How do you get rid of and prevent ingrown hair around the pubic area?
If you wax or shave the region- you have to defoliate daily. If you don't shave or wax- you should at least trim the region so it is not overgrown and is more easily cleansed.
To defoliate you require either specialised defoliating sccrub cream, soap, brush or gloves and it's important to not scrub too hard or over do it- otherwise it will really sting.
Regular vigourous cleaning of the area will prevent skin overgrowing new hairs.
