Fantastic stuff, the only treatment which has really worked for my overprocessed highlighted hair. But before you rush out and buy it, note two things - it's not a conditioner, and it only repairs damaged hair, not healthy.
Here is how I use it:
first I wash my hair with a clarifying shampoo (Nexxus Aloe Rid) to allow better penetration of the treatment. I towel dry and apply the Emergencee generously, combing it through my hair with my fingers. As I work it in, it changes texture from a sort of egg white slime to a drier feel. If my hair remains tangly, I add more Emergencee, until it can be worked through easily. I pile my hair on top of my head, and leave it for the recommended ten minutes (uncovered). I rinse it out, then, as recommended on the bottle, apply a small amount of regular shampoo (Aveda Rosemary Mint) dissolved in water to my hair. I work this through very briefly then rinse it out. This step changes the hair texture from straw like to soft, so it shouldn't be left out. Then finally I apply a moisturising conditioner (Aveda Damage Remedy), then rinse this out.
Before using Emergencee, my ends were dry, frizzy and tangle prone. My hair had a strange chewing gum-like texture when wet, and took forever to dry. It improved visibly after the first treatment, and after four or five weekly uses, it is now strong, shiny, and generally healthy looking and feeling. Although this is expensive, if you have damaged hair, it is a godsend, and worth every penny. I recommend using in conjunction with Aveda Damage Remedy conditioner and treatment for best results.
