If you live alone and don't have help, you are going to have to use your sense of touch to remove sew-ins. If you have a full or partial sew-in and your hair has grown out, some of the things you would need are small scissors, a mirror, clips to hold back the hair, and a trash bin.
Stylist suggests clipping all of your natural hair out of the way to avoid accidentally cutting it. Then, slowly take your scissors to cut the thread that’s attached to the weft of hair — not the weft itself.
Once you get to the back, you will need to either use a mirror to see, or you can feel along the weft to ensure you are only cutting the thread. Once you have completely taken out the extensions, you will be left with the braid down. Depending on your hairstylist’s technique, it is possible that she may have sewn your hanging braids together with thread or she could have fed your hair into the next braid, or they could have crocheted the braids into each other. Either way, you would need to find where the end braid is and start unbraiding.
