How to find the perfect black shade for you:
Have you ever wondered what the hair colour numbers mean? The first number of a Hair Colour is how Light or Dark the brown hair dye will be, for example brown shades range from 4, Dark Brown to 6, Light Brown. 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
a year ago
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.

Greasy red mess
a year ago
I bought this yesterday & have been devastated since using it. It has dyed my roots red & has made my hair disgustingly greasy. Would never buy again.
