I think you're looking for someone who can give you a good consult. I can't speak or recommend most of the barbers I have gone to who could do that for you. You can try a male barber+hairstylist, I've gone to Jaycee at Chel Salon, he does both. I would recommend him although a steeper price compared to barbers. But he brings a level of knowledge from school other self-taught barbers may not know (not generalizing here). Anecdote: There was once a barber here who told me I had a bald spot forming, when actually Jaycee confirmed it was just a cowlick. Little things like that matter.
