Itchy Scalp And its Causes!

Irritation on your scalp can be an embarrassing and frustrating problem, especially when you get the continuous urge to scratch your head. There can be lots of causes for an itchy scalp and it is important to identify the cause and treat it accordingly. Some of them include:

Seborrheic dermatitis or dandruff

The symptoms of this condition include redness, irritation and skin flakes. Seborrheic dermatitis can occur in any part of the body due to excessive growth of a fungus called malassezia and when it hits the scalp it is called dandruff. It can be a recurring problem for some, but it is treatable with prescribed shampoos and steroid creams. Cosmetic shampoos targeted to cure dandruff works too.

Head lice

Not only children, but adults can get lice too. It is mistakenly thought that poor scalp health causes lice but actually they breed in clean hair. Small white flakes that look like dandruff are actually lice eggs that cannot be shed off easily; they need to be treated with medicated shampoos containing insecticides pyrethrin or permethrin.

Psoriasis

Psoriasis is an autoimmune skin disorder that can occur in any part of the body including the scalp. The symptoms are same as dandruff with raised red patches of skin. People with psoriasis are more likely to incur dandruff and itchy scalp. The exact cause of the disorder is not known, though heredity is a popular belief.

Eczema and allergic reactions

Redness, flakes, irritation are the signs of eczema and allergic reactions. During summers with excessive perspiration the condition worsens. It usually occurs in children but adults can get eczema too. Over the counter medications helps in reducing the severity of the symptoms and gradually heal the condition. If you wish to discuss about any specific problem, you can consult a Dermatologist.
