How often should I wax my moustache?

Moustache wax is a stiff pomade applied to a moustache as a grooming aid to hold the hairs in place, especially at the extremities. The required product strength (or stiffness) is based on whisker length and the desired style. It can also have restorative properties, which become more important as the hair length increases.

Generally less than a fingernail of wax is used when applied.
