Hair loss: what’s really happening and what you can do

Hair loss can feel sudden and personal, but most types have clear causes and clear steps you can take. Some shedding is normal. If you notice widening part lines, a receding hairline, or clumps in the shower, act early — chances of improvement are much higher than you think.

Simple tests and when to see a doctor

Start with a short checklist: Did hair loss begin after childbirth, a fever, a new medication, major weight loss, or intense stress? That points to telogen effluvium, which often recovers in months. Patchy loss or scalp pain needs immediate medical review — infections and autoimmune causes like alopecia areata behave differently.

Ask your doctor for a few basic tests: thyroid-stimulating hormone (TSH), a complete blood count, iron studies (ferritin), and vitamin D. Low iron or thyroid problems are correctable causes. If diagnosis is unclear, a dermatologist may do a scalp exam, pull test or biopsy to tell scarring versus non-scarring loss.

Practical treatment options and everyday tips

Minoxidil (topical) is the easiest first step. Use it as directed every day and give it at least 3 to 6 months. You may see shedding first — that’s hairs cycling — but many people get thicker hair with continued use. Side effects are usually mild scalp irritation.

Finasteride (oral) works well for many men by blocking DHT, a hormone linked to male-pattern loss. Expect 3–6 months before results. Discuss possible sexual side effects with your doctor. Women of childbearing age should not take it.

For women, options include topical minoxidil, oral spironolactone, or hormonal approaches if excess androgens are present. Birth-control adjustments help some people, but only after a clinician checks hormones.

Medical procedures that help: platelet-rich plasma (PRP) injections show promise for many people, and low-level laser therapy can support regrowth when used regularly. Hair transplants move existing hair and give permanent results for suitable candidates; they require realistic expectations and a skilled surgeon.

Diet and daily habits matter. Avoid tight hairstyles, reduce hot-tool styling, use a gentle shampoo, and treat wet hair carefully — it’s when strands are weakest. If blood tests show low iron or vitamin D, treat deficiencies first; supplements won’t help otherwise.

Quick timeline: telogen effluvium often improves in 3–6 months; medication-based gains appear after 3–6 months and keep improving up to a year; transplants show visible growth after several months and mature by 12–18 months.

When to act fast: sudden patchy loss, pus or severe pain on the scalp, or rapid shedding after stopping birth control or a new drug. Otherwise, start with tests, pick one proven treatment, and be consistent. Small daily steps add up.
