Hair loss treatments: what works, what to expect

Noticed thinning or more hair in the shower drain? You're not alone. Hair loss can be stressful, but there are clear, practical options that help most people. Below I cover the common treatments, how fast they work, what side effects to watch for, and when to see a specialist.

Medical treatments you can try at home

Topical minoxidil (Rogaine) is the go-to over-the-counter option. Apply it once or twice daily to the scalp. Many people start seeing slowed loss or thicker hairs after about 3–6 months. Side effects are usually scalp irritation; if that happens, try a lower strength or a foam formulation.

Finasteride (Propecia) is an oral prescription for men that blocks the hormone DHT, a common cause of male-pattern baldness. It often shows results in 3–6 months and more at one year. Known side effects include reduced libido or libido changes in a small number of users. Women of childbearing potential must avoid finasteride because it can cause birth defects.

Low-level laser therapy (LLLT) devices—helmets, combs, caps—aim to stimulate follicles. They need regular use (several times per week). Results vary, but some people see thicker hair after a few months. It's low-risk but can be pricey upfront.

Procedural options and lifestyle moves

Platelet-rich plasma (PRP) injections use your blood platelets to stimulate growth. Clinics usually recommend a series of sessions (often monthly for three), then maintenance every 3–6 months. Evidence is mixed but many patients report improvement. Expect mild scalp soreness after treatment.

Hair transplant surgery moves healthy follicles from one area to another. For permanent pattern hair loss, a transplant gives the most noticeable, long-term change. Full results take 6–12 months. It’s the most invasive and costly option, so choose a board-certified surgeon and review before/after photos.

Supplements and nutrition help only when you have a deficiency. Biotin, iron, vitamin D, and zinc can matter if tests show low levels. Taking random supplements without testing rarely helps and can create side effects.

Small daily habits make a difference. Avoid tight hairstyles, reduce harsh chemical treatments, manage stress, quit smoking, and eat a protein-rich diet with iron and vitamin D as needed. These steps won’t reverse genetic balding but help overall hair health and may improve response to medical treatments.

When should you see a doctor? If you lose hair rapidly, have patchy bald spots, scalp pain, or signs of infection, book an appointment. A dermatologist can diagnose the cause—genetic, hormonal, autoimmune, or medication-related—and recommend the best plan. Early action usually gives better results.

Final tip: pick one or two sensible treatments and stick with them for at least 4–6 months before judging. Hair cycles are slow; steady use and realistic expectations matter more than chasing quick fixes.
