Hair Loss in Men
Causes, symptoms, and evidence-based treatments for male hair loss — plus practical steps to protect density and plan your next move.
Around two-thirds of men experience some degree of hair loss by 40, with prevalence rising further by 50. While there’s no permanent “cure” for chronic types such as male pattern baldness (MPB), effective strategies can slow shedding, maintain coverage, and in some cases stimulate visible thickening.
Before choosing a treatment, it helps to understand the main categories, common causes, and typical signs.
The Three Primary Types of Hair Loss in Men
- Anagen effluvium – Rapid loss from treatments that affect follicles in the growth phase (e.g., chemotherapy). May be temporary or longer-term depending on the cause.
- Telogen effluvium – A higher-than-normal number of hairs shift into the resting (shedding) phase, often after stress, illness, medication change, or deficiency. Usually temporary once triggers are addressed.
- Androgenetic alopecia (MPB) – Genetic sensitivity to androgens causes gradual miniaturisation, typically with receding temples/hairline and crown thinning. This is the most common type in men.
To understand progression, see the Norwood–Hamilton Scale.
Common Causes & Triggers
- Male pattern baldness (MPB): Driven by genetic factors and androgen sensitivity (not higher testosterone). Presents as hairline recession and/or crown thinning.
- Seasonal shedding: Temporary increases in fall/winter for some men; can accentuate underlying MPB.
- Alopecia areata: Autoimmune, patch-type loss that can expand; often temporary but unpredictable.
- Traction & styling stress: Tight styles, frequent high-heat tools, harsh chemical services.
- Medical & nutritional factors: Thyroid imbalance, ferritin/iron or vitamin D deficiency, rapid weight change, medications, significant illness or surgery.
Typical Symptoms & Patterns
- Receding hairline at the temples (M-shape), thinning at the vertex/crown
- Diffuse thinning across the top in some cases
- Increased scalp visibility and reduced hair calibre (finer strands)
- Periods of heavier shedding after stress/illness or seasonally
How to Treat Hair Loss in Men
Expect 3–6 months of consistent use before judging results. Combining modalities often works best.
- Topical minoxidil (5%) – OTC; can increase hair counts and calibre. Initial shedding is possible; irritation can occur in some users.
- Oral finasteride – Prescription; reduces scalp DHT to slow progression and maintain density. Discuss benefits/risks and side effects with your clinician.
- Ketoconazole shampoos – Support scalp environment; often used 2–3× weekly alongside other treatments.
- Microneedling – Enhances topical absorption and may stimulate growth factors; consider weekly/biweekly protocols with guidance.
- Low-Level Laser Therapy (LLLT) – Caps/hoods/combs may complement a regimen; results vary but can assist adherence and scalp health.
- PRP therapy – In-clinic platelet-rich plasma injections; typically used in combination plans.
- Correct deficiencies & optimise lifestyle – Address ferritin/iron, vitamin D, thyroid; prioritise protein intake, sleep, and stress management.
- Surgery (hair transplant) – For suitable candidates with stable loss and adequate donor hair; results depend on surgeon skill and patient factors.
Drug-Free Support: HR23+
HR23+ is a premium, drug-free supplement designed to help reduce excessive shedding and support stronger, fuller-looking hair. It pairs well with topical routines, microneedling, ketoconazole shampoos, and LLLT — especially in the early to mid stages of thinning.
- Supports follicle health and growth cycles
- Complements minoxidil-based or non-drug routines
- Suitable for ongoing maintenance to preserve density
When to See a Specialist
If thinning is rapid, patchy, or accompanied by scalp symptoms — or you’re unsure of the cause — book a review with a GP, dermatologist, or trichologist. Early clarity prevents missteps and protects long-term coverage.
