If you’re growing your beard more than just an inch or so, there’s one upside and one downside to dyeing it after you shave (which we still recommend). If you do it beforehand, you’re allowing light to penetrate your hair and showcase the ends. It doesn’t make a huge difference, but if you’re going to the utmost consistency, especially if you have light-colored hair, it can make it look a little 90/10, taking away from all the hard work you’ve done.\r
