Query: Just what the doctor ordered

I am 63 years old and have only had decent nails a few times in my life. They have always peeled horribly. I eat a healthy diet and take reasonable supplements so I knew it wasn't lack of nutrients. I asked my dermatologist if she could recommend anything and told me to always wear rubber gloves when cleaning or doing the dishes (something I often did, but not always) and to use Nailtique. It has worked perfectly. For the first time in years, I have perfect nails!
