Hairbook is an iPhone app for people on hair-loss treatment. Tick off every dose, take progress photos that line up with the last ones, and bring a clear record to your doctor.
Made with ❤️ by someone on treatment, for people on treatment.
Finasteride, minoxidil, PRP or a transplant: most treatments take months before anything shows. Bad lighting and a new angle can make a good month look bad. Hairbook makes every photo comparable and every dose countable, so you're judging real progress, not a bad mirror.
Three things you'll do in the app. Go ahead, they work just like the real thing.
Your last photo shows faintly over the camera. Match it, shoot, then drag, pinch and rotate until it sits exactly on top.
Put any two sessions side by side, slide between them or blend them. Hairbook never scores your photos. You decide what you see.
3 doses left today
Add the treatments you already take. Reminders stop once a dose is ticked, and the streak forgives one missed day a week.
Hair-loss treatment runs for months before change is visible. Hairbook keeps what you need to remember, and shows you how it's going.
Add your tablets, topicals and supplements with your own doses and times. Today shows what's due, and a tap logs it.
Each session covers five angles: front, left, right, top and crown. You choose how often, from weekly to every six months, and Hairbook reminds you when one is due.
Insights shows how many doses you took on time, week by week, with an adherence calendar for each treatment. Short check-ins record shedding, scalp, mood and side effects on a schedule you set.
Your progress photos never touch our servers. They're stored only on your iPhone and never uploaded anywhere.
One tap turns what you've logged into a clean two-page PDF your doctor can read in a minute. Share it, print it or bring it on your phone.

Hairbook is an iPhone app for people on hair-loss treatment. It keeps your doses, progress photos, check-ins and lab results in one place, so you can follow your treatment over months.
Your last photo from the same angle shows faintly over the camera, so you can match the angle. After you take the photo, you can drag, pinch and rotate it to line it up exactly with the last one before saving. Each session covers five angles: front, left, right, top and crown.
No. Hairbook does not score or measure your photos. You compare any two sessions yourself, with a slider, side by side or blended.
Any treatment you already take. You add your own tablets, topical treatments and supplements, with your own doses and times. Hairbook never chooses or recommends a treatment.
No. Hairbook is a tracker. It does not diagnose, treat or recommend treatment. Talk to your doctor about your treatment.
Your progress photos never touch our servers. They are stored only on your iPhone and never uploaded, to our servers or to iCloud. They are part of your iPhone backup, so setting up a new iPhone from a backup brings them with you. Your other records are kept in a private area of your account and sent over encrypted connections. You can add a Face ID lock and delete everything from Profile.
If you join before Hairbook launches on the App Store, it is free for life. After launch, new users get a 7-day free trial and then a subscription through the App Store, yearly or monthly, which you can cancel at any time. There are no ads.
Hairbook is in TestFlight now and coming soon to the App Store for iPhone.
I started hair-loss treatment in 2026 and couldn't find a tracker that kept my doses and photos together and stayed private. So I made one. Hairbook is the app I use every day, and I hope it helps you stay on track too. ❤️
Designed and built by one person, with Claude Code as an engineering partner.
