how effective it is just that it has formaldehyde in it. This is my fault- should've checked the ingredients before ordering. :-/
Works well with regular use
I use this regularly and it clearly does help nails over time. My nails feel much stronger and you can wear alone or underneath your favorite polish.
Great nail strengthener
Love this nail strengthener, but the cap twisted off. I was able to sort of snap it back on but it still falls off. Still the strengthener dries fast and lasts a long time.
Great but not Special
This is a fine topcoat. However, I can' tsar that there is anything "special" about it. Not noticeably longer lasting or strengthening than any other top coat you may find.
Works too well
I started using this nail hardener because my nails were soft & peeling. After a couple of weeks I could feel that my nails were getting harder & weren't peeling anymore. But just as I was praising its abilities my nails started breaking whenever they came into contact with anything; the car handle, the dryer door, the dishwasher handle. Pieces of my nail were chipping off left & right. Now they are really hard & brittle. From one extreme to the other. Oh well.
