GUILT-FREE GLAMOUR!®

Shocking Blue AMPLIFIED is a dark cobalt blue hair dye. For best results, we recommend lightening hair to a very light cool-toned level 9 blonde or lighter. All semi-permanent blue hair colors can interact with yellow tones in bleached hair to create a green tint so make sure to do a strand test prior to applying all over to ensure you get the results you want! If you'd like to avoid a possible green undertone, you can add in a purple shade like  to offset this effect. When mixed with , Shocking Blue becomes a gorgeous steely, blue-grey pastel shade! 

Our Amplified Formula contains up to 30% more pigment than their classic counterparts!
