A natural moustache is any length of hair grown from above the upper lip and beneath the nose, with no styling products permitted. The moustache hairs should be connected up to a maximum of 0.6 inch (1.5 cm) beyond the edge of the upper lip.

No styling aids permitted. Acceptable styling methods to be used with a natural moustache include brushing, combing, conditioning, and shampooing.

Chin hair is not permitted in this category: no “goatees”/van dykes, musketeers, etc. Sideburns unconnected to the moustache are permitted. They cannot be overstated, and will not be considered during judging.
