The second number is the reflect which can be Natural (.0), Warm (.3, .4, .5, .6) or Cool (.1, .2). For example, 4.0 is a Natural Dark Brown, 4.3 is a Golden Dark Brown, and 4.15 is an Ash Dark Brown. Always check the back of pack to see if it is the right shade for you.

Left with a patchy mess

8 months ago
Awful hair dye!! Used on my dark blonde/light brown hair, followed all instructions and left on for the correct time and I’ve been left with an awful patchy mess! Colour is nothing like what’s on the box and it’s turned my roots a reddish brown colour

No, I do not recommend this product.

Really easy colour to use and it fades beautifully if - like me - you’re not super on it with your colour upkeep! I love the conditioner that comes with it and use it for a long time after I’ve done the colour.

Yes, I recommend this product.

Beautiful colour

It has a warm mahogany reddish tint, I love the colour. I have natural dark brown hair and I put this colour on to cover some blondish highlights I had done- did the job brilliantly and gave my hair a bit of a red tint which I love.

Yes, I recommend this product.

No, I do not recommend this product.
