The four views
Keep enough forehead and surrounding hair visible to orient each image. Avoid extreme close-ups that make distance impossible to recreate.
Build a repeatable setup
Mark where you stand and where the phone is held.
Use the same fixtures and similar time of day.
Note dry or wet, styling products and part direction.
A haircut can change apparent coverage immediately.
Different lenses alter perspective and distance.
Allow enough time to look for a real pattern rather than noise.
Why random photos fail
A dark bathroom image, outdoor selfie and wet-hair photo do not form a reliable progression series. Differences in exposure and strand grouping can be larger than the visible change you are trying to detect.
How Baldly helps
Baldly keeps the capture sequence consistent and stores a chronological scan history. It can exclude low-confidence scans from trend interpretation rather than giving every image equal weight.
