Dandruff is a shedding of the skin on the scalp that leaves white
flakes on the head, neck, and shoulders. It may be a form of a skin condition
called
eczema, which causes increased shedding of normal
scalp skin cells. Hormonal or seasonal changes can make dandruff worse.
Home treatment is usually all that is needed to solve common scalp
problems. Flakes of dead skin on the scalp caused by dandruff may be treated
with anti-dandruff shampoos and should go away in about 2 weeks.
Sometimes what looks like dandruff may actually be another problem,
such as
ringworm of the scalp, which is treated with
prescription antifungal medicines.
Seborrhea and eczema may occasionally be mistaken for
dandruff.
If you still have symptoms after 2 weeks of home treatment for
dandruff, or if symptoms involve more than flakes of dead skin, see your doctor
for evaluation and treatment.
