Hello ive not been doing gels long but have been getting great results lately in terms of no lifting and them lasting, so my confidence has plummeted today when a client I've been doing for a few weeks -( they've lasted long enough for me to do infills! ) tells me shd needs them taking off because a few of them are going green!!?? What causes this? I've not seen them yet but I'd like to sound like I know what I'm talking about! I use nsi gels
Thanks for any help
