I have a client with seriously bad nails after a bad case of over filing. (Not me previous salon) Her nails have lifted of the nail bed and are paper thin now. They keep breaking at the "free" edge and even half way down the nail she is having hairline cracks and they snag. I was thinking of doing a clear overlay with soak off so I can see that they are growing out okay. But I still want to give her a little bit of strength to the nails. My question is would I still have to build an apex with my clear overlay gel (OPI soak off) or just put it on like polish? And then normal polish on top?
