Your scan history
Every scan you have ever taken is kept, under Scans. Nothing ages out and nothing is thinned to save space.
Finding a scan
The archive is a timeline, newest first. You can jump to a month, or search by week, area or follicle state when you remember something about a scan but not when it was.
Your first scan is marked as your baseline - every later scan is measured against this one - because it is the one you will come back to most.
What one scan record holds
Opening a scan gives you, for that week:
- How many areas were read, out of the areas you photographed that week. A capture that came out unclear is counted honestly, so you may see 4 of 5 zones read; an area you did not photograph shows as not taken
- The photographs, area by area, with the date they were taken
- What the scan shows, and what may have changed
- What the coach saw - a line per scan, written by the same reader that looks at everyone’s
- A marker where you have already asked the coach about this scan
How often you can scan
A new scan unlocks seven days after your last one. The countdown is shown, and the archive also tells you how you have actually been going: how often you scan, your usual gap, and your longest pause.
The wait is deliberate rather than a limit on your account. Hair does not change measurably in two days, so two scans in one week produce a difference made almost entirely of lighting and camera angle - exactly the noise the weekly rhythm exists to avoid.
When something is missing
| What you see | What it means |
|---|---|
| That scan is not here | The link is old, or the scan belongs to another account. Your own scans are all in the archive |
| We could not load your scans | A problem reaching the archive, not a change to it. Nothing has been lost - try again |
The second one matters. A failure to load is never a sign that your history has gone. Densy deliberately separates “we could not fetch this” from “there is nothing here”, so that a bad connection cannot look like an empty archive.
