QUESTION: Which vitamin deficiency causes hair loss?
ANS:
- Vitamin D is commonly associated with hair loss.
- Vitamin D is involved in regulating the hair follicle cycle, which includes
- Growth (anagen)
- Resting (telogen)
- Shedding (exogen) phases
- Vitamin D receptors are present in hair follicles; vitamin D influences the proliferation and differentiation of cells within the follicles.
- A deficiency in vitamin D may disrupt this cycle and lead to hair thinning or increased shedding.
