Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Vitamin D has some scientific basis for its use in supporting or treating dandruff, although the evidence is limited and not as robust as for other dermatological conditions. Dandruff is primarily associated with seborrheic dermatitis, a chronic inflammatory skin disorder often linked to the overgrowth of Malassezia yeast on the scalp, as well as disturbances in skin barrier function. Vitamin D is known to play a role in skin health, particularly through its regulation of keratinocyte proliferation and differentiation and its immunomodulatory effects. Deficiency in vitamin D has been associated with various skin conditions, including psoriasis and atopic dermatitis, which share some pathophysiological features with dandruff. A few small-scale studies and case reports suggest that topical or systemic vitamin D analogs, such as calcipotriol, may help improve seborrheic dermatitis by reducing inflammation and normalizing skin cell turnover. However, most of these studies are limited in scale, and direct evidence linking vitamin D supplementation or topical application specifically to dandruff reduction is sparse. Observational research also notes that people with seborrheic dermatitis often have lower serum vitamin D levels, but causality has not been clearly established. Overall, while there is a scientific rationale and some preliminary evidence supporting the use of vitamin D in managing dandruff and related conditions, larger, high-quality clinical trials are needed to confirm its efficacy.
