Vitamins play a crucial role in maintaining hair health by supporting various functions related to hair growth, strength, and scalp health. Here’s how different vitamins contribute to healthy hair:
1. Vitamin A

- Sources: Carrots, sweet potatoes, spinach, kale, eggs, and dairy products.
2. Vitamin B7 (Biotin)

- Impact of Deficiency: Hair thinning, brittle hair, and hair loss.
- Sources: Eggs, nuts, seeds, whole grains, and legumes.
3. Vitamin B12
- Role: Essential for the production of red blood cells that deliver oxygen and nutrients to the scalp and hair follicles, supporting hair growth.
- Impact of Deficiency: Hair loss, thinning hair, and weakened hair follicles.

- Sources: Whole grains, meat, avocados, and mushrooms.
8. Folic Acid (Vitamin B9)
- Role: Helps in the production of healthy red blood cells, ensuring that the hair follicles receive enough oxygen and nutrients for growth.
