Urea is already a component of Kerasal (salicylic acid and urea) so why do you have to mix Kerasal with urea? Either salicylic acid or urea are safe for the nail but I doubt any therapeutic effect on your nail's condition.

It has recently been reported not all nail dystrophy problem with toe nails are caused by fungus alone. It has been shown bacteria are / can be involved
