Does exactly what it says..

Good product. My hair is white but dye it an ash blonde so it tends to get “orangey”. This shampoo does the trick.

I love this shampoo. I’m a natural blonde who gets highlights, and they do get brassy, as is natural. But this shampoo fixes that. It prevents any brassiness, keeps my blonde hair nice and bright, and delivers. It smells amazing. My hair gets super clean and I only wash it once a week. It’s high quality, thick shampoo so you don’t need much, it lasts a long time. The bottle doesn’t leak, as others have said, but I also don’t let shampoo residue build up around the opening that could prevent the cap from properly closing. I will keep buying this shampoo forever

Haven’t got my hair done in a while but it really brightens and refreshes the existing blonde.

I really like this shampoo. Allows my hair to be shiny, not dull, and not brassy. Cleans well today. Has a light pleasant scent.

I’ve tried countless purple shampoos over the years, but this one is hands-down my favorite—and I’ll definitely be repurchasing. If you have blonde hair and struggle with brassiness, this shampoo is a game-changer. It tones beautifully without drying out my hair, leaving it soft, shiny, and salon-fresh every time I use it. The pigment is rich but not overpowering, and I noticed a visible difference after just one wash. Plus, the scent is lovely—clean and subtle, not overwhelming like some others. It’s become a staple in my routine, and I genuinely look forward to using it. If you’re blonde and looking for something that actually works, this is the one. Total holy grail status.
