What Causes Male Pattern Baldness?
Androgenetic alopecia, commonly referred to as male pattern baldness, is the most common cause of hair loss in men. It is primarily driven by a genetic sensitivity to dihydrotestosterone (DHT), a potent derivative of testosterone.
When DHT binds to receptors in genetically susceptible hair follicles, it triggers a process known as miniaturisation. Over successive growth cycles:
- The growth phase (anagen) becomes shorter
- The resting phase (telogen) becomes longer
- The follicle shrinks in size, producing thinner and shorter hairs
- Eventually, the follicle ceases producing visible hair altogether
Clinically Proven Treatment Approaches
Hair loss is assessed by treatment approach, not by brand name. A clinician considering male pattern baldness will generally discuss two evidence-based routes with you:
- Prescription tablets: daily oral treatment available only after a doctor has reviewed your consultation and issued a prescription. It works by lowering the hormone signal that shrinks susceptible follicles. Because it is prescription-only, it is never advertised or sold directly on this site — suitability is decided by the prescriber, not the patient.
- Topical scalp treatments: non-prescription options applied directly to the scalp, which can support the growth phase of miniaturised follicles. Our clinical team can advise whether these are appropriate alongside, or instead of, prescription treatment.
When to Seek Medical Advice
Starting treatment early before hair follicles become permanently dormant yields the best clinical outcomes. If you notice a receding hairline or thinning on the crown, an online medical consultation with our clinical team can evaluate your suitability for prescription treatments.
