Recently grew my hair from shoulder length to MBL using a sew-in. During this time I would occasionaly go without the sew-in to rest in between. I told my stylist that I was thinking of just wearing my hair and stopping the sew-in. She told me to be prepared for major breakage. She said, "you will lose at least half the hair that has grown using the sew-in" Is this true? Her reasoning is that now I would be styling the hair with heat and it would be damaging and there is no way I will not experience breakage. By the way, the hair that is left out from the sew-in is shorter and looks chewed up and damaged.
