Hair and vitamin D
Vitamin D plays a significant role in hair health, and its deficiency has been linked to various types of hair loss. Here's how it connects to hair:
How Vitamin D Affects Hair
1. Hair Follicle Health:
Vitamin D stimulates hair follicles and may help maintain the hair growth cycle.
It activates hair follicle stem cells, encouraging hair production.
2. Regulation of Hair Growth Cycles:
It influences the anagen phase (active growth phase) of hair.
3. Immune Function:
Vitamin D supports a balanced immune response. An imbalance can contribute to autoimmune hair loss (e.g. alopecia areata).
Vitamin D Deficiency & Hair Loss
Low vitamin D levels have been associated with:
Telogen Effluvium (temporary hair shedding)
Alopecia Areata (autoimmune condition with patchy hair loss)
Possibly androgenetic alopecia (pattern baldness), although evidence is mixed.
