Some of the steps a person can take to make their mustache grow thicker and faster include cleaning and massaging the hair follicles and sticking to a regular shaving schedule. It also helps if a person eats a well-balanced diet that is rich in biotin, vitamins B5, B3 and B9, and vitamins A, C and E.
Be sure to get plenty of rest each night, which will help the body repair injuries and grow hair. Reach for herbal supplements, including eucalyptus, mustard leaves, cinnamon powder and lime juice, or try some Rogaine. If a person has exhausted all home remedies, a trip to a physician can help eliminate any problems that could inhibit hair growth, including low testosterone.
