How many bottles will I need?
If you have short hair or are just looking to top up your colour, 1 bottle will do the job. We would recommend 2 bottles for lighter colours on short hair just so you can fully saturate each strand. 2 bottles for mid length hair - you need that full saturation and all important smooshing of the colour on your hair! Longer hair will need around 3-4 bottles to make sure every strand gets an even dose of colour.
Our bottles of semi-permanent are 100ml

Step By Step Guide
As with all of our shades, the lighter the base, the more vibrant the result! To get the best results, we recommend using our High Lift Bleach Kit. Use this shade straight from the bottle on pre-lightened, bleached blonde hair - check out our swatch guide and do a Strand Test to get an idea of the result you are going to get. You can still use the dye on level 8 hair, or below, but the results will be tonal.

Does your Slate hair need a little TLC and a colour refresh? Mix a few drops of your Slate semi-permanent into any Colour Care Conditioner, cover your hair with this treatment and leave for a few minutes. Not only will it soothe your dry hair but it will freshen those lilac tones too!
