here is the reply i got:

Hi Laurel,


This is Todd's wife Sarolta. I got him started on a
product called ONYMYRRHE 12 years ago on the tip of my
then beautician and it's worked great for him. The
bottle says: "A natural derivative of the myrrh plant.
This product fortifies and strenghtens natural nails
and is also recommended for ex-artificial nail users."
It is distributed by Tetra Pharmaceutical, Inc.,
Woodbridge, VA 22195. Todd gets it through a beauty
supply store.


Good Luck,
Sarolta
