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 black hair dye will be, for example black shades range from 1, Deep Black to 3, Soft Black. The second number is the reflect which can be Natural (.0), Warm (.3, .4, .5, .6) or Cool (.1, .2). For example, 1.0 is a Natural Deep Black and 3.23 is a soft black with chocolate undertones. Always check the back of pack to see if it is the right shade for you.

Best at home dye out there

Always use garnier olia. No ammonia, no nasty chemical smell and the non drip application means no mess! I use to cover greys so use midnight black rather than soft black as I feel the dark pigment on this hangs on better to the greys for better coverage. Always on offer at Boots which is great.
Yes, I recommend this product.

Great smell, dark
a year ago
I usally but 1.0 as it's the deepest black but it wasn't at my store. Application was normal. As I was washing it out the water was green which isn't like the 1.0 shade. But my hair never looked green in the light. If you're blond I don't think this hair dye would be best for you because it could dye your hair with a green undertone. It came out very dark but not as dark as 1.0. My hair was silky, soft and smelt amazing. Opposed to when I use 1.0 and after drying my hair is wet with grease.
Yes, I recommend this product.

Never got to try it - due to poor gloves
4 years ago
I brought this July 2021 and never got to try it as the quality of the gloves was very poor. I have used a number of different dye products and never had an issue with gloves before. Maybe I should have tried the gloves before mixing. Each glove was 2 different sizes and split as soon as I put my fingers in. Now I cannot use the dye as it is already mixed and a big waste of money on my part. Please try the gloves first, before doing anything
