The most important part of the styling is the wax. Waxing (applying wax, not painful depilation) will become part of your daily routine. Find a wax that works for you, and apply it liberally before leaving the house.
How to curl a handlebar moustache
Use wax by applying to your handlebar moustache with the thumb and forefinger, rolling the corners of the moustache out to a point. Over time the hair will continue to form the curl, but use wax for maximum effectiveness.
Trimming a handlebar moustache is a pleasure, not a chore. It should be undertaken every few days to ensure it retains its shape. Simply trim back any hairs that fall out of line and let the moustache fill out.
