Dandruff: For decades, the word ‘dandruff” has been associated with dry scalp, poor hygiene or using the wrong shampoo. Haircare companies have long marketed their dandruff-relief products with the messaging that it’s time to wash hair more often, switch products and moisturize better. However, medical science differs. Dandruff is a biological problem and not a hygiene problem.
Dandruff-The Myth Of Dirt And Dryness
Over decades, consumer behaviour has been primarily influenced by the belief that dandruff results from an unclean scalp. This has prompted people to over-wash their hair or aggressively scrub their scalp to eliminate flakes.
Dermatologists across the world repeat that dandruff is not caused by poor hygiene or dirt.

The Biology Behind Dandruff Flakes
This may come as news to you but this health condition is a complex interaction between the natural oil production by your scalp and a microorganism that lives there.
Human skin, including the scalp, hosts a wide range of microbes as part of its normal ecosystem. Among them is a yeast-like fungus called Malassezia that coexists harmlessly with its host under typical conditions. However, it may become a key player in dandruff in certain individuals.
The body’s sebaceous (oil) glands produce sebum, which is an oily substance that helps protect and lubricate your skin. Malassezia feeds on sebum, breaking it down into byproducts like oleic acid.
For some individuals, the scalp is particularly sensitive to these byproducts and the result is inflammation, irritation and an accelerated turnover of skin cells. Instead of shedding invisibly, these cells clump together with oil, forming the visible flakes associated with dandruff.
In other words, dandruff arises from an interaction between oil and microbes and not from a lack of cleanliness.
Rethinking “Healthy Scalp”
The transition from viewing dandruff as a hygiene issue to understanding it as a biological condition has important implications for haircare treatment. Medical experts recommend that individuals should focus on maintaining a balanced scalp environment instead of focusing solely on cleansing or moisturizing. This includes managing oil levels, supporting the skin barrier and controlling microbial growth.
