Had a gel nail extension and it was one of the worst nail treatments I've ever had -the procedure was so painful my eyes watered, a "one hour" treatment took two and a half hours (which made me late for work), and the shaping was so bad I had to go to another salon to sort my nails out (forking out another £30). My nails were bent, bumpy, uneven and weak and three of them broke within 24 hours of the treatment. Not at all recommended.
