Ingrown hairs are caused by various things. However, this happens predominantly because the hair follicle is damaged slightly or there is a build up of skin in that area which prevents the hair from growing out of the hair follicle. The best thing you can do is exfoliate. The wax we use will also prevent damaging of the hair follicle as it pulls the hair by setting around it. Strip-style waxing can sometimes just snap or break the hair rather than pull it out which is a reason why some people get ingrown hairs more so with waxing. We can always try and get them out for you during your treatment as sometimes they can be tricky to get out yourself.
