Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Sulphur has a long history of use in dermatology, and there is scientific evidence supporting its effectiveness in the treatment of dandruff and seborrheic dermatitis. Sulphur acts as a keratolytic agent, which means it helps to shed the outer layer of skin and reduce scaling. It also has mild antifungal and antibacterial properties, targeting Malassezia species, a yeast implicated in dandruff pathogenesis.

Clinical studies and dermatological texts, such as the Journal of Drugs in Dermatology and standard references like Fitzpatrick’s Dermatology, recognize sulphur as an adjunct or alternative treatment for dandruff. Over-the-counter shampoos and topical preparations containing 2-10% sulphur are available and have been shown to reduce flaking and itching in some users. However, sulphur is often combined with other agents, such as salicylic acid, to enhance efficacy. While not considered a first-line therapy (such as ketoconazole or zinc pyrithione), sulphur is still listed in clinical guidelines and reviews as a viable option, especially for individuals sensitive to other treatments.

Despite these findings, the clinical evidence base is not as robust as that for newer agents. Most studies are relatively old or involve small sample sizes. Nevertheless, the mechanism of action and consistent positive results in practice justify a moderate evidence rating for its use against dandruff.
