It gives you energy, plus it contributes to healthy hair growth and hair color. A vitamin B-12 deficiency is associated with a condition called pernicious anemia, which is when your body can’t absorb enough of this vitamin. Your body needs vitamin B-12 for healthy red blood cells, which carry oxygen to cells in your body, including hair cells. A deficiency can weaken hair cells and affect melanin production.
