Improper and irregular brushing of hair – When you brush your hair, you are giving it a way to shed dead skin on top of your head. When you do not brush your hair enough or do not air your scalp, there is no way for the dead skin to leave the scalp area. Accumulation of such dead skin can cause dandruff.
Allergic to yeast – People who have a yeast allergy or are very sensitive to yeast tend to have a higher risk of developing dandruff. By yeast, I do not mean the yeast that is used for baking breads. This yeast is a type of fungi or spore that flies through the air all around us.
Dry skin – Those of us who have drier skin than the rest have chances of getting dandruff. In fact people with dry skin report aggravated dandruff during summers when the skin gets drier still.
Certain illnesses cause dandruff too – It has been said that certain types of illnesses such as weak immunity, people recuperating from heart strokes, people affected by Parkinson’s disease and seborrheic dermatitis cause an increased risk of dandruff.
Infrequent shampoo wash – When we do not regularly shampoo and clean our hair, there is an excess build up of oil and dead skin on our scalps. When this excess is not cleaned away properly, it gives rise to itchy scalp and dandruff.
