Itchy Scalp and Dandruff

Suffering from symptoms of an itchy scalp? Experiencing unsightly flakes of dandruff settling on your hair and clothing? You are not alone. According to statistics, up to one out of every four people suffers from chronic dandruff.

Dandruff is a condition that develops as a result of an excess concentration of the naturally-occurring fungus Pityrosporum ovale (P. ovale) on the scalp.

Typically, small concentrations of this benign fungus may be found on the scalp and in various other regions of the body without causing any harmful effects.

Such sites commonly feature a large number of sebaceous glands, these of which are responsible for the production and secretion of the body's natural oils; they also provide optimum conditions for the growth of P. ovale.

As a result, when the body experiences fluctuations in hormone levels, is under stress or is exposed to certain changes in climate or other stimuli, the production of such natural oils will increase in response, with consequent surges in the P. ovale fungus occurring at these sites. This acts as an irritant to the sensitive skin of the scalp and leads to increased rates of skin cell shedding. This phenomenon is referred to as dandruff.

As opposed to common belief, dandruff is not a genetic condition and may affect any individual at any age. Victims of dandruff may often suffer social embarrassment due to the common misconception that exhibiting an itchy or dry scalp and, consequently, dandruff directly results from a lack of hygiene. An itchy scalp, however, does not stem from dandruff itself but, rather, can be sourced back to an inflammation of the scalp arising from excess levels of the P. ovale fungus. In some instances, severe cases of dandruff may further develop over time into a condition known as seborrheic dermatitis, or seborrhea.
