I've recently gotten more serious about keeping my nails in good condition, as I've finally stopped my life-long habit of biting them. However, since it's taken me 21 years to start caring about my nails, they are not in very good condition. They have fairly deep ridges, and are very brittle and dry, and I was growing irritated when I'd give myself a manicure and the ridges would show throw the polish, making my nails look old and dry. I'd heard about this ridge filler treatment, and decided it was worth a shot. I am so happy that I tried it, it works marvelously! I don't have much patience when I do my nails, and I don't like waiting very long for them to dry (I always seem to get an itch somewhere!) and I was very happy to find that this base coat takes seconds to dry--and looks great just on its own, as well! Nail polish looks excellent and shiny on top, there are no traces of the ridges on my nails underneath the nail polish, and they look so professional! My nails also feel much harder and less brittle--much sturdier! I am so much more confident about my how my nails look, and much more invested in keeping them healthy and looking nice now! I am very glad I invested the money into this ridge filler, it is definitely part of my nail care regimin now!
