I only use silicon lined beads with micro and nanos. When I first started out I put brown non silicon lined and also blonde silicon lined in the same persons head. The brown ones all fell out! I refitted with the blonde and No problem. Recently I refitted someone's hair (I hadn't supplied her hair) and the hair was all frayed at the top. I said the only way I can fit these is by using bigger non silicon beads that slip out a lot more. She agreed and then half fell out. I do someone's hair...
