I am 30 years old with no facial hair and was wondering if i can use minoxidil topical usp 5% to grow some?

You can try: You give your name as Sophia, a woman's name, but I only know what men have written about their experience. Some men have reported that this works. Smooth guys generally don't get male pattern baldness, and many women prefer it in any case. Regardless of your gender, fitness is the key to good looks rather than where you do and do not have hair. Best wishes.
