Vitamin D Levels Associated with Hair Loss

A new study on hair loss has shown that vitamin D can help reduce hair loss. According to NYU Langone Health, this problem affects more than 80% of men and 50% of women in their 50s.

In a new study published this week in the Journal of Cosmetic Dermatology, two dermatologists from India stated, “Vitamin D is inextricably involved in various signaling pathways for hair follicle growth and differentiation.”

Recognizing that vitamin D affects the hair cycle, they decided to conduct their own research on vitamin D as a “potential hair loss therapy.”

While this particular study group’s analysis did not provide evidence of a super-strong correlation between vitamin D deficiency and baldness, they cite one past study that showed a link between low vitamin D levels and “cicatricial alopecia,” a type of baldness. It affects 3% of hair loss patients in both men and women, according to WebMD.

Cicatricial alopecia occurs when hair follicles are irreversibly damaged and replaced with scar tissue.

A possible explanation for the role of vitamin D in preventing this type of hair loss is that vitamin D also supports skin rejuvenation, which may be a factor in scalp health. Vitamin D also helps to create more hair follicles. Other beauty and health experts also insist on the important role of vitamin D in hair restoration. As Rachel Cochran Guters, MD, recently stated in an episode of MindBodyGreen’s Clean Beauty School podcast, “Vitamin D is one of the fat-soluble vitamins needed to maintain and create functioning hair follicles.”
