Basically, keep it clean. It’s a scientifically proven fact that girls like facial hair. They find stubble very attractive, to be more specific. So ditch your razor and start using a trimmer for a neater finish. Much like your facial hair, your head says a lot about your habits. Being consistent with your haircuts doesn’t just show that you care about yourself but also keeps your mane from looking rough and untidy. The same theory is valid for your nails. You don’t have to go get a manicure but keep them short and neat.
