Myths about Dandruff
Dandruff is due to dryness of the
skin.
False. Dandruff is caused by a rapid turnover of cells, so
more dead cells are shed from the surface. In fact, dandruff
occurs in areas where the grease glands of the skin are most
active, and the skin is not usually dry.
Dandruff is more common in males than in females
True. Probably because the grease glands are affected by
hormones.
Dandruff is affected by the weather
Probably true. Sunlight inhibits the growth of the
Pityrosporum ovale yeast.
Dandruff results from poor hygiene
False. Dandruff is caused by rapid turnover of skin cells,
probably as a reaction to the Pityrosporum ovale yeast.
However, dandruff sufferers do not have more of the yeast
than other people - they are just more sensitive to it.
Dandruff is contagious
False. You can’t ‘catch’ dandruff from someone else, such as
by using his/her brush or comb.
Wearing a hat worsens dandruff
Possibly true. Pityrosporum ovale yeasts thrive best when
protected from sunlight. Also, wearing a hat prevents sweat
from evaporating, and this may encourage the yeast.
