A receding hairline or thinning crown can send you down a rabbit hole of shampoos, supplements and impressive before-and-after photographs. Some treatments have evidence behind them, but the right starting point is understanding why you are losing hair.
Is it definitely male pattern hair loss?
Male pattern hair loss usually develops gradually, with thinning at the temples, crown or both. Genetics and sensitivity to a hormone called dihydrotestosterone (DHT) play a part.
Hair can also shed after illness, stress or significant weight loss, and some medical conditions and medicines can contribute. Sudden loss, bald patches, scalp pain or scarring should be assessed rather than treated on guesswork.
Which treatments have evidence behind them?
Finasteride and topical minoxidil are established options for male pattern hair loss. They work differently, neither suits everyone and results are not guaranteed.
Finasteride reduces DHT and can slow further hair loss, with some men also noticing regrowth. It is a prescription medicine, so suitability and risks need an individual assessment.
Topical minoxidil is applied to the scalp and can encourage growth. It requires consistent use, and scalp irritation or unwanted hair growth can occur. Follow the product instructions and seek advice if you develop symptoms such as palpitations, dizziness or swelling.
What should you know about finasteride’s risks?
Possible side effects include reduced sex drive, erection difficulties and ejaculation problems. Sexual side effects have sometimes been reported to continue after treatment stops. Depression and suicidal thoughts have also been reported.
Discuss any history of depression or suicidal thoughts with your prescriber. If you take finasteride 1 mg for hair loss and develop depression or suicidal thoughts, stop taking it and contact your doctor promptly. If you are at immediate risk of harming yourself, call 999.
How long should you give treatment?
Think in months rather than weeks. Changes can be gradual, and maintaining your existing hair may itself be a useful result. Photographs taken in similar lighting can make progress easier to judge.
Treatment generally needs to continue to maintain the benefit. If you stop, gains may gradually be lost. Discuss side effects or concerns with your clinician rather than continuing treatment at any cost.
What about shampoos and supplements?
A shampoo may improve how your hair looks or help a scalp condition, but that does not mean it treats male pattern hair loss. Supplements may help a confirmed deficiency; taking more vitamins than you need is not a reliable route to regrowth.
Hair transplantation is another option for selected people, but it does not prevent ongoing loss in untreated areas and needs careful planning.
Key takeaways
- Establish the cause before choosing treatment.
- Evidence-based options still carry risks and require realistic expectations.
- Assess progress over months, not daily mirror checks.
