Hi, I have trained with gellux,some clients all fab last 2 weeks goes on great, others doesn't last , and some colours just don't cure properly, I use correct lamp, thin layers extra.! I have also tried gelissimo which is a lot thinner, but clients nails when on holiday all went soft and then broke off! So can anyone recomend one please, don't mind spending money but really need to find one that works!!
