Until recently, I used to take vitamin A capsules for my hair nutrition as prescribed by the doctor, however, one of my friends has advised me to use energizer vitamins and minerals for hair nutrition. Moreover, she advised that along with hair, it also would be useful for great skin as well! Nonetheless, I want to confirm, if I should eat it in the evening after sunset, as I used to take vitamin supplement only in the evening as advised by the doctor. Please advice.
