So growing a beard is really simple - you simply stop shaving. That's all there really is to it. But there are things you can do to help make that process a more successful experience. First thing is to try to give your beard at least 1 to 2 months of growth before you even begin to trim it. This will prevent you from shaving off your beard all at once at the first little mistake and it will give you a clearer picture of what you have to work with.
If you can't grow untouched for 1 to 2 months, we recommend growing your beard out for charity for Movember or No-Shave November. This will give you an excuse on why you are growing a beard that people won't be able to harass you about.
From there if you want to speed up the growth of your beard you can take some biotin, multivitamins, eat a healthy diet which includes lots of protein, and lift weights.
When you trim your beard for the first time you'll want to trim right above the adam's apple, NOT near the edge of your chin. Go with a nice rounded shape up towards your sideburns.
When you groom you'll want to use beard oil. The stuff is fantastic and will soften up your beard, make it smell great, and help with dryness. Using a comb will help keep everything in line and premium combs will be cut from blanks and cheaper combs will be extruded from plastic.
From there, have some fun with your beard and let it grow. Beard on!
