The Truth about Dandruff

When you see white or yellow particles in your hair, you might have dandruff. Flakes of dandruff are actually dead skin cells. If you have dandruff, the scalp can be scaly, red and itching. Scratching will increase the detachment of dead skin on the head. You can better see dandruff when wearing dark clothing.

Causes

In this case, there is no known cause. If you have dandruff, it does not mean you have dirty hair.

Experts say it is caused most likely by a fungus. Hair follicles and glands in the skin produce natural oil called sebum, which can facilitate the development of fungi. Some of these fungi are found usually in the skin, but when they multiply excessively, they can cause dandruff. Also, too much sebum can cause dandruff.

In addition, prolonged exposure to dry air can cause skin dryness, which could favor the presence of dandruff.

The way you treat your hair and, especially, the substances you use can damage the scalp. Some hair dyes can cause skin reactions, which may resemble dandruff. If you already have dandruff and wash your hair less often, visible symptoms of the condition may increase because dead skin cells can accumulate in the hair.

Dandruff may increase during the months when the air is dry. Cold and dry weather common in winter can worsen dandruff. Other triggers include stress and fatigue.

Sometimes dandruff can occur in several areas of the body other than the scalp, such as the forehead, eyebrows, eyelashes or ears. Flaky skin on areas of the body, covered with hair may be a sign of dandruff – which is a mild form of seborrheic dermatitis. If your skin is oily or shows a slight redness, contact a dermatologist because you suffer from seborrheic dermatitis.

Other conditions that can damage the scalp

Other skin problems that can damage the scalp include acne, eczema or psoriasis. People with serious medical problems such as epilepsy, Parkinson’s disease and HIV, are more prone to dandruff. For unknown reasons, people who recover after they suffered a stroke, heart attack or head injury are more likely to have dandruff.

Sometimes what appears to be dandruff can be a completely different condition. For example, lice can give itching and eggs of lice may look like dandruff. In addition, itching of the scalp can be caused by ringworm, a fungus that causes cell death and can determine the presence of white or yellow flakes, as in the case of dandruff.

Dandruff: a serious condition or just an embarrassing one?

Although dandruff can be embarrassing, this condition is harmless. It does not mean that you do not wash your hair or that you have dirty hair. Dandruff is not contagious.

In addition, it does not directly cause hair loss, but scratches can cause temporary hair loss. Also, for this condition, there are many shampoos that contain either natural substances or drugs that can improve or cure dandruff.
