Not quite yet. I love him looking all clean, fresh, sharp and short

but am *considering* seeing what his hair would do if I did let it grow out a bit in the winter (this wouldn't be until November-ish if I do it).
But I have a question. I've always thought Jackson's hair would just not look right long on him, but the photos attached is the longest I've probably ever let it gotten. See how it's curly-ish?? Is that normal at that "stage" or do you think his hair would never be laying more flat down? How long do you think it would take to grow that out (he is usually shaved about every 10-12 weeks and it doesn't get
very long between the groomings).
He's not a cottony coat really... he never gets matted but he's not super silky straight either. My guess is modified coat? Not sure!
It just seems to me if I let it keep growing without getting it cut, it would kind of just poof out and never lay down the middle with a part... lol
