Wahl trimmers are portable electric trimmers that simplifies beard and moustache trimming, as well as hair removal from the nose, ears and eyebrows. The line of trimmers includes the lithium ion beard and moustache trimmer -- and the nose, ear and eyebrow trimmer. The different grooming devices are designed for specific areas of the body, and run on nickel-cadmium batteries that last between two to five years depending on frequency of use.
Wash your face with a mild face wash and warm water to remove surface bacteria.
Dry your face with a clean towel to remove excess moisture and soften the hair of your beard.
Turn on the trimmers and gently run the trimmers with the grain of your beard's hair. The grain is the direction your hair grows, and reduces irritation caused by trimming. For the ear and nose, gently insert the tip of the trimmer into your nostril or ear without touching the skin, as the trimmer may nick the skin.
Turn off the trimmers and wipe the blade clean with a damp washcloth.
Drain the trimmer's battery once a month, and allow it to recharge for 16 hours, according to the official Wahl website.
