Your skin is constantly regenerating, but you generally don't notice because the skin cells you shed are too small to be seen with the naked eye. Only when a large number of cells are shed at the same time – as is the case with dandruff – are the flakes of dead skin visible.
Dry and oily dandruff
Basically a distinction is made between dry and oily dandruff. Dry dandruff is smaller and falls from the scalp. It occurs when the scalp is dried out or stressed.
Oily dandruff is the result of overproduction of sebum (seborrhoeic dermatitis or seborrhoea), which means that the body can no longer shed the dead skin cells. Instead they combine with the sebum, leading to clots of yellow dandruff.
What you can do about dandruff
If you only have dandruff fairly infrequently for short periods, the following tips may help:
- When you wash your hair, choose plant-based care products or anti-dandruff shampoo, and in general only use a small number of care products.
- You should also make sure the water isn't too hot.
- Afterwards dry your hair with a hair dryer only briefly, if at all.
- Avoid stress, which can trigger dandruff.
- Don't scratch.
If you start taking proper care of your hair but your dandruff persists and your scalp continues to itch, you should consult a doctor.
