Thinning Crown Test
A thinning crown test for the spot you can't watch.
The crown is a blind spot — diffuse thinning there often spreads for months before a single photo catches it. Two guided angles put that whole area on record, read coverage as stable tiers, and keep a baseline so the only question that matters — has it moved? — finally has a fair answer.

How it works
Four photos. One baseline. Every change tracked.
Same four angles, every time — so each new scan compares fairly to your very first.
Front · crown · temple · back
Capture
Four guided angles in about 30 seconds — the same views every time.
Hairline · density · scalp
Read
AI reads each angle for hairline shape, crown density, and scalp surface.
Usable · limited · low-light
Qualify
Every reading shows its confidence — limited views are flagged, not guessed.

What the crown test reads
Coverage across the whole crown — not just the swirl.
Four reads built around the one area of your head you physically can't watch yourself.
Crown coverage
How full the crown reads under even light, across the whole area — the diffuse show-through a quick glance misses entirely.
Swirl vs. thinning
The swirl can look sparse without being thin. The test reads the area around it as a tier, so anatomy isn't mistaken for change.
Top and back together
Two angles cover the crown so the edge of any spreading area isn't cropped out of the story.
Honest about light
Crown photos are light-sensitive. Overexposed or dim views lower the confidence shown — they aren't guessed over.
Test it like a trend
Two crown photos beat two hundred mirror glances.
Diffuse crown thinning shows up across months, not minutes. The test is built to catch the direction.
Capture the blind spot
Guided top and back angles with fixed framing — no contortions with a hand mirror, no relying on one unflattering photo from last weekend.
Read coverage as a tier
Crown coverage comes back as a stable qualitative tier with its confidence — comparable between scans, not a one-off impression.
Re-test in 8–12 weeks
Compared against your own saved baseline on identical angles, so a moved tier is a real change on your head — not a lighting day.
Read direction, calmly
If coverage is dropping you'll see it early; a flat, stable trend is a perfectly good answer too — and one worth having.
Questions
Good to know.
How do I test for a thinning crown at home?
Without a second mirror you mostly can't see your own crown — it sits in a natural blind spot. A guided top-and-back scan photographs the whole area the same way each time and reads visible coverage as a tier, which is what makes the test repeatable instead of a one-off guess.
How is this different from the bald spot checker?
The bald spot checker is for a specific spot you've already noticed; this test reads diffuse thinning across the whole crown — the gradual, even kind that's hardest to spot in a mirror. Same scan underneath, but the crown test is built to answer direction over time.
Is my crown actually thinning, or is it just the swirl?
Every crown has a swirl where hair fans out around a centre, and it can read sparse without being thin. The test reads coverage across the whole crown area rather than the swirl point, and a rescan shows whether it's stable anatomy or spreading show-through.
How often should I re-test the crown?
Every 8–12 weeks is plenty. Visible crown change is slow and light-sensitive, so comparing identical top angles a few months apart tells you far more than frequent mirror checks ever will.
Is the result a diagnosis?
No — it's an appearance-based read for tracking. If thinning appeared suddenly or looks patchy, that's a see-a-qualified-professional situation rather than a tracking one, and dated photos make that conversation better.
A note on transparency
Informational and cosmetic — not a diagnosis.
ScalpAnalysis AI reads appearance-based signals and tracks visible change over time. It does not diagnose, treat, cure, or prevent any condition.
If you have pain, sudden shedding, or signs of infection, a qualified professional is the right next step.
