Scalp Biology
Understanding why your scalp behaves the way it does — through follicle anatomy, microbiome science, sebum regulation, and the specific environmental pressures of the Malaysian climate.
4.5–5.5
Optimal scalp pH
Scalp pH & the Acid Mantle
The scalp's acid mantle operates between pH 4.5–5.5. Malaysian tap water (pH 7–8.5) and most shampoos apply a daily alkaline challenge that disrupts antimicrobial defense and sebum enzyme activity.

Higher Malassezia risk in KL
Malassezia & KL Humidity
KL's 80% average humidity creates conditions where Malassezia overgrowth is 3× more likely than in temperate cities. The yeast produces oleic acid — an inflammatory fatty acid that penetrates the stratum corneum.
5α
Reductase enzyme target
DHT & Follicle Miniaturisation
Dihydrotestosterone binds to androgen receptors in follicle dermal papilla cells, progressively shortening the anagen phase and shrinking follicle diameter. 5α-reductase is the enzyme target for intervention.

Microbial species on scalp
Scalp Microbiome Balance
A healthy scalp is Cutibacterium acnes-dominant. Humidity, heat, and product buildup shift the balance toward Malassezia. The intervention point is the follicular microenvironment, not the hair shaft.
Quick Reference
Follicle Anatomy & Hair Cycle
Anagen
2–7 years · 85–90% of scalp hairs
Active growth phase. Follicle dermal papilla divides rapidly, producing hair shaft. GH, IGF-1, and Wnt signalling drive this phase.
Catagen
2–3 weeks · 1–2% of scalp hairs
Regression phase. Follicle detaches from dermal papilla. Hair growth stops. Triggered by cortisol, DHT, and inflammatory cytokines.
Telogen
3–4 months · 10–15% of scalp hairs
Resting phase. Hair remains anchored but no growth occurs. Ends when new anagen hair pushes the telogen hair out. Stress extends this phase.
