So many times we’ve seen ugly white flakes on some people’s shoulders; maybe some of us have it too. Dandruff is an unpleasant and embarrassing problem for many people. That is why we need to learn more about seborrheic dermatitis, better known as dandruff. Is there a successful treatment? Are there natural remedies?
What Is Seborrheic Dermatitis?
The term seborrhea comes from the word “sebum”. This is the natural oil produced in the sebaceous glands that flows into hair follicles. Seborrheic dermatitis has been called a more extensive and severe form of dandruff, but there is no clear division between the two. Flaking, redness, and itching can appear on the scalp, in the eyebrows, around the nose, behind the ears, even on the chest and around the groin. It may interfere with hair health, resulting in partial baldness in severe cases. Sebum may also accumulate in the ducts of the glands, causing the glands to distend with un-discharged sebum, eventually forming into a small hard body called a “whitehead”. When the sebum in the mouth of the duct oxidizes, it darkens; this is a condition known as blackhead or comedo. 
The treatment of seborrheic dermatitis is similar to that of dandruff. However, a shampoo of coal tar seems to have a better effect on the scalp. If the problem is severe, you should seek medical advice, as a course of steroids may be required to clear it up.
Seborrheic dermatitis appears to be hereditary. Although dandruff may be the only thing standing between you and a closet full of basic black, know that you are not alone. At any one time, millions of Americans have this chronic scalp disorder, appearing as itching and excessive flaking of the scalp. 
Although dandruff is not contagious and is rarely serious, it can be embarrassing and surprisingly persistent. But the good news is, we can usually control dandruff. Mild cases may need nothing more than daily shampooing with a gentle cleanser, and stubborn flakes often respond to medicated shampoos. Moreover, researchers have identified a yeast-like fungus that may cause or aggravate dandruff. This discovery may lead to better treatments and eventually to a completely new wardrobe.
