Has anybody tried this? I have some megamix and have a lady coming to me who's gone to an nss salon for 3 years and her nails are very soft and week. We're trying to get them back to how they were. Currently she's having shellac generally with a layer of silver vip or grapefruit sparkle to add extra strength. There lasting a week which is good for how bad her nails are but just wondered if a layer of megamix might make them last longer? If so how do I go about it? As far as application goes.... Thanks x
