You can look in a mirror to gauge this. Get your hair styled first, then trim your chest hair to match it. Your head and body should look like they belong together.
Of course, you can also trim your leg and arm hair using clippers. This usually isn’t done unless you have a lot of hair in those areas. Don’t forget to proportion your chest to your stomach, too. Groom your stomach while you take care of your chest. Keep the hair the same length.
Put on a work shirt if you have one. Stay hairs can be a faux pas in a formal environment.
Body hair is natural and looks natural. Avoid trying to be someone you’re not. What’s important is finding out what looks and feels right for you.
There are some clippers marketed as body groomers. You can get this kind of electric trimmer or use the same kind of hair clippers you would use on your head.
It doesn’t matter if you start in the middle of your chest or the sides. Let personal preference be your guide. For tricky areas, such as around your collarbone and nipples, slow down. Move the blade downwards until you reach the area, then go around it. Reposition the blade as needed to reach any missed hairs.
As you get into a grooming routine, you gain a better understanding of which guard is the right choice for your situation.
Body trimmers often come with shaping attachments that make this easier. You could also use nose hair trimmers.
Experiment with your grooming routine! Hair grows back, so the consequences from a mistake are temporary.
A comb and scissors can be used instead of a trimmer.
You can shave in the shower if you have a water-resistant razor.
The cream or gel may slide off if your body is too slick. If this happens, pat your chest with a towel or air dry for a few minutes.
If this isn’t an option, use a fresh razor instead.
When you reach sensitive areas, such as your nipples, be very careful. Work around them. Adjust the blade’s angle to reach any missed hairs. Some men shave by moving up their chest, which is against the grain. This leads to a closer shave, but causes more irritation, so it isn’t recommended.
Try to limit the number of times you shave over spots as much as possible. Each pass increases the risk of irritation
