I have been working on another project - I finally quit my nail-biting habit and have gone about 2 months so far! Sort of. The only way I can keep from biting them is if I have some nail polish on them. I got 2 professional manicures but their results don't seem to last any longer than my efforts although they look much much better. Any tips and techniques to make your manicure last longer? So far, I have tried the 'natural' brands - Butter, Suncoat and Piggy paint but the results have been disappointing. What brands do you like? Color-wise I like the pearly opalescent neutrals.
