How to properly remove a weave without cutting or damaging your hair.
First, make sure your tracks are ready to come out. See If your braid is lifted from your scalp. If not it's possible that you will cut a portion of your own hair and usually a sew in can stay 4-6 weeks with proper maintenance. If it is lifted then this should be a easy process especially if you read my prior article "How to sew in weave". Doing it yourself you know they route in which you sewed.
Pull your weave up into a ponytail at the top of your hair. If you have a short style put clips around head. Take last track in the back and release from pony tail. This is the back of your hair some people can just feel the different between thread and there own hair. Place a mirror behind you so you can see the track cut one piece of the thread.
Start from where you cut the thread and lift remaining thread with your fingers. Repeat with rest of weave. You may have to make extra cuts but if you find where the knot is which is usually at either end and cut there then you can easily remove the weave.
