Track your hair. Understand your options.
Keep a consistent photo record, see what has actually changed, and make sense of the treatment options you’re researching.
Hair loss can take up more attention than you want to give it.
It is easy to start reading meaning into every shower, haircut, photo, or mirror. Day-to-day impressions are noisy: lighting changes, hair length changes, styling changes, and memory is a poor baseline. The goal is to give you a cleaner record, enough context to understand your options, and a way to check in without starting from zero every time.
