  • Environmental factors, such as long stays in places with low humidity.
  • Psychological causes, such as stress or personal distress.

Can dandruff be prevented?

Dandruff can sometimes be prevented. It is important not to mistreat the hair with aggressive products and to reduce as much as possible the use of fixing gels, waxes and hairsprays, among others. It is important to use lukewarm water when washing the hair and to brush it regularly.

The treatment of dandruff varies according to the severity of each case, but includes various cosmetic preparations aimed at treating the cause of dandruff and reducing the symptoms of itching and redness of the skin. Usually, shampoos or solutions with an antifungal active ingredient, aimed at inhibiting microbial proliferation and combined with anti-seborrheic and antipruritic substances are prescribed.
