Ensuring an adequate intake of niacin through diet or supplementation supports healthy blood circulation and, consequently, robust hair growth.
  3. Pantothenic Acid Deficiency and Dryness:
    Insufficient pantothenic acid can result in dry, lackluster hair. Since this B vitamin is involved in the synthesis of sebum, a natural scalp moisturizer, a deficiency can lead to dryness and increased susceptibility to damage. Including pantothenic acid in one’s diet or through supplements helps maintain proper moisture levels for healthier hair.
  4. Pyridoxine Deficiency and Hormonal Imbalances:
    Pyridoxine deficiency may contribute to hormonal imbalances that adversely affect hair growth. Hormones play a crucial role in regulating the hair growth cycle, and an imbalance can lead to excessive hair shedding or slowed growth.
