Trimming tips

Trimming tips

• When trimming for the first time, start by using the comb with the maximum trimming length setting to familiarize yourself with the appliance.

• Since all hairs do not grow in the same direction, you may want to try different trimming directions (i.e. upwards, downwards, or across). Practice is best for optimum results.

• Always make smooth and gentle movements and be sure the surface of the comb always stays in contact with your skin.

• For best results, use the appliance on clean, dry hair, as wet hair tends to stick to the body.

• When too many hairs have accumulated on the appliance, remove the hairs before and/or during use, for best trimming results.
