Scalp Seborrheic Dermatitis: What We Know So Far

The review article on scalp seborrheic dermatitis (SSD) provided an overview of this common inflammatory skin disorder affecting the scalp, highlighting the role of Malassezia yeast and sebaceous gland activity in its development. It discussed the association of SSD with telogen effluvium and androgenetic alopecia, particularly affecting men, with incidence peaks in infants and adults aged 30-60. The pathogenesis involved hormonal influences and environmental factors like humidity. Diagnosis was aided by trichoscopy, which revealed specific vascular patterns and oily material. Treatment options included antifungal agents, corticosteroids, and emerging therapies like cannabidiol shampoo and statins. The article emphasized the chronic and relapsing nature of SSD, the importance of individualized treatment plans, and the significant impact on patients' quality of life, while calling for further research to better understand its mechanisms and develop targeted therapies.
