Bald Spot Checker
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
Same four angles, every time — so each new scan compares fairly to your very first.
Top · Crown
Side · Temple
Back
Front · Hairline
Same four angles, every time — illustrative example
Front · crown · temple · back
Four guided angles in about 30 seconds — the same views every time.
Hairline · density · scalp
AI reads each angle for hairline shape, crown density, and scalp surface.
Usable · limited · low-light
Every reading shows its confidence — limited views are flagged, not guessed.
Your baseline, revisited
Save it, rescan later, and see exactly what moved.
What the crown check reads
Four reads built around the one area of your head you physically can't watch yourself.
How full the crown reads under even light — the show-through signal a quick glance exaggerates or misses entirely.
Every crown has a swirl that can look sparse without being thin. The check reads the area around it, not just the point.
A second angle from below the crown, so the edge of any visible spot isn't cropped out of the story.
Crown photos are light-sensitive. Overexposed or dim views lower the confidence shown — they don't get guessed over.
From party photo to answer
Guided top and back angles — no contortions with a hand mirror, no relying on one unflattering photo from last weekend.
Crown coverage comes back as a stable qualitative tier with its confidence — comparable between scans, not a one-off impression.
A visible swirl is anatomy; spreading show-through around it is a trend worth watching. Repeat scans tell them apart.
Identical angle and framing on every check — if anything grows, you'll see it in the comparison, early.
Questions
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.
Yes — this one runs in your browser and your first check is free to preview, no account needed. It reads visible crown coverage from your top and back photos as a tier; an account is only for saving the baseline so a later check can compare against it.
The crown is the hardest angle because you can't aim a phone at the top of your own head — most people need a second mirror or another person. Guided top-and-back capture is built to put that whole area on record consistently, so you're not relying on one awkward overhead shot that looks different every time.
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.
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.
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.
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
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.
The report it produces
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.
