Nope, no cuticle, no colour retention. Yeah I believe if it didn't have cuticles it'd be very damaged. I think they do coat it in silicone though, just with the cuticles intact. If they coat it in silicone it doesn't matter whether it's cuticle correct or not because the cuticles can't catch on each other and get tangled because there's a smooth silicone to protect them.
So remy is nothing to do with the presence of cuticles, it does just mean they're facing the same way.
Bit of a myth about stripping the cuticles then.
