What causes dandruff?

Dandruff is not common in adults. It is estimated that about 1 in 3 people suffer from it. But do we really know where they come from? We explain to you the causes of dandruff to better understand this hair problem.

What is dandruff?

Dandruff takes the form of small white flakes. Unattractive, it can also cause some discomfort. And for good reason, they can be responsible for itching and red spots on the skull.

They are actually scales that separate from the scalp, ending up in our hair or even on our shoulders (and clothes).

This dandruff occurs as a result of excessive flaking of the scalp. If it is a mild illness, it can be caused by various factors… and some of them are treatable! This is why it is important to know the cause in order to be able to act.

Different types of crust

You should know that there are two types of dandruff:

  • Dry dandruff: It is caused by the dryness of the scalp. This is the most common dandruff, it does not always itch.
  • Oily dandruff: It is caused by excessive sebum production. These cause more itching as they stick to the scalp due to the sebum. It could be responsible for hair loss.

Dandruff: its causes

We told you the causes of your dandruff are various.

Indeed, you should know that most dandruff appears due to cell regeneration. Every 28 days, our skin renews itself and removes dead cells. However, in some cases, a fungus called pityriasis head (which we all have but often remains inactive) wakes up and leads to an imbalance of this regeneration. The latter is accelerating: it runs from 15 to 7 days, instead of 28. Dead cells do not have time to get rid of them and a lump forms .. which gives dandruff.

Some factors can promote pityriasis:

  • stress and anxiety
  • Regular rubbing of the scalp (hat, cap, etc.)
  • Frequent use of heating devices
  • Frequent use of hair fixing products, type varnish or gel
  • high body temperature (fever, etc.)
  • Bad lifestyle (tobacco, alcohol, unbalanced diet)
  • Inappropriate hair routine
  • hormonal disorders
  • Gastrointestinal Diseases

Namely: Dandruff can also be caused by skin conditions such as seborrheic dermatitis, eczema or psoriasis.

Rest assured, some remedies are effective in getting rid of these white flakes. There are also natural remedies to fight dandruff.
