Male-pattern hair loss, also called androgenetic alopecia, usually develops gradually as a receding hairline, thinning crown or both. Treatment may slow further loss and help some regrowth, but response varies. Establishing the cause is the first step; not every episode of shedding is male-pattern baldness.

What causes male-pattern hair loss?
Inherited susceptibility and hormones, particularly dihydrotestosterone (DHT), contribute to progressive miniaturisation: affected hairs become finer. A family history can come from either side of the family. The British Association of Dermatologists’ patient leaflet explains this process and its variable progression.
How is the cause assessed?
A clinician reviews the pattern, timing and history of hair loss and examines the scalp. Sudden shedding, distinct bald patches or scalp inflammation should not simply be labelled male-pattern loss. Additional investigation depends on the findings. Start with a hair-loss assessment if the cause is uncertain.
Treatment options and their limits
Topical minoxidil
Minoxidil applied to the scalp can reduce loss and support growth in some men. Full regrowth is unlikely, and assessment of benefit may take six to twelve months. Scalp irritation can occur. Benefits are lost after stopping treatment. Follow product instructions and discuss suitability with a clinician.
Prescription finasteride
Finasteride can slow male-pattern hair loss and may support regrowth, but it is not suitable for everyone. Discuss medical history and potential sexual and mood-related side effects before treatment; some sexual side effects have been reported to persist after stopping. Ongoing treatment is generally needed to maintain benefit. These limitations are discussed in the American Academy of Dermatology’s treatment guide. Do not start or change prescription treatment based on this article.
Hair transplantation
A transplant moves donor follicles to thinning areas. It does not prevent further loss of surrounding hair. Suitability requires assessment of the donor area and a realistic long-term plan. Read about FUE and donor planning and how transplant results can change over time.
Other approaches
Evidence and response vary for approaches such as PRP and low-level light devices. Ask about the expected benefit, repeat-treatment burden, costs and alternatives. Cosmetic coverage is also an option; Monaris has discontinued hair-patch and non-surgical hair-replacement services.
Prepare for an assessment
- Note when thinning began and whether it has been gradual or sudden.
- Bring a list of medicines, supplements and previous hair treatments, including any side effects.
- Bring older photographs showing your hairline and crown.
- Explain your priorities: slowing loss, improving coverage, avoiding daily treatment, or understanding the diagnosis.
- Ask when to review progress and what would justify changing the plan.
Do I have to treat it?
No. Choosing not to treat confirmed male-pattern hair loss is a valid option. If it affects confidence or wellbeing, tell your clinician so this can be included in the discussion. Avoid judging treatment solely by promotional before-and-after images.
