think your wishing the wrong way
I think the majority here have the outlook for a nude barber backwards , i've never been to a real nude barber but had the opportunity to visit and get my haircut while I was nude a few times. best idea IMO is just find a friend that will get nude with you and you take turns being the barber or the customer . they're are several hair clippers on the market where you can cut your own hair or be lucky and have your nude friend cut it for you . hopefully they will for a tip trim or shave you bush too.
Being "hair challenged", I got some hair clippers years ago and quit paying someone to cut my hair. I live as a full time nudist and have an area outside set up for cutting hair, as well as a wet area for shaving body hair. Naturally, anyone who visits me is nude, so cutting, or shaving, each other is convenient. as well as fun.
awesome that's a great idea, I did the same especially during covid and now haircuts costing $20. + , amazon has hair clippers anyone can use themselves or a friend - no experience necessary. and body hair I have a bodygroomer I bought years ago that I or my bf can trim me smooth in 15 minutes . so many products out there now days .
