Dandruff, resulting from an accelerated renewal of scalp cells, accumulates in the form of visible flakes. It often causes itching, irritation, and a feeling of discomfort that can disrupt daily life. Its unsightly appearance can also affect self-confidence and social life.
The primary causes of dandruff include the overgrowth of the fungus Malassezia, an accelerated cell renewal of the scalp, excessive sebum production, or factors such as stress and an unbalanced diet.
Can stress cause or worsen dandruff?
Yes, stress can trigger or worsen dandruff by disrupting the balance of the scalp and promoting inflammation and the proliferation of the fungus Malassezia.
Can dandruff lead to hair loss?
Dandruff does not directly cause hair loss, but the itching and inflammation it causes can weaken the scalp, promoting temporary hair shedding.
Why do dandruff cause itchiness?
Dandruff causes itching due to scalp irritation, often caused by the overgrowth of a fungus Malassezia which releases irritating fatty acids by breaking down sebum.
What is the difference between dry dandruff and oily dandruff?
Dry dandruff is thin, white, non-adhesive, and easily falls off the hair, while oily dandruff is thicker, yellowish, sticky, and often remains attached to the scalp due to a significant presence of sebum.
