Bald Spot Checker
The spot you can't see is the one worth checking.
Crown thinning happens in your blind spot — most people first hear about it from a photo someone else took. The top and back angles of a guided scan put that area on record properly: how it looks, how it reads, and whether it changes.

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.

Save it, rescan later, and see exactly what moved.
What the crown check reads
Coverage, swirl, and the honest difference.
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 — the show-through signal a quick glance exaggerates or misses entirely.
Swirl vs. thinning
Every crown has a swirl that can look sparse without being thin. The check reads the area around it, not just the point.
The back view too
A second angle from below the crown, so the edge of any visible spot isn't cropped out of the story.
Honest about light
Crown photos are light-sensitive. Overexposed or dim views lower the confidence shown — they don't get guessed over.
From party photo to answer
From “what was that in the photo?” to a tracked answer.
Capture the blind spot
Guided top and back angles — 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.
Separate swirl from signal
A visible swirl is anatomy; spreading show-through around it is a trend worth watching. Repeat scans tell them apart.
Rescan under the same rules
Identical angle and framing on every check — if anything grows, you'll see it in the comparison, early.
Questions
Good to know.
How do I check a bald spot at home?
Without a second mirror or someone else's phone, you mostly can't — the crown sits in a natural blind spot. A guided top-and-back scan photographs it the same way every time, which is what makes checking it repeatable.
Is the spot I'm seeing just my crown swirl?
Possibly — every crown has a swirl where hair fans out around its centre, and it can read sparse without being thin. The check reads coverage across the whole crown area, and a rescan shows whether it's stable anatomy or spreading show-through.
Can it measure the size of the spot?
It reads visible coverage as qualitative tiers rather than centimetres — that's what a phone photo can honestly support. What it's built to answer is direction: stable, or more show-through than your baseline.
Why does my crown look worse in some photos?
Harsh overhead light and flash exaggerate show-through; soft, even light hides it. Guided capture keeps conditions consistent, and low-quality views lower the reading's confidence instead of inflating the result.
Is this a diagnosis?
No — it's an appearance-based read for tracking. If a spot appeared suddenly or looks patchy, that's a see-a-professional situation rather than a tracking one.
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.

This is the exact report format a scan unlocks — qualitative tiers, your visible features, and a confidence level on every reading. Saved as a baseline you compare against on every rescan.
