Dandruff's central actor is Malassezia - a normal scalp yeast whose digestion of scalp oils irritates susceptible skin into flaking. The accomplices: oiliness, winter, stress, infrequent washing and heavy products. And the myths cleared: not dirt, not contagious, not caused by shampoo.
Dandruff has one central cause and several accomplices. Understanding them explains why flakes come back every winter and why stress weeks show up on your shoulders.
Dandruff is your scalp's inflammatory reaction to a normal oil-eating yeast - amplified by oiliness, winter, stress and infrequent washing, and never caused by dirt or catching it from someone else.

The honest home-remedy ranking: regular washing, aloe vera, curd masks, diluted neem and formulated tea-tree products have logic or evidence behind them; undiluted vinegar, baking soda and neat essential oils belong in the skip pile. Where remedies genuinely fit in a dandruff plan.
The classics named dandruff Darunaka and filed it among the minor diseases - Kapha-Vata in the scalp, treated with neem and herbal oil care. That tradition makes a genuinely pleasant comfort layer over the antifungal shampoo doing the real work - with oiling kept short and strictly pre-wash.
No food causes or cures dandruff - but zinc, B vitamins, omega-3 fats, protein and a low-sugar whole-food plate give the scalp its best supporting conditions. What the evidence supports, what is mythology, and a practical plate for the flaky months.
Treating dandruff is a four-week project with a lifetime tail: the right antifungal shampoo used correctly, rotated if it stalls, a dermatologist for the inflamed or stubborn, and one weekly maintenance wash forever after. The complete playbook.
Dandruff cannot be fully prevented, but control is a routine: wash regularly, keep one weekly medicated maintenance wash, rinse clean, wash after sweaty workouts, oil only short and pre-wash, and manage stress. The habits that keep a universal yeast invisible.
Dandruff runs three practical grades: occasional flakes handled by routine care, persistent flaking needing a properly-used medicated shampoo, and inflamed spreading disease that belongs to a dermatologist. Plus the relapse rhythm - and why lifelong gentle maintenance is the honest endpoint.
