Dandruff is one of the most common scalp problems. But it is surprising that no precise cause off dandruff is known. There is therefore no cure for dandruff, but you can treat it whenever it shows. There are many factors that trigger dandruff and some speculation about the possible causes. Let us talk about them so that we can keep our scalp squeaky clean from dandruff.
Dandruff and fungus-
Dandruff is a kind of Seborrheic dermatitis and it is believed that dandruff is caused by a fungus that normally lives on the human skin and feeds on skin oils. During dandruff this fungus known as malassezia multiplies manifold and creates problems in the scalp. Why a fungus, which otherwise lies dormant, suddenly flares up and multiplies is not precisely known.
Dandruff and other causes-
Other causes that are held responsible for dandruff are – stress, poor hygiene of scalp, over use of shampoos, under use of shampoo, chemical treatments that harm the hair and scalp etc. the incidence of dandruff is less in summer than in winter. We can deduce that less sun may be causing dandruff, but exposing more to sun may cause serious skin problems.
