Preparing for male hair loss starts with understanding its causes. The most common form is androgenetic alopecia (male pattern baldness), driven by genetic predisposition and the effect of dihydrotestosterone (DHT) on hair follicles. A DNA test (e.g., for AR or SRD5A2 variants) can offer clues but is not diagnostic. A medical evaluation by a dermatologist is essential to rule out other causes like iron deficiency, thyroid disorders, or stress. Lifestyle measures such as a balanced diet (iron, zinc, vitamin D), stress management, and gentle hair care may support hair health but cannot replace proven treatments. Approved medications like minoxidil and finasteride have solid evidence, though side effects exist. Supplements (biotin, silica) lack strong support. The evidence for 'preparation' is mostly mechanistic and practice-based, not from large trials. Key takeaway: early intervention improves outcomes, but overhyped genetic tests or supplements should be viewed with caution.
