So I qualified 2 weeks ago as a hair extension specialist in micro Nano and bonds. I had my first model last week and fitted her with 150g 20” (1g per bond) with copper tubes. She had had 30 fall out within a week what have I done wrong and why is their so much fall out?? Any suggestions? I just clamp like I would a micro ring. They also ain’t silicone lined. Iv purchased the micro rings (silicone lined) to reattached the ones that fell out is this also ok? Photo of completed hair below. She was my first model x
