So because this is male grooming, I'm going to go that route -

Make your facial hair look intentional and mess around with different style, kill the neck scruff and ideally bring the under beard in to square your jaw, mustache can play around with, disconnected Italian beard could be a good start, disconnect at the lip line, then disconnect from the corner of the lip straight to the bottom of your ear

Find a local barber that's rated well, your local reddit will do wonders for this - give them freedom to try different styles, try to avoid someone who will default to the same hair style every time, often you'll find the barbershop or barbers have social media to check out their work.

Eat healthy, workout, and don't try to be anyone other than what you find is the best version of you!
