I have been going to Kimi and had lash extensions for over 5 years. She is the best in Scottsdale. I recently met some gals that do lashes for a living and they were amazed that my lashes are still so thick. You shouldn't lose lashes from extensions if they are done properly with quality products. My real lashes are as thick as they were 5 years ago and I would highly recommend trying Scottsdale Lashes!
