Trichology, in your pocket
Point your camera at the problem.
One photo of the top of your head. HairGro maps your hair density, reads your hairline and scalp condition, and tells you what's actually driving the fall — then builds the routine around it.

How it works
Four steps, and the first one takes a minute.
Most people have already tried three oils and a shampoo before they get a straight answer. This is the straight answer first.
Scan
Hold your phone above your head. An on-screen guide tells you when the light, angle and distance are right.
Score
You get a hair health score out of 100, broken into density, hairline, scalp and breakage — with what each number means.
Plan
A daily routine built from your specific findings. Short, repeatable, and it tells you why each step is there.
Track
Rescan monthly. Your score, density and photos line up side by side so you can see whether it's working.
What we measure
Four readings, not one vague verdict.
"You're losing hair" is not information. These are the four things that change what you should actually do about it.
Hair density
Strands per square centimetre across the crown, mid-scalp and hairline, compared against your own last scan.
Hairline shape
Where your hairline sits now, how the temples are behaving, and whether the pattern is receding or holding.
Scalp condition
Visible flaking, redness, oiliness and buildup — the things that quietly undo everything else you're doing.
Breakage & texture
Split ends, mid-shaft breaks and thinning shafts — loss that looks like shedding but needs a different fix.
The scorecard
Plain findings. No fear-mongering.
Every issue we flag comes with two things: what it means in ordinary language, and whether it's typically reversible, manageable, or worth seeing a doctor about.
-
Severity, not slogansFindings are graded, so you know what needs attention this month and what doesn't.
-
Your baseline is youProgress is measured against your first scan, not a stranger's before-and-after photo.
-
We say when to see a dermatologistSudden patchy loss, scarring or scalp pain gets you a referral prompt, not a product recommendation.
Early crown thinning
Density at the crown is below your hairline and nape. Caught at this stage, the usual goal is to hold what you have and thicken existing strands.
Diffuse thinning at the crownFewer strands per cm² than the rest of your scalp, with no bald patch yet. Typically manageable.
Product buildup near the rootsVisible residue along the part line. Usually clears within a few weeks of a clarifying wash routine.
Every day after
The scan is the easy part.
What changes your hair is the six months after it. HairGro gives you a short daily routine and somewhere to ask the questions you'd otherwise type into a search bar at 1am.
Daily routine
Built from your findings, grouped by time of day, and never longer than it needs to be.

Your photos
A photo of your scalp is a personal thing.

Questions
Reasonable things to ask first.
Is this a medical diagnosis?
No. HairGro is a wellness and tracking tool, not a medical device, and it doesn't diagnose or treat any condition. If your scan shows something that needs a professional — sudden patchy loss, scalp pain, scarring, or loss alongside other symptoms — we'll tell you to see a dermatologist rather than sell you a routine.
How accurate is a phone photo?
Accurate enough to track change over time, which is what actually matters. A single photo can't replace a trichoscope in a clinic. What it does well is give you a consistent baseline and show you whether the same spot on your scalp is better or worse than it was six weeks ago.
What happens to my photo?
It's encrypted, stored against your account, and used to generate your scorecard and to compare against future scans. It isn't sold, shared with advertisers, or used to identify you elsewhere. You can delete any scan, or your whole account, from the app. Full detail is in the privacy policy.
Does it work for women?
Yes. Female pattern hair loss shows up differently — usually as widening at the part rather than a receding hairline — and the scorecard reads for both patterns.
Do you sell shampoo?
No. We aren't a product company, so the routine can recommend doing less, changing nothing, or seeing a doctor without costing us anything.
When am I charged?
Not during the 7-day trial. We send a reminder on day 5. If you don't cancel, the plan you picked starts on day 7 and renews until you cancel it. You cancel through your App Store or Google Play subscription settings.
