Hey everyone. I am using the bodygroom trimmer to shave my chest. I do not get acne on my chest but recently I have been experiencing ingrown hairs and bumps due to the new hair follicles. I only use the trimmer once in the shower. Can anyone give me some tips as to how to proper exfoliate or prep my chest hair before/after shaving to prevent ingrown hairs and bumps? I use a trimmer on my face and I don't have these problems.
