We have different vitamins for different things. When a cold starts rearing its sniffing, stuffy, runny head, you reach for a vitamin C supplement or double up on the glasses of OJ. You might reach for vitamin D in cold winter months when you’re not seeing enough sun. Collagen or vitamin E might occupy space in your cabinet to ease inflammation, aches and soreness brought on by your daily gym routine.
But if you’re struggling with hair loss, biotin can be a game-changer.
