First of all, start by filing the nails  to the desired length using an ANNY nail file. You should avoid cutting nails with scissors, since this causes the keratin layer to crack and split. In order to maximise polish durability, the nail must be free from skin cells, old nail polish,  grease and dust. This can be achieved using the acetone-free NAIL POLISH REMOVER. It’s also worth mentioning that nail polish should not be applied immediately after cleaning or a nail bath, since the nails store water and the durability of the polish is affected.
