two sessions and watch months of slow change become visible.

Something to show your doctor

Check-ins, lab results and a one-tap report with your regimen, adherence and photos.

A moment for you

Finish your doses and take a quick selfie. Treatment is slow; a record of showing up helps on the days it feels pointless.

Private by design

Your photos and records sit in your own account, and only you can open them. No ads, and nothing is sold.

Where it is going

You are not the only one

The next step is a community: a place to compare notes and share progress with people on the same path, on your terms and only if you want to.

How it is built

Hairbook is built by one person. I designed and wrote it as a native iOS app with Claude as my engineering partner, from the first screen to the test suite. That is how a solo founder ships something this complete: the app is in TestFlight today, with subscriptions, offline support and widgets already in place.

The first 100 customers get lifetime access, free. After that it is a simple subscription with no free tier and no ads.

Hairbook is a tracker. It does not diagnose, treat or recommend treatment. Talk to your doctor about your treatment.
