Which deficiency is associated with hair loss, mood changes, and slower wound healing?

Explanation:
Vitamin D helps regulate hair follicle cycling, mood-related brain chemistry, and skin healing. When vitamin D is deficient, these systems don’t function optimally, which can lead to hair shedding or thinning, mood changes, and slower wound healing due to impaired skin repair and immune regulation. Other deficiencies might explain one or two of these symptoms, but vitamin D deficiency best accounts for all three together.
