I’d say the itching is just your beard getting back at you for all those years of shaving it, but that doesn’t really help. What I will say is something almost no one else will tell you: beware of cotton candy. It’s really hard to eat without making a sticky mess.
Still worth it, though.
For those who don’t know - this is especially funny because the reason I’ve never grown a beard is that I’m chromosomally challenged.*
*Female that is. 
It’ll stop itching in another week or two.

Eating soup is always a challenge once it’s grown in, too.
+1 to combing and gently exfoliating when you wash your face. You may also want to try a moisturizing face cleanser as well instaed of soap.
Ditto.
I get mine trimmed twice a year, when I get my hair cut.
