A set of three popular gels for all-wave perms. I used the purple and blue gels for the national exam. The blue gel is a firm gel used at the roots, and the purple gel was used from the mid-shaft to the ends of the hair. I bought the pink one to try it out. It's a great deal with a set of commonly used gels. Recommended for those who want to try various gels. All are opened. The purple one still has a lot left. The applicators were also actually used in the national exam. They contain the undiluted solution. I am selling these because I passed the 52nd national exam. *Please purchase only if you understand and agree that these are used and stored at home.
