I’ve been using NSI for just over a year now on myself and since July I’ve used it for mobile work. However I find a lot of my clients tell me they don’t last longer than a week!! Obviously I am gutted and get so embarrassed because of this (I always offer new nails for free) but it’s getting to the point where it’s more often then not and I would like to know if it’s what I do or if it’s the system or other factors as some clients it lasts 3/4 weeks inc myself! I buff the nail, dehydrate then prime with the super bond primer and use tips but these are just cheap ones from amazon then use the acrylic system and file with hand files and gel over top... is it the tips I’m using?? Or something else? Advice would be great tia xx
