Explanation
A moustache is hair that grows between a person's nose and mouth. Some moustaches are as thin as a pencil line, while others are bushy and full. Salvador Dali was known for his long, curled moustache. If you're trying to grow a moustache, you might start by shaving all your facial hair except the strands that grow above your upper lip. When your moustache becomes luxuriant and ample, you can trim it with scissors and style it with moustache wax.
