Dandruff Treatments - symptoms, causes and treatment

Dandruff is a common skin condition. It's not harmful and you cannot catch it. Dandruff is a common chronic skin condition that causes the scalp to shed white or grey flakes of dead skin, that work their way into the hair and onto the shoulders. Once the flakes fall, they can become noticeable, particularly if they fall on to the shoulders, and this can cause sufferers some embarrassment and self-consciousness. The condition is not harmful or contagious, however it can leave people with a dry and itchy scalp, and it can be unpleasant and difficult to manage. Dandruff normally starts between the ages of 10 and 20 and is pretty common in people over the age of 30. 1 in 2 people in the world have suffered from dandruff at some point in their lives.

The cause of dandruff is a naturally-occurring microbe on the scalp called Malassezia Globosa. You’ll find it on everybody’s scalp, although it will only cause dandruff in around 50% of people. Here’s how it works: Malassezia globosa feeds on natural scalp oils called sebum – this oil is what keeps your hair and scalp moisturised As the sebum is broken down, it produces a by-product called oleic acid 1 in 2 people are sensitive to oleic acid and the scalp responds by becoming irritated In response to the irritation, the scalp starts to become inflamed, red and itchy The body signals to the brain to shed skin cells faster than usual – essentially, an attempt to shed the irritant. This shedding of skin is what causes visible flakes to appear on the scalp, often falling off onto your shoulders OTHER FACTORS THAT CAN AFFECT DANDRUFF While the root cause of dandruff is always the same, there are certain factors that can exacerbate a problem or make it seem worse. These include seasonal factors in summer and winter, external irritants like pollution and damage caused by our own actions such as too much heat-styling the hair. Everyone sheds dead skin cells all the time, including skin cells on their scalp. This is because new skin cells are continually being created to replace them and this process is healthy and normal. However, for people with dandruff, the skin cells shed faster than normal and the oil from the scalp (again, all people have this) clogs the cells together, giving this shedding the flake formation. Developing the condition can be caused by any number of things. If you have another existing skin condition (such as eczema or psoriasis), then this dryness could appear on the scalp too and you may notice it as dandruff. It could also be caused by a sensitivity to certain ingredients, like those in shampoos or other hair products. Dandruff isn’t just due to skin conditions though; it can be caused by a fungal overgrowth that can be triggered by too much oil on the scalp, problems with the immune system, hormones or stress. Causes of dandruff Dandruff is not caused by poor hygiene, although it may be more obvious if you do not wash your hair regularly. Stress and cold weather may also make dandruff worse.
