Keep in mind that when it comes time to remove a weave where your natural hair has not been touched in approximately 2-3 months it is quite normal for you to have some shedding. On a regular basis or natural hair sheds 60-100 strands of dead hair a day. So if you haven't combed your hair in such a lenghty time it is only natural that all that accumulated dead hair will now shed. So, please do not be alarmed! My suggestion is to wait 2-3 weeks after your previous weave to get a new one. During this period you should wash, condition and trim your hair regularly, and try to avoid heat as much as possible. This will help to strengthen your natural hair. While you may undermine the intricacies involved in removing the weave, it is better to get it professionally removed.
