Ignore the clean shaven boys. Embrace the beard!
Don’t attempt to do anything shape-wise for the first month. Then visit a good barber and have them shape it. Most folk cut the neckline too high and end up with clown face if they do it themselves.
Are you planning on a proper beard or something that doesn’t grow past the chin? Short beard, just scrub well to remove dead skin or you’ll get dandruff. Long beard, do that plus the below.
Get a decent balm (oil doesn’t give any hold) from Mariner Jack or Fellows, ditto for shampoo. Buy a decent comb (Kent are good) and a boar hair brush. Brush or comb once a day, apply balm every other day starting at the roots and working outwards. Use the brush or comb to finish. Shampoo once or twice a week depending on how oily your skin is.
Ignore the hipster jibes. I’ve had a beard for years, long before it became popular. Cut it last year and looked like the offspring of Moby and Casper the friendly ghost.
Remember, if you’re Dad hasn’t got a beard you’ve got two Mums 😉
