How is hair loss treated, and when should I see a dermatologist?
Hair-loss treatment starts with identifying the cause. Pattern hair loss differs from shedding after illness or childbirth and from alopecia areata. Minoxidil, finasteride and supplements are not suitable for everyone; treatment follows assessment of the pattern and medical history.

Identify the pattern before buying treatment
Record when shedding began, whether it is diffuse or patchy, and any recent illness, medicine or dietary change. A clinician examines the scalp and may request tests when the history suggests a deficiency or medical cause. Everyone does not need the same laboratory panel.
Match treatment to the diagnosis
Minoxidil may help some cases of pattern hair loss. Other medicines may be appropriate after discussing their risks and benefits. Improvement takes time, and hair loss may return after effective treatment stops. Mention pregnancy or plans to conceive before using hair-loss medicines.
When to arrange assessment
Sudden shedding, bald patches, scalp pain or inflammation warrants evaluation. Avoid repeated traction and damaging styling. Do not take iron or high-dose vitamins solely because hair is falling out; supplements are appropriate when there is a demonstrated need, not as a universal remedy.
