Retain Measures Hair Loss Without Pretending to Cure It

Retain uses guided photos to score hair thickness over time, then compares that movement with the routine a user logs each day.

Landing page captured for the 2026-08-29 issue.

Field notes

The proposed workflow combines four fixed photo angles with a monthly comparison, rejecting images that do not meet its reading criteria. Users can log named routine steps, including finasteride, minoxidil, and microneedling, while the example dashboard separates crown, hairline, and temple movement. The sample report shows nine scans over six months and treats stability as a positive outcome rather than requiring visible regrowth.
