My hair is more red tone as ive only ever done warm tones on my hair and i never planned to have cool tones in my hair, i bought it for fun and i just tested it out on a piece of hair and its amazing as it shows up beautifully blue!

This stuff is really pigmented, goes on smooth, and is a true semi permanent! Very little staining which is a huge plus.

Such a pretty, shockingly blue color. Stays, as in, not too quickbto fade with the correct shampoo and conditioner. I get compliments often.

Lighter and a lot brighter than pictures would lead you to believe! Basically if you want that classic electric blue - this is the color to go. On my experience with the Amplified formula: it doesn't lat any longer than a standart Manic Panic dye (which is generally around 4 weeks for me), BUT it does fade in a more graceful way - in fact it's one of the best fading blues I've tried. Absolutely no greenish tint, it just gets lighter and less saturated with a hint of silvery gray. Overall great dye and an improevment that's worth its money!

Beautiful color came out great on my unbleached light brown roots, only problem it washes out so fast!!! But color and application are beautiful and easy

I’ve tried several different colors in the blue-purple spectrum and I love them all. I haven’t used this one yet but overall I love Manic Panic products. They leave my hair feeling soft and the color holds up pretty well and fades nicely. Love that they are vegan with no animal testing. 💕

Really good for adding a touch of warmth to the tone when you're mixing blurs! Helps prevent it from fading too green, too.

I loved this hair color. It was my first time dying my hair, and I used the Manic Panic 40 volume lightener to bleach my dark brown hair to a very light blonde beforehand. The blue is super dark and vibrant after you first apply it, and stays strong for 1-2 shampoos. After that it fades to a vibrant purple, then pink. Love it!

Product description
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 Purple Haze to offset this effect. When mixed with Pastelizer, Shocking Blue becomes a gorgeous steely, blue-grey pastel shade! 
Our Amplified Formula contains up to 30% more pigment than their classic counterparts!
