I'm having trouble with dry skin. particularly on my scalp, and under my beard. its large white flakes, normally dry, but sometimes waxy. no itchiness unless aggravated or unclean. it infrequently clears up. became worse when moved to ct from durban.

Well : Can be seborrheic dermatitis Or dry skin problem. See dermatologist in person for diagnosis and treatment

Not uncommon: This is quite common.Head & Shoulders may help — its active ingredient pyrithione zinc fights off fungi and bacteria, and treats mild seborrhoeic dermatitis (another possible cause of dandruff)..Ketoconazole,selsum blue,Nizol alao helps.The skin under beards tends to dry out and can use different products and they also make beard oil for such problems.
