NYK1 Purple Shampoo & Conditioner vaaleille hiuksille, sulfaatiton

My hair's been brassy for months and this is the first purple shampoo that actually toned it down without leaving my ends feeling like straw. The 1-5 minute leave-in window in step 2 is spot on—I do 3 minutes and my blonde looks fresh and cool-toned for days.

The instructions are easy to follow, and leaving it on for the full five minutes actually tones my highlights without drying them out. My hair feels softer than with my old shampoo, and the lack of sulphates is a big win for my scalp.

My brassiness is finally gone after just two washes, and the purple pigment actually penetrates instead of just sitting on top. The sulfate-free formula keeps my highlighted blonde from feeling like straw, which is a huge win since most purple shampoos strip my hair dry.
