Preface: I’m US based, I don’t know how barbers work where you’re from.

For me, finding a good barber includes having a conversation about what kind of things Im looking for. This can be as broad as “I don’t really know what fits me” or “I’m looking to go a bit longer so I can style it like this picture of a person with similar hair”.

After a couple of cuts, if I trust the barber can combine what I’m asking for with their skillset along with what they think looks good, I’ll tell them something like “look, I trust your style. You can cut it however you think looks good”. Their job is to cut your hair, but more importantly cut it in a way that makes you happy so that you keep coming back. A good barber will listen to you and get you a good haircut that gives you confidence :)

Good luck!
