Fortunately I like dark red hair - that's what the 2 stars are for. This is what I ended up with. Absolutely nowhere near amber. The product was super easy to use and my hair is in great condition.

I recently dyed my red hair with 645 to even out some brassy roots which resulted from stripping out a previous colour. I have used this colour previously and for this exact same purpose. This new formula turned my red hair a warm but dark brown. This product is completely ridiculous and totally misleading.

I used amber expecting a copper red colour (like on the box) and ended up with a dark-ish brown that had a slight red tinge. I put it over my natural strawberry blonde hair. I really hope it washes out quickly. Definitely not the colour I was expecting.

I have used the amber semi permanent colour for a couple of years and was thrilled to find a semi permanent colour that suited me. However the 'new improved' version is far too dark and hair is not as glossy as it used to be.The end result does not match the colour indicated on the box, but it did before you changed it. I have now got to search again to find the perfect colour. Why on earth did you change a good product? Very disappointed.

This turned my strand test hair black. Mad at wasting my money . Thankful I didn’t put it all on my head, if I had I would be going nuts! I wouldn’t buy another product from casting.

I put the colour "amber" on my hair (which already had a ginger tint to it naturally) and my hair turned black!!! BLACK!! i am now going to have to strip my hair and damage it even further which is horrible because I have such long, unforgivable hair! I would not recommended this product

I bought this in Amber, which is an orange/copper colour. What happened on my head was straight up brown. And not even a very warm brown. My hair is medium brown with bleached ends. I have used other semipermanent colours that are similar copper shades and it warms up the brown and makes the ends quite orange - which is what I wanted. I actually quite like the neutral brown colour it turned out to be, but will not buy this product again as it is nowhere near what it's supposed to be.

I have short, light brown hair and had about half an inch of lighter root growth and about 7 white hairs in my parting. Not a god look so thought I'd try something new. The colour on the Amber box is absolutely gorgeous, just what I wanted, what I ended up with after following the instructions to the word is woeful, the only good thing I have to say is that it did cover the white hairs but the rest of it looks no different. A complete waste of 25 minutes, never again!
The conditioner smells nice
Ineffective and expensive for what it did - covered a few grey hairs but left the rest as it was.
