Dandruff often worsens in winter due to dry air, changing routines, and stress. Experts suggest using medicated shampoos with ingredients like ketoconazole or zinc pyrithione to control fungal growth. Natural remedies like aloe vera and tea tree oil can soothe irritation. A balanced diet, hydration, and stress management also play key roles. For severe cases, consult a dermatologist for a personalized care.
