Vitamin Deficiency

Key Nutritional Deficiencies Linked to Hair Loss

1. Vitamin D
   Vitamin D supports the creation of new hair follicles. Low levels of this vitamin have been linked to alopecia areata and general hair thinning.¹

2. Iron
   Iron helps transport oxygen to hair follicles. A deficiency can lead to hair shedding, especially in women, and is often associated with diffuse thinning.²

3. Zinc
   Zinc plays a role in tissue repair and maintaining hair follicle health. A deficiency can weaken follicles, increasing hair brittleness and breakage.³

4. Biotin (Vitamin B7)
   Biotin is vital for keratin production, a protein that makes up the hair's structure. A deficiency, though rare, can cause brittle hair and hair loss.⁴

5. Vitamin E
   Vitamin E is a potent antioxidant that helps combat oxidative stress, which can weaken hair follicles. Deficiency can impair hair growth and scalp health.⁵

6. Vitamin B12
   Vitamin B12 is essential for red blood cell production, ensuring oxygen delivery to the scalp. A deficiency can cause thinning hair and poor follicle health.⁶

7. Protein
   While not a vitamin, protein is critical for healthy hair, as it forms the foundation of keratin. A lack of dietary protein can lead to widespread hair shedding.⁷
