not ashamed to say as a guy, i get mine waxed / shaped, i also trim them down to stop them getting to thick/dense
it's another tool to add more definition and structure to our face, that we lose when no longer having hair. Bare in mind im someone who would otherwise have extremely wide busy brows that look drastically out of place
and i assure you, 99% of the bald celebs that you think look amazing with their bald heads, are likely rocking waxed / shaped eyebrows
