Had a client come a few weeks ago with color gel overlays asking for me to infil....this is her thumb nail..... she said she has been to a dermatologist and he has tested and ruled out everything fungal or bacterial and said its psoriasis...yes i agree that she does have psoriasis on her nails...(its very clear and obvious on her other nails)....but this nail is surely fungal...? I didn't work on that nail and advised her to get a second opinion.
