Barely any color at all

I followed the instructions exactly, apply on clean dry hair, leave for at least 30 minutes and rinse with cool water until it runs almost clear. Barely any color showed up and you can only see a difference if you look really closely. My hair is naturally a level 8 blonde and i expected at least some color to show up based on the chart on the official website. There was barely any pigment in the dye itself as well. As soon as I applied it on my hair you couldn’t see it. I knew it wouldn’t be as bright as on platinum blonde hair but this was very disappointing.
The hair on the right side of the picture is dyed and the left is natural.

Doesn’t take on, unless you bleach your hair into oblivion

I've been using another brand for years, but this one was on sale so I decided to give it a try. Won't buy again. It's easy to use and the color comes out just like the picture, but only on very BLEACHED hair. I have naturally dark blond hair, and I didn’t have to bleach it for the other brand to take to it. This one only worked on the ends and highlights that are bleached. So now I have VERY bright blue ends and highlights with a vomit-green concoction (with occasional orange spots) that is the rest of my hair. The picture I attached was RIGHT after I had just bleached and washed it. So this is the best you can hope for. Will have to re-dye it. On a plus side, it’s vegan and cruelty-free, which is awesome. (The brand I typically use is Colorista, by L’Oréal I believe. It takes on much better, and stays longer, not sure if that one is vegan though)

never again will I waste my money

got the lightening bleach kit.. worked great. im thinking wow finally I am gonna get some colour to stay in my hair.
after bleaching my hair was perfectly light. added manic panic and it turned a dark purple which I could notice in some light.. . ok I thought this is alright. it will do. washed my hair once (with cool water as the directions state) and bam. all the colour was gone. never ever again

We tried this a while back when it first came out. It was very time consuming and the colour didn't stay in after the first wash. We followed the directions but maybe it didn't work on our hair colour. Someone suggested we leave it in all night and add heat for better results.

This is a review for Manic Panic Raven, no other colour.

This formula must have changed in the last couple of months because I have never had such a hard time with this colour before and I've used it about 4-5 times. I always follow the instructions, buy the pre-lightening kit, wash hair, dry hair, slather it on, wait 30 min, apply heat...but nothing I did worked.

So here's the story. The night before I used Raven, I pre-lightened my hair as per the instructions. The following day I follow the instructions and apply the dye. After about 30 min and some heat to my head... I check to see if anything is happening. I do a strand test and the colour has taken... so just to be safe I leave it for another 30 min. After the longest shower of my life to get this colour out I proceed to blow dry and my hair is fire truck red. I'm panicking (haha) because I'm leaving in an hour, so luckily I had half a pot of this stuff left over and I go at it again... 30 min on the head with some heat, wash it out and... GREEN?! My freakin hair was forest green. Well this just sucks...

I go off on my business come home and buy a box of black/blue PERMANENT hair dye. My hair is finally a shade of black that I'm happy with, all this trouble for Cosplaying. Well it doesn't end there...

Now remember the permanent hair dye I used? Well the next time I went to wash my hair...it all washed out and I go back to having a green head of hair. Which later turns into grey (like old lady grey). After 3 months of dealing with this and trying to contact Manic Panic to figure out what happen (who, btw, have shitty customer service and blamed me for the whole fiasco) I finally decided to get my hair professionally done. Trying to get this manic panic out of my hair baffled all the colourist at the salon I was at because it just wouldn't come out. After 4 hours, my hair turning lime green and $500 later... I looked normal again. HOWEVER I have this gross band of a dark spot that wont take colour or darken or even lighten and no colourist can fix it.

Thanks manic panic for ruining my hair... don't buy Raven!!!
