usually with black peoples hair if you have a crispy line and your hair starts growing ti can start looking ugly and tatterd/unkempt.
you basically need a shape up every 1-2 weeks, if youre wolfin (growing your hair out trying to get your waves deep)
i get liend up every week, but i get my actual hair cut like every month, because i have waves and i like to keep them on point... so i wolf for a long time to get the waves deeper...
when i didn't have waves, i got cut every week
