Is seborrheic dermatitis contagious?

Scalp seborrheic dermatitis is generally not contagious.

Scalp seborrheic dermatitis is mainly associated with abnormal sebum secretion, colonization and reproduction of Malassezia, individual susceptibility, and some internal factors such as endocrine disorders. These factors are internal problems of the individual, not caused by external infection.

Secondly, it is not directly transmitted from one person to another by pathogens such as bacteria and viruses. Its pathogenesis is more complex than simple contact transmission.

Moreover, even close contact with people suffering from scalp seborrheic dermatitis, such as daily life contact, will not cause scalp seborrheic dermatitis due to such contact. Because its occurrence and development are based on the interaction of multiple factors of the individual. In

short, scalp seborrheic dermatitis is not infectious, and there is no need to worry too much about normal contact with patients. However, for patients themselves, attention should be paid and reasonable treatment and care should be carried out to alleviate symptoms and reduce recurrence.
