Q: Is it true that stress can cause dandruff? What are other possible causes of dandruff?
A: Actually, while stress and dandruff are related in the level of severity of the condition, no studies have ever shown a causal link between stress and dandruff. The commonly accepted cause of dandruff (which is
medically referred to as pityriasis capitis) is the overabundance of the fungus malassezia (formerly called pityrosporum ovale).
Malassezia is a commonly-occuring fungus found in the skin of many animals, including humans, and is generally regulated by the bodyís own natural immune system and processes.
Sometimes, due to specific conditions (a personís naturally-oily scalp, environmental factors, etc.) the fungusí levels become excessive and cause irritation and the kills the skin cells of the scalp which fall away in
thicker, clumpier flakes.
As stated, stress does not cause dandruff, but as stress can inhibit the function of the bodyís immune system, it can cause conditions of dandruff to be more severe (if not outright
contributing to the imbalance in the level of the malassezia fungus in the first place).
