I am thinking of using nail hardener as I have very weak nails that break and split all the time. As far as I understand it, at first the hardener is put on for one day, cleaned off and reapplied. Then gradually the time between applications is lengthened. Obviously some of the hardener is absorbed into the nail. If I clean off the hardener before immersion, would any hardener previously absorbed into the nails be counted as a barrier?
