I don't know what to say. My nail use to grow 2mm every month. Now it has stop growing completely. I used to use Sally Hansen products especially the Sally Hansen maximum or the Sally Hansen cuticle and moisture treatment pen for the last 6 years but this year 2019 my nails broke off and has not grown back and it has been 7 month now. I'm thinking maybe my iron could be low but can some one help me.
