How can I stop ingrown hairs from appearing on my neck and the underside of my jaw when I shave please help me
Use shaving cream
Don't shave or use an electric razor instead. But once they're there, they'll stay there.
Use tweezers with sharp and skinny ends to pluck the ingrown hairs; which will take some time, and may be painful, or you can just let them grow out.There's also this site, which may help:http://mensfashion.about.com/od/groomingface/a/ingrownhairs.htm
Make sure you use shaving cream, also look for a cream that helps with irritation and bumps (acne) or an after shave.
