So I've had this problem for a long time, since maybe a decade ago, if you dont know what it means its when multiple hair shafts grow out of each hair follicle, personally most of mine have up to 6 growing from each. when I was under 20 I could usually pretty easily shave my public hair very easily but after a couple years it started getting to the point where I get so many ingrown hairs and infections that my genitals become useless and painful for weeks, I now just trim and keep it to about a cm length but I'm curious if anyone else has had this issue and found any remedies?

I like to do proper landing stripe. Are there any tips and tricks for it ? And how should maintaining it. Are there any other styles for easy maintenance.
