Ingrown hair problems

Okay ladies, so I've been suffering from ingrown hairs for quite some time now . I'm super sensitive down there . I've tried numerous of things to help prevent getting them but nothing seems to work . I've tried different shaving techniques, different razors , shaving products & also waxing . Waxing has helped but hasn't completely cut them out . I get at least anywhere from 2-4 ingrown bumps each month . Please helpppp and comment below of what works for you .
