Review (5/5): super happy to have found this
I used to like the old purology but I like this much better. I was in a rut, complaining to my hair dresser that I could no longer make my hair smooth and healthy looking. After 2-3 months with this combination I am happy with my hair again. And, i can easily go a few days between washes which used to be hard for me.
My hair: 42, mostly gray, colored every 3.5 weeks and in the sun a lot!
