I have been using this for years but this time seems like the ingriedients have changed as it’s leaving my hair dry and brittle. It used to leave it super shiny before, I Used to get lots of compliments but now it looks dull with the same redken extreme. I habe curly hair thst I straighten thet used to stay straight and silky for 2 days.  Shane they have changed the ingredients.

I love the shampoo, I have very long hair so I do tend to go through bottles very quickly z I stupidly didn’t read properly and I guess assumed I had bought a shampoo and a conditioner but it was two shampoos so definitely lasting longer than normal. It’s great for thick hair too
