Caution is the ultimate glow up UV Yellow which glows in both natural light and backlight.
How Many bottles will I need ?
If you have short hair or are just looking to top up your color, 1 bottle will do the job. We would recommend 2 bottles for lighter colors 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 color on your hair! Longer hair will need around 3-4 bottles to make sure every strand gets an even dose of color.
Our bottles of semi-permanent are 100ml
Step by Step
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.
