A sufficient amount of vitamin D promotes hair growth after hair loss

July 5, 2023 0 Comments

A single case report published in Annals of DermatologyA 7-year-old boy with reduced expression of the vitamin D receptor (VDR) in alopecia areata had new hair growth after six weeks2 daily use of a local analogue of vitamin D (calcipotriol). Full regrowth was seen after three months of use, and no hair loss was observed during the following six months.

“Vitamin D3 interacts directly with hair follicles, and when D3 levels are suboptimal, it can reduce hair volume on the scalp and throughout the body,” FWTS-certified trichologist and founder of Advanced Trichology, William Haunitz, told mindbodygreen.

considering 41% of US adults3 do not have sufficient vitamin D content and approximately 29%3 are directly deficient in the sunshine vitamin, a large portion of the population would benefit from supplementing with vitamin D if they want to grow their locks (especially after periods of hair loss).
