Hairy

A hair journal for iPhone.

Hairy is a private journal for tracking your hair over time. You photograph the same five angles in each session, and the app keeps the record so you can look back at any point and see what has actually changed.

It is built by Grovy Health Inc.

What it lets you do

1. Log photo sessions every day.
2. See how you look over time with a longitudinal view that normalizes the positioning and framing of your photos from each of the different angles.
3. Get insights on how your hair quality and recession are doing, based on specific metrics.
4. Log your routines and keep track of your habits.

How a session works

A session is five photos, taken from the same five angles each time: front, front pulled back, right profile, left profile, and crown. On-screen guides help you line each shot up with your previous session, so the comparison holds.

Sessions are yours to take whenever you want. Most people settle into a weekly rhythm, but nothing is locked to a schedule.

Insights

You can ask Hairy to read a session. It produces a set of metrics covering hair quality, recession, graying, and scalp condition, along with written notes describing what it sees. Readings are compared against your own history rather than against anyone else, and they are observations, not medical advice or a diagnosis.

Routines

Alongside the photos you can log what you are actually doing — washes, conditioners, treatments, medications, and supplements — so that changes you see in the journal can be lined up against the habits behind them.

Availability

Hairy is in private beta on TestFlight for iPhone, and is coming to the App Store. If you would like to hear when it opens up, email team@hairy.app.
