On the subject in the title: Hair shedding at month three: mechanism and time course Working notes rather than a conclusion.
Reporting something rather than asking about it, in case the pattern is useful to anyone else.
Over 24 weeks I logged this consistently: date, dose, time of day, and a simple severity score from 0 to 4 for each symptom. That is 170 data points, all self-reported, all unblinded, and collected by someone who knew what he expected to find. Treat it accordingly.
The reason I am posting is that my experience does not match the shape people usually describe here, and I would like to know whether that is unusual or whether the usual description is just the loudest version.
