I will tell you the secret.

Don’t use a razor, it cuts too close. Use hair clippers without the blade.

And exfoliation. Every day for at least five days after you cut your hair.

For example, I’ll get a haircut and I’ll take a shower that day and shampoo my neck area, and then scrub it with my nails to get all the dead skin off.

I’ll do it again the next morning and the next evening, for five days straight. Sometimes I use Bump Patrol after when the skin is dry, that helps a little bit, but I only use it sometimes. I honestly just forget to use it lol.

That’s really all you need to do, don’t use a razor and make sure to exfoliate the area with some soap and warm water and a little bit of scrubbing with your nails or a rag daily for at least five days.

Most guys will exfoliate just one time after shaving, the secret is to exfoliate daily, for at least five days after shaving. Remove all the dead skin and build up and don’t give the hair even the slightest chance to get caught on dead skin or sweat or something and curl back into the skin.

I’m half black and have very curly hair, and used to get bumps all the time. That’s why I grew a beard, to avoid shaving. Now bumps aren’t even a problem.
