Flares of seborrheic dermatitis common in winter
Seborrheic dermatitis (SD) is a close cousin of 'dandruff' and is due to a yeast known as Malassezia that is extremely common in the scalp.

Treatments for SD
I advise the vast majority of my patient to reach for shampoos containing zinc pyrithione (i.e. Head & Shoulders), selenium sulphide (Selsun Blue), ketoconazole (Nizoral), or ciclopirox (prescription Stieprox) at least once per week in the winter months. There are many myths surrounding these shampoos and they are undoubtedly one of the best kept secrets for great hair.
