Hair changes before you can see it.
Densy reads the same five scalp zones on a schedule, so a change shows up as a number instead of a feeling.
Five zones, read separately
Four bands
What a reading tells you
Every follicle in a zone falls into one of four states. A reading is the mix, and progress is the mix shifting right.
Waking up
Pores opening — nothing to see in the mirror yet
Sebum plugs clearing and pores reopening. Both mean the stimulation is working, and neither is visible.
27% of this sample reading
A sample reading — not a real member
Three steps
How it works
A first reading to measure against, then the same five zones on a schedule.

Baseline
A guided capture of five zones. This is the reading everything later is compared against.

A sample reading — not a real member
Zone reading
Each zone is graded into the four states, and the mix is recorded.

Routine
A routine cued to the zones that need it, adjusted as later readings come in.
Month 0 to 6
What it watches over time
What follows is what Densy looks for, not what it promises you will get.
- Month 0
Smooth scalp, pores closed
- Month 1
Pores start to open
- Month 3
Fine, pale down appears
- Month 6
Down thickens into hair
Hair changes slowly and unevenly, and a single reading is a snapshot. The value is in the comparison, not in any one number.
Rollout
Who it starts with
Densy is being rolled out one group at a time, so the readings are compared against people whose situation resembles yours.
Crown thinning
Watching the vertex open up.
Stress-related shedding
A recent change with a cause you can name.
Post-menopause thinning
Diffuse loss following a hormonal shift.
More groups are being added. If none of these describes you, the questionnaire will still tell you whether Densy can read your scalp today.
Pricing
What it costs
Two ways in. Neither is the recommended one.
Your photographs
Your photographs, and what Densy cannot tell you
Scalp photographs and the answers you give in the questionnaire. The photographs are what the reading is produced from.
- Densy measures what a scalp photograph can show. It is not a diagnosis and it does not replace a dermatologist.
- Some causes of hair loss are outside what Densy can assess, and a reading cannot rule them out.
- If something in your reading needs a clinician, the right next step is a clinician.
