Hydrogen peroxide in bath water for ingrown hairs down there?

I saw a post on Facebook about all the ways that hydrogen peroxide can be used and one said to add a bit to your bath water to help heal boils and skin issues. Have any of you ever done this to help heal ingrown hairs down there?? The bottle i have says do not put on large areas of body but what about just a little mixed in the bath? Im wondering if it is safe and works. Thanks
