Seborrheic Dermatitis Information
Seborrheic Dermatitis is a kind of skin disease characterized by the inflammation of the scalp or the face along with the appearance of scaly and flaky substance over the surface of the skin. It generally affects the areas of the skin which are in contact with the various glands present in our body. It is actually a more severe case of Sebborhea or skin eczema. One usually experiences a great deal of itching at the affected area and this causes further inflammation thereby making the affected area turn red in color.
Although the term ‘Seborrheic Dermatitis’ is also used in place of dandruff in many cases owing to the similarity of the nature of the skin disorders, yet they can be distinguished on medical terms. A person suffering from Sebborheic Dermatitis has an excessive oily skin with the growth of flaky scales and redness of the affected area. Whereas a person with dandruff only has scales over the scalp without the reddening of the area. Moreover as mentioned earlier, dandruff problem persists only on the scalp but Seborrheic Dermatitis may be caused at any place affecting the skin. So it can be of various types based on the location of occurrence such as Seborrheic Dermatitis of the scalp, face, chest, nose, ears, eyelids, or the chest.

- A yeast known as Malssezia globosa is considered to be the pathogen for Seborrheic dermatitis on scalp. Its presence is believed to cause inflammation of the scalp that toxifies the skin and causes further irritation. Its growth is supported by saturated fatty acids and triglycerides.
- Seborrheic Dermatitis is a condition that is quite often born out of stress related factors as well as poor health conditions caused by illness and fatigue. Men and women suffer from dandruff and erythemal problems especially due to psychological stress and sleep deprivation which in the later stage causes Seborrheic Dermatitis.
- The presence of Vitamin A in an excessive quantity causes hypo alimentation in both children and adults, thereby leading to Seborrheic Dermatitis. In the other way the deficiency of Vitamin B6 (also known as Biotin) as well as Vitamin B2 (also called Riboflavin) causes the appearance of scaly flakes over the skin and the reddening of the area.
- Those suffering from nervous disorders such as Parkinson’s disease and immunodeficiency problems are prone to this skin disorder. Moreover, a heart patient or a person tested positive for HIV may also suffer from Seborrheic Dermatitis.
- The drying up of the skin during winters may aggravate the occurrence of this disease. This is the reason why the people living in the cold climatic regions suffer from greater number of dandruff and seborrhea related problems.
