2. Medical treatments: the backbone of management

For most men, the backbone of treatment rests on two pillars:

• agents that prolong anagen and support follicle function, and
• agents that reduce or blunt androgenic signalling at the follicle.

2.1 Minoxidil (topical and oral)

How it works

Minoxidil is a potassium channel opener with vasodilatory properties. At the follicle level, it:

• prolongs the anagen (growth) phase
• promotes earlier re-entry into anagen after telogen
• increases local blood flow and growth factor expression

The net effect is that more hairs are in active growth at any given time, the shafts become thicker from previously miniaturised follicles, and hair shedding is reduced over time.

Topical minoxidil

• Available as 5% solution or foam, often applied once or twice daily.
• Widely used, with decades of data in men.
• Best suited to men willing to build it into a daily routine and tolerate a slightly “styled” feel to the scalp.

Common early experiences include a transient increase in shedding during the first few weeks as older telogen hairs are shed, and mild irritation or scaling in some men, which is often manageable by adjusting the formulation or application technique.

Low-dose oral minoxidil

Oral minoxidil, at low doses, has become an option for men who:

• cannot tolerate topical vehicles
• dislike the texture on the scalp
• do not achieve sufficient benefit from topical use alone

Typical doses in hair practice are far lower than those used historically for blood pressure. Side-effects to counsel include:

• ankle oedema (swelling)
• increased body or facial hair
• occasional postural lightheadedness or palpitations in susceptible individuals

It is not suitable for everyone and requires medical oversight, but can be very effective in appropriately selected men.

2.2 Finasteride

Mechanism

Finasteride is a selective inhibitor of type II 5α-reductase. It:

• reduces the conversion of testosterone to dihydrotestosterone (DHT)
• lowers DHT levels in scalp and serum
• decreases androgenic signalling in susceptible follicles

By reducing DHT, finasteride helps slow or stop further miniaturisation, allows some miniaturised follicles to regain thicker output, and stabilises overall pattern loss.

Use in practice

• Commonly used at 1 mg once daily for male pattern hair loss.
• Often combined with topical or oral minoxidil.
• Can maintain hair and sometimes improve density for many years in men who respond and remain adherent.

Side-effects and considerations

Potential adverse effects include reduced libido, erectile dysfunction, and mood changes or gynaecomastia (growth of breast tissue) in a small minority of users.

The absolute risk is low but not negligible. Some men experience no side effects at all; others decide the trade-off is not acceptable. Finasteride is contraindicated in women who are or may become pregnant, and tablets should not be handled by pregnant partners.

A thorough, honest discussion about benefits, risks and uncertainties is essential. Many men find that trying finasteride with close self-monitoring allows them to make an informed decision based on their own experience rather than relying on online extremes.

2.3 Dutasteride

Dutasteride inhibits both type I and type II 5α-reductase, leading to a more profound suppression of DHT than finasteride.

• Used off-label for androgenetic alopecia in men, typically at 0.5 mg daily or less frequent dosing, such as thrice weekly.
• Studies suggest it can be more potent than finasteride, particularly in men with more advanced loss.
• Side effect profile is similar in nature to finasteride, with a slightly different pharmacokinetic profile (a longer half-life and a longer duration of action).

In practice, dutasteride is often reserved for:

• men who do not respond adequately to finasteride
• men with more aggressive early-onset loss
• men comfortable with off-label use and longer half-life considerations

Again, informed consent and monitoring are vital.

2.4 Topical finasteride and combination formulations

Topical finasteride has emerged as a means to target scalp DHT with lower systemic absorption.

• It can be used alone or in a single combined preparation with minoxidil.
• Early studies show promising reductions in scalp DHT and improvements in hair counts, with much smaller changes in serum DHT compared with oral dosing.

This may be an attractive option for men who are reluctant to take oral finasteride but are open to topical androgen-modifying therapy, or those who have had mild systemic side effects with oral dosing.

The data are still evolving, and long-term outcomes and safety require ongoing study, but topical finasteride is likely to play an increasing role, particularly in combination sprays.

2.5 Other medical adjuncts

Several other medical tools can support the core treatments:

• Ketoconazole shampoo: has anti-inflammatory and mild anti-androgenic properties on the scalp; often used a few times per week to improve seborrhoeic dermatitis and potentially complement other treatments - evidence is limited.
• Caffeine or botanical shampoos: marketed for hair loss, but robust evidence for a significant impact on male pattern hair loss is limited; they can form part of a gentle hair care routine, but should not be relied upon as primary therapy. Other similar lifestyle interventions are discussed in the 'Prevention and Hair Health' section.
• Anti-androgens such as spironolactone are generally not used in men for hair loss because of feminising side-effects and effects on blood pressure and potassium.

3. Procedural and regenerative treatments

These treatments aim to enhance follicular function or improve the scalp environment. They are usually used alongside, not instead of, medical therapy.

3.1 Platelet-rich plasma (PRP)

PRP involves:

• drawing a small volume of the patient’s blood
• concentrating the platelets via centrifugation
• injecting the platelet-rich fraction into areas of thinning scalp

Platelets release growth factors that may promote anagen entry and prolongation, improve follicular vascular support, and modulate local inflammation.

Clinical studies in men have shown modest to moderate improvements in hair density and shaft thickness in some patients. Best results when used in a series of sessions and combined with minoxidil and/or finasteride.

Protocols vary widely between clinics, and techniques are not standardised. PRP is generally safe when performed correctly, but cost and variability in response should be discussed, as it can be quite expensive for the modest improvement it yields.

