[header] How to shave chest hair [title] Trim your chest hair outside of the shower. [step] You wouldn't take a cartridge razor to your beard before trimming it down, and the same can be said for shaving any body hair. Start with a trimmer on the shortest setting to give you better visibility and necessitate fewer strokes when you go for the razor. <sep> (A) [substeps] Make sure you trim with completely dry skin and hair. Wet hair will stick to your chest making it harder to trim, and it can also stick to the trimmer. (B) [substeps] Plan to shave just above your ribcage or a little below your armpits. [title] Shave under or below your collarbone or behind your ears. (C) [substeps] Be sure that you go for a length that's short. If your hair is too short, the trimming will look unnatural. (D) Also trim a few inches from your waistband as well. [substeps] Lice aren't very visible, so shaving in the shower is less important.
