Yes - eventually things seem to slow right down, but rest assured that your beard continues to grow and fill in. The curly nature of your beard hair will continue to help fill in the left side over time; I'm confident the process will continue - and maybe beyond another three weeks with your texture.

Even if you kept this length and look now - I think it looks great.

And yes....my beard and I were very happy in mexico - and less happy now at home with another 10cm of snow coming tomorrow!
