According to Debbies`site, Walker No-shine is rated strength 9-10 and gives 1 to 3 weeks holds. I use it for daily de-bonds but I only use 4 short strips [about and inch long] It releases quite easily with Lace-release..... one note of caution .... I heavily wet the hair 2 nights ago with water and then Enhance conditioner and the system tended to come free from the tape, so just be aware of that.... having said that, I really did wet it ..more than a light misting, as I was about to take it off for the night anyway....I like to leave the conditioner dry-in overnight..you`ll get your own little ways /likes in this game.....this stage will be the most `prickly` for you .....once your first 3 or 4 weeks are over and a de/re has been done more than once,you`ll learn to relax more with it all.
