Redken Extreme Shampoo & Conditioner Set for Damaged Hair Repair - Sulfate-Free Hair Care Duo for Dry, Brittle & Color-Treated Hair | Salon Quality Treatment for Stronger, Healthier Locks at Home

You definitely get what you pay for when it comes to shampoo. Sure, you could find something cheaper but you won’t find anything that works as well as redkin. I have dry straight frizzy hair that breaks easily (but is thick enough to be a straight hair white person afro if I use cheap products) I also live in wisconsin so there is a lot of humidity in the summer and -40 temps in the winter. This is the only thing that consistently works. Redkin doesn’t let you down.
