Flaky Scalp in Humid Weather: Causes and Care

Quick answer: A flaky scalp in humid weather is often linked to oil, sweat and yeast, as with dandruff or seborrhoeic dermatitis. Regular gentle washing and avoiding heavy products usually help; see a doctor if flaking is thick, red, itchy or spreading.
- Sweat and oil: Wash after sweating.
- Products: Rinse well and avoid build-up.
- Doctor: For persistent or severe flaking. See hair doctor Malaysia.
