Why Do I Get Dandruff?

As previously noted, while its root causes are not clear, dandruff occurs when the skin on the scalp exfoliates excessively during the continuous course of skin layers replacing themselves, which results in large oily flakes, instead of the ordinary extremely small shedding. Therefore, it is assumed that the occurrence of dandruff might be related to some genetic factors such as excessive sebum (skin oil) secretion by sebaceous glands (oil-producing glands of the body). This is also found to be correlating with the observation that dandruff occurs mainly between puberty to middle-age, the phase when sebaceous glands are most active. Similarly, higher sebum levels in men, compared to women, may explain why men experience dandruff more often than women. 

Also, certain diseases that affect the nervous system such as Parkinson’s Disease or microorganism and fungal infections such as Malassezia globosa, a scalp specific fungus that lives on scalp are listed among the other causes of dandruff. Studies also demonstrate that there is a strong correlation between the increase in the severity of dandruff with the dry air of fall and winter months and the stress levels of individuals.
