Dandruff is most often caused by a fungus called Pityrosporum ovale (P. ovale) (also known as M. Ovalis or malassezia). P. ovale is a common and naturally occurring yeast-like organism found on the scalp and other parts of human skin.

When present in small numbers, this fungus has no harmful effects. However, in response to changes in climate, hormonal, or stress levels, the P. ovale tends to concentrate on the scalp- because it has the largest number of oil glands. P. ovale grow best in oil rich environments.

As the fungus grows, it increases the rate of cell turnover on the scalp- leading to the white flaking we know as dandruff.

How can you control dandruff?

• Use a medicated shampoo to combat the most obvious symptoms.
• Aim to reduce the stress in your life.
• Reduce the number of styling products you use, as mousse, hairspray, gels, and other products can make your scalp oilier- giving the P. ovale more place to breed.
