I'm trying to grow mine out.

every 8 weeks give or take. you need to get regular trim when you're trying to grow your hair or else your ends will become extremely unhealthy and when you do at last go in for trim, they'll have to chop a lot off. if your hair is really short now, you can probably go 4 months without a trim and not have bad ends. but if your hair is already past your collar, then you need to go in every 2 months or so just to get a tiny bit of ends cut off.0
