Oily Scalp Treatment: Why Your Scalp Is Greasy & How to Fix It
By: Peng Yu Yan
An oily scalp is caused by overactive sebaceous glands producing excess sebum. In Malaysia, heat and humidity naturally stimulate more oil production — which is why many Malaysians find their hair gets greasy within 24 hours of washing.
Excess oil on the scalp creates an ideal environment for Malassezia growth, which can progress to dandruff and seborrhoeic dermatitis. It can also clog hair follicles, potentially contributing to hair loss over time.
What makes it worse: over-washing (which strips oil and triggers rebound production), silicone-heavy conditioners applied to the scalp, touching hair frequently, and hormonal fluctuations.
TTE Headspa treatment: Our scalp balancing treatment uses a clay-based scalp mask to absorb excess sebum, followed by a sebum-regulating serum to normalise gland activity. Most clients extend time between washes from 1 day to 3 days within 4 sessions.
Frequently Asked Questions
How do I know if my scalp is oily or if I just have dirty hair?
Oily scalp feels greasy at the roots within 24 hours of washing, even without product buildup. If it takes 2–3 days to feel greasy, it may just be product residue.
Should I wash my hair every day if I have an oily scalp?
No. Daily washing signals your scalp to produce more oil (rebound effect). Wash every other day and use a dry shampoo in between to manage oiliness.
Can stress cause an oily scalp?
Yes. Stress raises cortisol levels which stimulate sebaceous glands to produce more sebum. Managing stress through exercise and sleep directly improves scalp oil balance.
Does diet affect oily scalp?
Yes. High glycaemic foods, dairy, and fried foods can increase sebum production. A diet lower in refined carbs and higher in zinc and omega-3 helps regulate oil production.
What ingredients in shampoo help with oily scalp?
Look for salicylic acid, zinc pyrithione, tea tree oil, or charcoal. Avoid silicones (dimethicone) and heavy conditioning agents which coat the scalp and trap oil.
