In my 101 things on the list is to strengthen and grow my nails. I've decided to hold off on the nail varnish for a few weeks (with the exception of a pre booked manicure next Friday). Mine are really weak after 22 years of biting them ridiculously low. I've tried most brands of strenghthener so decided to give OPI nail envy a go. Starting today I'm going to follow the instructions and hope it works.
