RETAIN
A measuring instrument for hair loss

Know whether it's working.

Four guided photos give you one score, tracked over months. Retain won't regrow your hair. It tells you the truth about what is happening to it.

This is the real app, running on example data
01 / SCAN

Four angles, taken the same way every time.

Consistency is the whole product. A score you can't repeat means nothing.

Four angles
Hairline, crown, both temples.
Auto-fire
Shots trigger at the right pose. No shutter button to fumble.
Strict
A photo it can't read is rejected, not guessed at.
10 seconds
One slow turn. That's the whole scan.
02 / READ

It names what it sees, in plain words.

Where the thinning is, never why. Retain describes; it does not diagnose, and it never tells you what to take.

Front
The hair up front is thinner than the rest. You can see it most in bright light.
Temples
Both sides are thinning. This is where it usually shows up first.
Crown
Looks full. Nothing to watch back here.
Norwood 3
The scale insiders use, when the pattern fits it. A map, not a grade.
03 / LOG

One tap a day for what you actually did.

It takes about five seconds. The streak is the part you control, which is why the daily win lives there and not in the score.

One tap a day
That's the whole job.
Streaks
The part you control.
Full names
Finasteride, not abbreviations you have to decode.
04 / THE WAIT

A flat line is a result.

Hair loss doesn't pause on its own. A line that stays flat means your routine is holding it there. Retain calls that what it is: a win.

05 / VERDICT

Then it answers the question.

Where it moved, where it held, and whether your routine is what moved it. One answer, on a schedule slow enough to be true.

Working
A clear gain, beyond what the instrument can wobble.
Holding
With hair, that's a win.
Slipping
Caught early, and said calmly.

Nothing has moved further than a scan can wobble. Most untreated hair drifts the other way, so holding steady is the routine doing its job.

The free plan is real.

One scan a month, your score, your photo timeline, and a card a week on what is actually happening while you wait. It does not expire, and there is no trial that quietly turns into a charge. Paying adds the part that connects cause to effect: where on your head it changed, and whether your routine is what moved it.
