Hair Trimming after 2 weeks post FUE?

If you want to trim your hair two weeks post FUE, there should be no issue in general.  If you are concerned, contact your doctor.

Generally the wait time to do that is two weeks, when all the crusts have fallen. But since you still have some at day 18 then I would advise you to keep waiting until you have no more crusts. Be sure you are keeping up with regular washing, because they should have been gone by day 14 at the latest. Once the crusts are gone you are free to get whatever kind of haircut you want.

Hello. It is good to ask before hand. You can trim once the transplanted and donor area heal. This takes approximately between one to two weeks. If you see that everything up there is back to normal, then go for it. Most doctors recommend waiting at least two weeks to make sure your scalp healed completely.Best of lucks!

we usually suggest to get a haircut two weeks after hair transplant or when you are completely healed. 

Trimming the hair before all of the crusts are off is not very productive and runs the risks of dislodging the grafts.
