Dry or itchy scalp, specifically behind the ears, is not uncommon in adults. This can be caused by any number of conditions, including inflammation or bacterial infection. There are several contagious skin conditions which can cause itching in the scalp as well.
Most Common Causes
If the itching is only accompanied by a few dry skin flakes, it is possibly a mild case of dandruff. Dandruff, an itchy rash tending to affect the entire scalp, is the most common cause of scalp disorders. Another common scalp disease is psoriasis, which often is found only on the back of the scalp. Dandruff and scalp psoriasis both exhibit red patches and may affect the ear area.
Less Common Causes
Folliculitis, caused when the hair openings become inflamed or infected, usually is marked by one or more pimples or scabs in the scalp or beard area. Bumps in the beard and neck area may be pseudofolliculitis barbae, or razor bumps. When on the back of the scalp, they may be acne keloidalis nuchae, or hair bumps.
Contagious Maladies
Head lice, most often seen in children, and scalp ringworm can also cause an itchy scalp and neck. Head lice are often detected by the appearance of eggs, or nits, attached to the hair shaft. Scalp ringworm is caused by several different types of fungi, and can manifest in several different ways. Variations depend on the type of fungus and how the individual's immune system reacts to the infection. The area of infection is sometimes marked by a bald patch containing broken-off hairs.
Treatments and Preventiion
Dandruff and psoriasis are most effectively treated naturally with coconut oil. Fungal infections respond well to rosemary, cedar wood or tea tree oil. The oils serve to improve scalp condition. The use of mild herbal shampoos will help restore the pH balance in hair and discourage bacterial growth. An herbal hair rinse containing henna should also be used regularly. Maintaining proper hygiene and keeping all hair supplies, towels and pillow-covers clean will reduce the chance of infection.
Clinical Treatment
In extreme cases, clinical treatment may be necessary. This treatment, usually taken daily or weekly, helps create a germicidal barrier on the scalp surface and stimulates the hair follicles. A steamer is used to open the head pores as medicated hair tonics, containing anti-dandruff agents, are applied. It is not advisable to attempt this measure of treatment outside a professional care clinic.
