Full Answer

Seborrheic dermatitis is a common skin condition known as dandruff when it affects the scalp, notes WebMD. While over-the-counter shampoos can be used to treat dandruff, some individuals may need a doctor's prescription for steroid cream or a more powerful shampoo.

An individual whose immune system is creating too many skin cells may experience psoriasis, which can lead to itching and flaking of the scalp, says WebMD. It's important to note that an individual who has psoriasis has a greater chance of having dandruff, but not everyone who has dandruff automatically has psoriasis.

While eczema is more prevalent in children and infants, anyone can get it, according to WebMD. The mysterious skin condition can be treated with special steroid creams and moisturizers. A person with eczema should not scratch his scalp or use harsh soaps.

A person can avoid having a dry scalp by washing his hair either every day or every other day, notes WebMD. Experiencing an itchy scalp is also more common in the winter season.
