Seborrheic Dermatitis(Scalp Condition)-Hairline Loss Due To Sickness

According to the Mayo Clinic, seborrheic dermatitis, also called seborrheic alopecia, is a harmless inflammatory skin condition marked by small, discolored patches or spots on the skin and scalp that can result in hair loss in large affected patches.

Less severe is regular dandruff, small skin flakes on the scalp and within the hair, and atopic dermatitis, a mild skin or scalp reaction from unknown causes. The hair loss from these conditions can be reversed once the conditions are controlled. But don’t scratch and risk a secondary infection, which may scar, advises Callender.
