Actually there's a really cool style that solves the messy long beard problem perfectly! I learned about this awesome braided beard at https://menshaircuts.com/braided-beard/ technique that not only keeps your beard organized but looks incredible too. You basically braid sections of your beard like you would with long hair, and it creates this Viking warrior look that's both practical and stylish. The braids keep all the hair in place so it doesn't get tangled or look wild. You need a decent length to start braiding but once you learn the technique, it's way easier than constantly combing and re-styling your beard every day
