Vitamin D Status in Scarring and Non-Scarring Alopecia
Vitamin D is produced in the skin and is an important factor in the regulation of hair follicle cycling, which implicates it in hair loss.¹ Serum vitamin D levels are collected routinely during evaluation of hair loss, allowing institute clinicians to address this controversial issue.
Patients diagnosed with alopecia areata (AA), androgenic alopecia (AGA), central centrifugal scarring alopecia (CCCA), lichen planopilaris (LPP), and telogen effluvium (TE) over a 1-year period and not taking vitamin D supplements were identified (N = 358). Vitamin D deficiency was defined as vitamin D levels < 30 ng/ml, and were further categorized into mild (21–29 ng/ml), moderate (12–20 ng/ml), or severe (< 12 ng/ml) deficiency.²
Most patients had TE, followed by AA, and AGA. Median age was 49.5 years (range 4.2–85) with LPP patients tending to be older and AA patients younger (P < 0.001). Males comprised 9.8% (N = 35) of patients, and were most likely to have AA (P < 0.001). Vitamin D deficiency was present in 64.8% of patients, with 32.96% having mild, 17.60% moderate and 14.25% severe deficiency.
