I get salon keratin treatments. My hair is also professionally colored. I have used Pureology Hydrate for years, as it is simply one of the best shampoos out there, but wow...it is SO expensive! I wash my hair three times a week and style it with heat less than a handful of times a month. I just really feel like I could get by with a less expensive shampoo/conditioner than Pureology. My hair dresser is not much help as she tells me to just get something that is sulfate free, but when I look at the ingredient lists, I see other things in them that aren't sulfates but according to what I've read, are just as stripping such as Sodium C14-16 Olefin Sufonate.
Does anyone have keratin treatments, colored hair, and use a shampoo/conditioner available for purchase from a drug store, Amazon, Sally's, or ? Thank you for any and all recommendations!
