I get a spiral perm every 12 -16 months since I have somewhat natural curly hair. My hair is long, thick and can be a challenge to detangle after a shower with a spiral perm. My hair dresser suggested I try this product after two weeks of my new perm. You really have to be careful when using conditioners with perms, as most will weigh down the curl and eventually the costly perm can be gone. I had used other Biolage products in the past, so I bought this one. Is made by Matrix and comes in a 13.5 fl. oz bottle with flip cap. It smells good, is a medium weight conditioner and really did the job. I only used a very small amount - like the size of a dime to nickel - on my hair and rinsed it out. I did a great job of softly detangling my hair without damaging my perm. I have such long and thick hair that my hair dresser has to use two boxes of perms, so I am very careful on what products I use. I suggest you give this product a try if you have the same type hair I do and I am sure you will be pleased with the results. I only use this product for a few months after my new perm and then switch over to AG.
