I've had HORIZONTAL ridges on my thumbs for years, and after years of googling the solution, I finally found it... All I had to do is stop pushing my cuticles before putting nail polish. Thumbs are especially sensitive to pressure, so don't press them! They disappeared completely and never returned. That was 10 years ago, and I haven't had a single ridge since!
