Can any list names of vitamins and what it does to the hair?


For example: vitamin A- then the definition on what it does for the hair.



biotin- definitely the best for hair, also nails, and skin. you have to take it daily but the good thing is you can't overdose on it, but be patient. it will make your hair shinier and grow longer. you will see an instant change in nails and your skin will look more "glowy"




biotin- after taking it for so long, it will help your hair get healthier and grow faster
