Apparently so..
It is possible for a 14 year-old boy to grow a beard or a visible mustache if they don't shave ?
Sure, for some. It wouldn't have worked for me. I didn't start getting my first facial hair until I was about 17.
I could go two or three days in boot camp whthout having to shave.
Yep ... But most of the time it's an ugly, scraggly thing that they would look better without.
Depends on your genes. Don't try beard tricks though it's an awful site with terrible advice, cheap and nasty which is why it is spamming all the beard questions on this site, free advertising, it's got to be cheap and nasty.
Well, I know that there are plenty of various brushes for all kinds of beards. They can be big or small, with a handle or not as well as with synthetic or natural bristles. What kind of brush will become perfect for you depends on your beard length... And type. Simply check this cool article about beard brush https://menshaircuts.com/best-beard-brush/
