My nails look great! They're longer than they've been in years without assistance from gels and acrylics. They look healthy, and they feel smooth- my boyfriend is always marvelling at the fact that he doesn't "feel those little lines any more." My nails are now getting to the point where I'm chipping them on things because they're long enough to get between keyboard keys and bang on things when I'm doing day to day tasks like gardening and so on.
I'm finding that my nails are strongest if they get a dose of TIPS for Toes in the morning then some TIPS at least once, sometimes twice, a day. I tried a bit of experimentation to see if I could use TIPS exclusively, but I found my nails got little chips here and there if I did.
