What Is Androgenetic Alopecia?

Androgenetic alopecia (AGA) is a genetically driven, androgen-mediated condition characterised by the progressive miniaturisation of scalp hair follicles. Under the influence of dihydrotestosterone (DHT) — a potent androgen derived from testosterone via the enzyme 5-alpha-reductase — susceptible follicles undergo successive cycles of reduced anagen duration and diminishing shaft diameter, until they produce only fine vellus hairs or cease productive cycling entirely.

In men, this typically follows the Norwood-Hamilton scale, beginning with a receding hairline and crown thinning (Norwood II–III), progressing through vertex loss (IV–V), and in advanced cases, confluent loss across the crown and temporal regions (VI–VII). In women, the pattern more commonly presents as diffuse central thinning over the crown while the frontal hairline is largely preserved — graded on the Ludwig scale (I–III). A minority of women present with a pattern closer to the male type, classified under the Sinclair scale.

According to research published on NCBI, androgenetic alopecia affects approximately 50% of men by age 50 and up to 40% of women during their lifetime, making it the most prevalent form of hair loss globally. For a broader overview of the hair growth cycle and how follicle miniaturisation fits within it, the About Hair Loss & Hair Growth page provides a useful foundation.

How Androgenetic Alopecia Progresses — and Why Early Treatment Matters

AGA is not a sudden event. It unfolds across years or decades through a process of follicular miniaturisation that is largely invisible in its early stages. Each hair growth cycle — anagen (growth), catagen (transition), telogen (rest) — is slightly shorter than the last. The shaft produced is slightly finer. The follicle's dermal papilla, which coordinates cellular signalling and nutrient uptake, gradually loses mass and function.

By the time visible thinning is apparent to others, many affected follicles have already been in decline for several years. Hair density visible on the scalp surface is a lagging indicator. At Norwood II–III or Ludwig I, a significant number of follicles are still viable — they are miniaturised but not yet lost. At Norwood V–VI or Ludwig III, the window for follicular rescue is considerably narrower.

This is why the timing of intervention matters more than most people realise. Treatments that stimulate microcirculation, deliver growth factors, and reduce follicular inflammation can meaningfully support follicles that are in progressive decline — but they cannot regenerate follicles that have been replaced by scar tissue. The earlier treatment begins, the more viable follicular tissue remains available to respond.

A gradual increase in scalp visibility, a change in ponytail diameter, or a finer texture at the crown are typically the earliest detectable signs. If you are reading this having already identified your stage, the practical implication is straightforward: the sooner a structured treatment protocol begins, the more impact it will have.

Why Singapore's Environment Accelerates Progression

AGA is genetically predisposed, but the rate at which it progresses is significantly shaped by the environment. Singapore's specific climate and lifestyle profile creates a set of compounding stressors that are rarely accounted for in international treatment guidance written for temperate climates.

[Climate] Chronic heat and sebum overproduction.

Singapore's average temperatures of 31–33°C year-round mean the scalp is in a near-constant state of elevated activity. High ambient heat drives increased sebum output, which — when oxidised or combined with sweat and particulate buildup — creates an inflammatory follicular microenvironment. DHT also concentrates in sebum; a consistently oily scalp is, in biochemical terms, a scalp with sustained local androgen exposure.

[Environment] Temperature cycling between humid outdoors and air-conditioned indoors.

Most Singaporeans cycle repeatedly each day between outdoor heat and aggressively air-conditioned interiors. This repeated thermal variation stresses the scalp's barrier function and impairs its ability to regulate moisture. The result is a scalp that is simultaneously prone to oiliness and to barrier compromise — a combination that increases follicular susceptibility to inflammation.

[Lifestyle] Cortisol load from high-pressure professional culture.

Sustained psychological and occupational stress chronically elevates cortisol. Cortisol suppresses dermal papilla signalling and can shorten the anagen phase, pushing follicles prematurely into telogen. For someone with androgenetic alopecia, this adds a telogen effluvium overlay to an already-present miniaturisation process — accelerating apparent loss beyond what AGA alone would produce at the same stage.

[Lifestyle] Nutritional deficits common in Singapore's urban diet.

Iron, zinc, vitamin D, and B-complex deficiencies are not uncommon in Singapore's working-age population, particularly in those with irregular meal patterns or high-exercise lifestyles. These micronutrients are directly involved in follicular proliferation and DNA repair during the anagen phase. Deficiencies do not cause AGA, but they reliably worsen its course.

The aggregate effect is that AGA in Singapore frequently progresses faster than the published Western literature would predict. Accounting for these environmental drivers is an essential part of any effective treatment strategy.

