This product is wonderful! I've been using it for years. I don't dye my hair and it's wonderful at keeping me from going Grey. I am so disappointed that I can't find it anywhere anymore.

Thus did absolutely nothing for my hair color and I left it on for an hour and I have medium/dark brown hair with highlights that came out too light (almost blonde) and it looks exactly the same. Should have taken a before/after to post because it does do what it claims. All the positive reviews are clearly bots.

Sehr angenehm in der Anwendung und das Ergebnis ist top!! Bin sehr uufrieden und habe es bereits einigen empfohlen

I like this shampoo, but it did stain my tub for a bit and also stained my hands for some reason. I liked how my brown hair looked deeper and richer with this shampoo though. I would buy this again the next time I am shopping.

I dye my hair brown and love using this product with the matching shampoo, it really helps give definition to my hair which is hard to do as a brunette. It also leaves it feeling soft even though it's dyed and really helps maintain the colour.

Love the set, and how well it enhances color and makes my hair so soft and makes it feel so healthy.

My hair always seems to get this red under tone, over the past couple months I will use this shampoo and let it sit in my hair for a couple minutes and the red tone isnt so visible, much better then dying my hair to get rid of the red.

With dyed brunette hair, Ive not only wanted to maintain the colour, but also keep it looking bright and fresh between touch-ups. This shampoo & conditioner have made sure the colour had remained the dark brunette I was aiming for by working as a colour-protection AND refresher dye! Definitely something to check out if youre struggling with colour fading

I was really happy with the color payout on this, it extended the life of my hair dye

I loved how it made my natural brown hair have dimension and super shiny. Just wish there was a bigger bottle, I felt like it ran out quickly
