Best Natural Nail Strengtheners: Expert Recommendations

Question
What is the best stregnthener/hardener for natural nails. Mine peel and tear easily. Thanks

Answer
I recommend CND Toughen Up, along with either CND Supershiney or CND Air Dry.  Toughen Up is a formaldehyde-free nail strengthener that you apply every day or two;  you can use it over the top of existing polish.  I also recommend daily use of CND Solar Oil, which contains jojoba and vitamin E, and which will help keep your nail plates flexible (and your cuticles looking spiffy!).

Hope this helps!