Treatment Options: A Direct Comparison

Androgenetic alopecia treatment broadly divides into three categories. Understanding the mechanism and trade-offs of each allows for informed decision-making — whether treatments are used alone or in combination.

These approaches are not mutually exclusive. A growing number of clients at Anagen Scalp combine regenerative protocols with medication prescribed elsewhere, or use regenerative treatment as a pre- and post-transplant support protocol. The question is not always "which approach?" but "which combination, and in what sequence?"

Treating Androgenetic Alopecia at Anagen Scalp

Anagen Scalp's protocols for AGA are built around four treatments, applied in combinations and sequences determined by stage, scalp condition, and treatment history. The goal in all cases is the same: restore the scalp environment, extend anagen duration, and deliver regenerative signals to follicles that remain viable.

Plasma Scalp Boost [Primary indication for early–moderate AGA]

Growth factor-rich plasma applied directly to the scalp dermis to stimulate angiogenesis, collagen synthesis, and follicular proliferation. At Norwood II–IV or Ludwig I–II, follicles are miniaturised but largely viable — making them well-positioned to respond to growth factor input. This is the primary regenerative treatment for AGA at Anagen Scalp. View Plasma Scalp Boost →

IndiScalp RF [Excellent for microcirculation and collagen remodelling across all AGA stages]

Controlled radiofrequency energy delivered to the scalp dermis generates thermal stimulation that improves microcirculation, activates fibroblasts, and promotes collagen remodelling in the perifollicular tissue. In AGA, the dermal papilla is progressively deprived of adequate blood supply — IndiScalp RF addresses this foundational deficit directly. It is effective as a standalone treatment and as a complement to Plasma Scalp Boost. View IndiScalp RF →

Scalp Pulse [Preparatory and adjunct; improves treatment uptake]

A mechanical scalp stimulation protocol that reduces scalp tension, improves lymphatic drainage, and enhances follicular access to circulating nutrients. In AGA, chronic scalp tension and reduced microvascular tone are common compounding factors. Scalp Pulse is typically used as a preparatory step before plasma or RF sessions, improving both comfort and treatment response. View Scalp Pulse →

TrichoJet Scalp [Maintenance and early-stage AGA]

Needle-free mesotherapy using high-pressure jet technology to deliver peptides, growth factors, and micronutrients transdermally. Well-suited to early-stage AGA (Norwood II or Ludwig I) where the goal is maintenance and slowing progression, or as an inter-session protocol between plasma treatments for moderate-stage clients.

What to Expect: Treatment Timeline by Stage

Response to treatment varies with AGA stage. The following reflects general trajectories across Anagen Scalp clients; individual results depend on scalp condition, follicular viability, and protocol adherence.

[Early stage] Norwood II–III / Ludwig I

At this stage, miniaturisation is underway but most follicles retain significant productive capacity. The primary goals are slowing further miniaturisation and supporting anagen extension.

• Weeks 1–4: Scalp environment assessment and preparation; Scalp Pulse and IndiScalp RF to optimise baseline circulation and barrier function

• Months 1–3: Plasma Scalp Boost series (typically 3–4 sessions at fortnightly intervals); may be combined with TrichoJet for active maintenance

• Months 3–6: Observable improvement in hair shaft calibre and reduced shedding volume; early-stage density changes may begin to emerge

• Months 6–12: Maintenance protocol (monthly or bi-monthly); consolidation of gains

[Moderate stage] Norwood IV–V / Ludwig II

Visible density loss is present. A significant proportion of follicles are in advanced miniaturisation. Treatment objectives shift toward stabilisation of remaining follicles and recovery of partially miniaturised ones.

• Months 1–3: IndiScalp RF prioritised to restore microcirculation in compromised zones; Plasma Scalp Boost series initiated

• Months 3–6: Continued plasma series; TrichoJet used for additional growth factor delivery between sessions

• Months 6–12: Stabilisation expected; density improvement typically more modest than in early-stage presentations but clinically meaningful

• Ongoing: Structured maintenance protocol essential to sustain results; AGA progression continues without active management

[Advanced stage] Norwood VI–VII / Ludwig III

At advanced stages, a significant proportion of follicles in affected zones have been replaced by fibrous tissue and are no longer capable of producing hair. Regenerative treatment can support remaining viable follicles and improve overall scalp health, but expectations regarding density recovery must be calibrated accordingly.

• IndiScalp RF and Scalp Pulse remain appropriate to maintain follicular environment in viable zones

• Plasma Scalp Boost targets areas where follicles are still detectable on scalp imaging

• A consultation at this stage will include an honest assessment of what is likely to respond and what is not

• For advanced loss, surgical consultation (hair transplant) may be the primary recommendation, with regenerative treatment used as pre- and post-operative support
