This product is for thin splitting nails.
I went to a dermatologist and he recommended this product.  I have been using it for several years; the trick to this product is don't quit after 6 weeks, keep using it for 8 to 10 weeks once a day and what a difference.  Make sure to use the cuticle cream comes in the box because the DermaNail dries out the cuticles. This product is worth the money.
