Puberty & Sebum Production: Why Hair Gets Oilier

Yes. Puberty triggers a surge in androgens (testosterone, DHEAS) → stimulates sebaceous glands → increased sebum production → oilier scalp, face, and acne onset.

Physiology

• Sebaceous glands are androgen-sensitive (via nuclear androgen receptors).
• Adrenarche (6–8 yrs): DHEAS rise → early sebum increase.
• Gonadarche (10–14 yrs): Testosterone surge → marked sebum escalation.
• Peak sebum: late teens/early 20s; declines gradually after 40.

Management

• Frequent washing with mild surfactant shampoo (daily if needed).
• Avoid harsh scrubbing (stimulates more sebum).
• Scalp-targeted treatments: zinc pyrithione, salicylic acid, niacinamide.
• Topical retinoids / anti-androgens (spironolactone) for severe acne/seborrhea — dermatologist.

Reassurance: this is normal physiology, not poor hygiene.
