The nails pictured below are Tina's nails. Learning proper techniques was trial and error on herself. Once her nails were destroyed, She set out to learn how to repair them. Which gave her the skills to be able to repair anyone else's nails. She also perfected her techniques so you will never experience this damage at Chakras yourself! Tina used Aceso for one month to repair the extreme nail bed damage, and then switched to IBX for a month to get the repaired nails you see. She continues to use IBX.
