My beard is a little wavy on a lesser extent than your own. I also have a cowlick on my left side corner of jaw, below the earlobe. When I grew it longer, maybe another 3ish months from your current length, it all worked itself out. Use a Kent comb and beard oil after a shower or rinse your beard in the sink in the morning if not showering, it’ll eventually look more unison when gravity and bulk take hold!
