Review of the Literature: Vitamin D and Hair: Should We Care After All?

The document reviewed the potential role of Vitamin D in hair health, particularly its impact on hair growth and regeneration. It discussed the modulation of hair-inductive capacity by 1α,25-dihydroxyvitamin D3 in dermal papilla cells, suggesting a therapeutic potential for hair regeneration. The review highlighted various studies that explored the relationship between Vitamin D levels and hair loss conditions, such as alopecia areata and androgenetic alopecia. Although the evidence was not definitive, the review suggested that Vitamin D might play a role in hair follicle cycling and could be considered in the context of hair loss treatments.
