Q. For the past three years I have had a residue appear on my scalp/hair when the cold weather hits. Nothing removes it. It is like my hair is constantly dirty even if I wash it twice a day. My beautician has never seen anything like it either. Once the spring arrives it mysteriously disappears. Any suggestions what it might be and if I should see a dermatologist?

A. A consultation with a dermatologist would be in order. It's a bit unusual that your skin condition has a seasonal component, which suggests you may be reacting to something in the environment.

Skin conditions with a hereditary aspect such as seborrheic dermatitis would commonly occur year round with some fluctuation due to temperature and humidity. A visit to your family doctor or a specialist would be helpful.
