On the Treatwell website it said that my treatment (Calgel nail overlays) should last 1 hour 30. It lasted 30 minutes which was a little annoying as I had planned other appointments around it. I felt a bit awkward during the treatment as there was no conversation even though I kept trying. When leaving the salon I also noticed that some of my nails were s bit patchy. Won't be going back to this salon in a hurry!
