Hydrolyzed Silk is generally a lower-concern ingredient for seborrheic dermatitis. It helps hair and skin hold moisture and feel smoother, but it is not a treatment for seb derm.

A cosmetic safety review supports Hydrolyzed Silk in the uses and concentrations it assessed, while no direct human seb derm or ingredient-specific Malassezia evidence was found. Protein ingredients can still be unsuitable for an individual, so stop if a product repeatedly causes itching, swelling or a sudden rash.
