Main Causes of Dandruff

Dandruff is a common skin condition of the scalp that affects most people at some time in their life. The condition is characterised by sensations of itching and burning and the emergence of dry, flaky skin on the scalp. Dandruff is actually a form of skin shedding and so is generally harmless, but the symptoms can be frustrating and aesthetically unpleasing. The reason dandruff is so common is that it can be caused by a variety of different factors.

Seborrheic dermatitis

When it affects the scalp, seborrheic dermatitis (or seborrheic eczema) can cause severe dandruff and make the scalp red, inflamed and flaky. This condition is caused by and overproduction of sebum, which is an oily, waxy substance secreted by the sebaceous (oil) glands. When this condition affects babies and infants it referred to as cradle cap. This form of dermatitis causes greasier flakes of dandruff, which are often larger and more noticeable than most other forms of dandruff. Seborrheic dermatitis can also affect other parts of the skin, as well as the scalp, where there are oil glands present.

This skin condition is the result of an overproduction of skin cells. Eventually this overproduction results in a build up of dead skin cells that form a thick layer of silvery-white scales. These scales often become itchy and inflamed and if they are disturbed they flake off. Psoriasis mostly occurs on the skin of a person’s knees or elbows, but it can also affect the scalp and surrounding areas. If Psoriasis only occurs on the scalp, it is often mistaken for seborrheic dermatitis.

Excess Malassezia

This condition is caused by oil thriving yeast called Malassezia, which naturally occurs on the human scalp. Due to it’s need for oil to grow Malassezia, like seborrheic dermatitis, thrives in areas where there are oil (sebaceous) glands. In most cases, Malassezia exists on the scalps without causing any problems, however, it can grow out of control and absorb too much of your hair’s natural oil. This irritates your scalp’s skin and encourages more skin cells to grow. These extra skin cells then die clump with natural oil from your hair and scalp, and flake off. Excess Malassezia is often identical to the appearance of seborrheic dermatitis.

Regardless of the cause, the symptoms of dandruff are very similar. Large flakes of oil coated skin that stick to your hair and scalp, and which flake of onto your clothes. These flakes of skins can be unsightly, irritating, not to mention embarrassing. If you suffer itchy or dry scalp use Clear.
