To get rid of hair bumps aka Razor Burn – you can try to use a mild exfoliant but do not scrub at it – you will also want to use aloe or tea tree oils or creams and I would not shave again until it goes away – give your skin a chance to heal. Also try preventing it in the future by showering and exfoliating first you can even use a loofah or shower puff. Prior to shaving the area cover the hair in conditioner and allow the hair to soften up a little bit first you do not need to rub it in just cover the hair with it (don’t let it sit more then 5 mins) then you can wipe it off with a hot washcloth and apply what you use to shave with (shaving soap) and try and shave in the same direction as the hair. Also keep in mind to try and hold the skin firm not too tight but you want it to be taut and only apply as much pressure as needed you do not need to apply too much pressure. I hope this helps! If you continue to have issues you may want to look into alternate hair removal products for sensitive areas.
