What can i do to treat razor bumps for good?

Shave with grain: Best tip is to exfoliate before you shave, make sure you are using a fresh blade and a good shaving cream (not soap). Then shave with (not against) the grain. Won't be as close but will cause far less irritation. You can also apply tend skin after you shave as well.

Laser hair removal: Insure you use fresh, sharp blades vice dull blades. If hair is > several mm long – then trim before shaving. Wash area before shaving – warm water helps to soften hair. Use a lubricant when shaving. Avoid using products that contain alcohol or are scented. Shave in direction of the hair – not against it. Be gentle when shaving – don’t push down too hard. Moisturize skin after shaving.>
