I switched to waxing as my poor delicate skin was sick to death of shaving rash, but I still get horrible ingrown hairs, looked at reviews for various solutions and one that stood out was Skin Doctors ingrow go, fab reviews, had wax yesterday and mentioned it to the girl doing it and she swears by it, so will let you know how I get on!
Now if anyone can come up with a solution of this 4 weeks growth in between waxing!
