Middle Eastern & North African - If you find a guy named Ibrahim, you're golden.
High Tier
Filipino - My current go-to is an older guy named Marco. Not only does he deliver consistently great cuts, but his chats are top-notch.
Malaysian - only got one cut in Kuala Lumpur but the barber and the shop itself had an aura of professionalism that left a lasting impression.
Mid Tier
South Asian - worked with one guy for two years. Nice guy, but he leaned too heavily on high-maintenance styles and was the only one ever to nick my ear.
African (Somali) - Only had one Somali barber so far. He worked too fast and the scissor work was average. to give him to benefit of the doubt he's probably more comfortable working with black hair.
Bottom Tier
Slavic - My worst experiences have been with Russian barbers. Three out of three cuts were disasters.
MENA barbers here - ultra expensive zoomer haircuts. It's really just one guy knows how to do a fade and the others are FOB, they must have some scam where they can come here by saying they're barbers. None of these guys are trained to cut hair before they come here
Mexican (in Mexico) - so slow I was wondering if it was some sort of scam. He spent more than an hour touching it up. I think the scam was just that he wanted to have me sitting there in the window so it looked like they actually did business day-to-day and more people would come in. Haircut was good though
Slavic - also my worst haircut in recent years, believe the guy was recently out of prison and had no idea what he was doing. I looked like a shaved golf ball
Never had other haircuts from any nationality other than white.
The solid barbers here are white townies. My old guy before the pandemic was a "recovered" drug addict. Stopped going when he went back to rehab. Current main guy is a former roid abuser / competition bodybuilder who is just pretty good and not too expensive. Tried a new one recently who I will probably go to again - also white, kind of stern/scary but super knowledgeable, was able to look at my hair and tell me stuff I didn't know before - like some sort of hair astrologer. He seems just a little bit fashionable though so maybe gay. I'm getting maybe gay vibes.
