Nailtek works wonders. They probably have it at your local nail salon. You put one coat on per day until day 7, and then clean them off and start over.
Unfortunatly the ridges have to grow out, but you can save your nails by putting hardeners on them. I had acrylic for 7 years, and am now acrylic free, with no ridges or pain, and my nails are twice as thick as they used to be. NAILTEK thank you!!!!!