3.2 Microneedling

Microneedling, also known as derma-rolling, uses fine needles to create controlled micro-injury in the scalp.

It appears to stimulate wound-healing pathways, including growth factors that support follicles, and enhance the penetration of topical agents such as minoxidil. That is the working theory, and evidence suggests some benefit.

Randomised trials have shown that men using microneedling plus minoxidil can achieve greater improvements than minoxidil alone in some settings, but these studies are mostly small and short-term.

There is a growing community advising against microneedling due to direct damage to hair follicles and formation of unwarranted scar tissue, which is plausible. While causing micro-injuries will stimulate the release of growth factors, if performed incorrectly (i.e. too frequently, or with excessive depth or pressure), it can lead to temporary or permanent scarring alopecia.

It is also quite a hassle to perform consistently, and very uncomfortable. It's also difficult to perform with long hair.

Microneedling can be performed in a clinic or with properly designed home devices under guidance. Depth, frequency and hygiene all matter; aggressive, unsupervised use is not advisable.

3.3 Low-level laser therapy (LLLT)

LLLT devices use specific wavelengths of red or near-infrared light to stimulate follicles. Proposed mechanisms include:

• increased mitochondrial activity
• modulation of reactive oxygen species
• promotion of anagen

Clinical studies report improvements in hair counts and thickness in some men with androgenetic alopecia, with the best outcomes from regular use several times per week over months.

LLLT is non-invasive and generally safe, but requires conscientious adherence. It is best positioned as a supportive therapy rather than a standalone solution.

3.4 Emerging regenerative therapies

Stem-cell-derived products, including exosomes, are under active research:

• The idea is to deliver signalling molecules that can awaken dormant follicles or improve the micro-environment.
• Early small studies are promising but far from definitive.
• Regulatory frameworks and long-term safety data are still in development.

At present, these should be considered experimental. Men should be wary of strong claims around “stem cell cures” that are not backed by robust, peer-reviewed evidence.

4. Surgical hair restoration

Essentially, the cure for balding.

Surgery does not slow or treat the underlying androgenetic process. Instead, it redistributes more resistant follicles from the back and sides (the donor area) to areas that have thinned.

Hair transplantation is discussed in greater detail in our separate articles within the Treatment section of the Knowledge Hub.

4.1 Who is a candidate?

Surgery is best suited to men who:

• have a confirmed diagnosis of androgenetic alopecia,
• have enough stable donor hair,
• understand the progressive nature of their loss,
• are realistic about what surgery can achieve,
• are ideally on some form of medical stabilisation (finasteride, dutasteride, minoxidil) to protect non-transplanted hair.

Very young men with rapidly evolving patterns, or men with unstable hair loss, are usually advised to postpone surgery and focus on medical stabilisation.

4.2 Techniques: FUT and FUE

Two main harvesting methods exist:

Follicular Unit Transplantation (FUT or “strip surgery”)

• A strip of scalp is removed from the donor area.
• The wound is closed, leaving a linear scar.
• The strip is dissected into individual follicular units under a microscope.
• These are implanted into recipient sites.

Advantages:

• efficient harvest of large numbers of grafts, with greater preservation of overall donor area
• potential for excellent graft quality
• often ideal for men with longer hairstyles, and when high graft numbers are needed

Follicular Unit Excision (FUE)

• Individual follicular units are removed directly from the donor area using small punches.
• Leaves tiny dot-like scars scattered throughout the donor zone.

Advantages:

• no linear scar
• often preferred by men who keep their hair very short
• able to perform massive sessions with a high number of grafts

Both methods can yield natural results in experienced hands. The choice depends on:

• donor characteristics
• hairstyle preferences
• required graft numbers
• surgeon expertise and philosophy

4.3 Planning and execution

Key planning principles include:

• designing an age-appropriate, natural hairline
• prioritising frontal framing over dense crown coverage when donor hair is limited
• respecting safe donor limits to avoid visible depletion
• anticipating future loss and leaving a reserve for potential second procedures

Post-operative care focuses on graft survival, minimising shock loss, and integrating medical therapy to protect existing hair.

5. Lifestyle and special situations in men

5.1 Anabolic steroids and testosterone use

Men using anabolic androgenic steroids or high-dose testosterone:

• often see an acceleration of androgenetic alopecia if genetically predisposed
• may require particularly careful discussion of expectations; medical therapy can blunt but not fully counteract supraphysiological androgen exposure

Stopping or reducing androgen doses is sometimes the most impactful “treatment”, though this is a complex decision in the context of performance enhancement or gender-affirming therapy.

5.2 Smoking, crash dieting and general health

Smoking, crash dieting and uncontrolled systemic disease all make life harder for follicles. Addressing these does not replace finasteride or minoxidil, but it removes additional insults and supports better outcomes from whatever treatment is chosen.

6. Building a long-term plan

Male pattern hair loss lasts a lifetime. Effective management requires a long-term mindset.

Helpful ways to frame it:

• Think in quarters, not weeks:
  • Quarter one: stabilise and start treatment
  • Quarter two: begin to see reduced shedding and early thickening
  • Quarters three and four: consolidate improvements
• Review periodically: adjust therapy, reassess pattern, and revisit expectations as circumstances change.
• Accept that some level of maintenance is required. Stopping effective treatment almost always leads to a return to your untreated trajectory.

The ideal plan for any individual will depend on:

• age and pattern
• tolerance for different treatments
• past medical history
• preferences around surgery and appearance
• appetite for risk versus benefit,

There is no single “best” treatment. However, there is usually a best-fitting combination for a man's biology, priorities and stage of life.
