Seborrheic Dermatitis
Seborrheic dermatitis is a condition wherein dry, itchy and flaky patches occur on the scalp particularly around the hair margins at the back, sides and front. It can also occur at the sides of the nose, ears, eyebrows, eyelids and at the middle of the chest. It can also be seen in buttocks, underarms, groin, navel and breasts. Scaling and flaking can also affect inside the ears. This is a very common hair and scalp disease that can be easily treated.
There are three age groups that are commonly affected with this hair and scalp disease; during infancy, middle age and seniors. In infants, this is called the “cradle cap” and mostly it develops on the scalp. This need no treatment since it eventually clears between ages of 8 to 12 months. In some cases, it may develop in infants in the diaper area but it may also be confused as diaper rash.
People with oily skin or hair are the most commonly affected with seborrheic dermatitis and it can be caused by a yeast-like organism. This particular hair and scalp disease usually worsens for people living in northern climates during winter. This itchy condition usually does not cause hair loss but with constant scratching and rubbing of the scalp, the hair tends to thin around the edges. This condition affects almost 30% of the population and it usually come and goes with flare ups during the cooler and drier months. The flare ups can also be associated with stress and anxiety. Seborrheic dermatitis is not transmittable so it does not spread from one part of the body to another or from one to person to another. It is genetic so different members of the family can be affected from generation to generation.
