Left: before. Right: after.
I expected a more pronounced result from the Chocolate color. Especially since I had it in the pack for 25 minutes. I think it can vary in strength depending on hair type. My hair doesn't hold styling particularly well and is uncolored from before. However, the product does what it promises - it refreshes existing hair color, makes it shiny and fuller. It has a distinct warm undertone which can be good to keep in mind if your hair is more on the cool side. My hair, despite the warm undertone, leans more towards the red side after using it. However, it lasts long, I would say a bottle lasts 3-4 uses. Unfortunately only three stars as I had hoped for a more marked result and a darker color as the name suggests!

Before: left and after: right. I expected a deeper darker brown from the color Chocolate. Especially since I had the color in for 25 min. The result isn't wrong, just not as pronounced as I imagined. I think it works a bit differently well on different hair. However, the hair feels shiny and a bit fresher. So the product does what it promises - a kind of reboost. I would say that this product is better for refreshing already existing hair color than for making a big change.
