LOVE this product so far!
Just used the Color Pigment Refresher in Jet Black for the first time yesterday! I let it sit for about 10 minutes and my hair was noticeably darker. I think my hair was a little too damp when I applied the product (I have extremely thick hair). Next time, I'll probably get our of the shower and towel dry my hair before applying the product and let it sit for 20 minutes. My hair is super soft & shiny after using this product along with the SOS Shampoo & Conditioner.
BE CAREFUL! The product stained my shower walls even after rinsing it immediately after the product got on the walls. That's the only complaint I have with this product so far but not docking a star since Pallure is VERY clear that the product will stain.
