Abstract in brief

Vitamin D plays a crucial role in skin health and hair growth by regulating immune responses, inflammation, and the behavior of hair follicle cells, with ongoing research into its impact on hair loss.
Most studies indicate an inverse relationship between vitamin D levels and types of hair loss like telogen effluvium, androgenetic alopecia, alopecia areata, and trichotillomania, suggesting that deficiencies may be linked to these conditions.
Despite its potential, there is currently insufficient conclusive evidence to recommend vitamin D supplementation as a standard treatment for hair loss, and further research is necessary.]

@THAKUR4YU5H @FitFounder Yes, it would be a good idea. It’s also a good idea to get your levels checked if you’re taking large amounts (8000iu+ a day) after 3/6 months. https://t.co/lJ1lyCQO2X

@Arwenstar Could be linked to a Vitamin D deficiency. It's a very common side-effect, and easily fixed. Oh, and don't forget Vit K2. They work in synergy. https://t.co/3RZXHYTVtt
