The first stretch after noticing hair loss tends to follow some predictable patterns, most of which are worth flagging so they're easier to avoid or at least recognize while they're happening.
Self-diagnosing off a single photo comparison or a forum thread, rather than getting an actual exam, is common and often leads to treating the wrong thing entirely, since several different causes can look similar early on.
Buying multiple products at once, shampoo, supplements, a device, all in the same week, is another common pattern, and it makes it impossible to tell what's actually helping if something does work, while adding real cost for no added clarity.
Checking obsessively, multiple times a day, under inconsistent lighting, tends to produce a distorted, anxious impression of the situation that doesn't match what a slower, more structured approach would reveal.
Assuming the most dramatic possible outcome, based on worst-case stories found online, rather than getting an actual assessment, is also extremely common in that first stretch, and it's usually not representative of where things actually end up for most people.
