Loved the color, loved the product
My hair is about 7/ Blonde. Left the dye in for 45 minutes before washing out. Dried, it was a pretty teal color. It stained nothing but the t-shirt I was wearing at the time of dyeing. (It even washed off surfaces like the countertop and linoleum.) It bled a little every shower (turned the water a bit blue), but stained nothing (not my skin, not my towel, nothing). The first few showers (over the course of a couple weeks) there was little to no change in color. Then I noticed it getting lighter and more faded. Now, 5 weeks after dyeing, I think it looks a little gross, but my hair definitely still looks a little green-blue-grey-blonde. Like if you look up chlorine turning blonde hair green, but less vivid. I dyed about a foot of my hair and I still have some dye left over, so I might do this again!

Fanatic for Manic Panic
Instructions indicated 1 jar for every 4-5" of hair. She has 24" of hair. I didn't realize how much hair she has until we had committed to a budget. I used Manic Panic Flash Lightning 40 bleach. Best ever bleach. I used 4 bottles. We could have used 6. We ad 5 jars of color. Could have used 6 jars or more. Used 3 for initial coloring. Waited a week and used the remaining 2 jars for a touch-up. Not sure why we ended up with teal and not a darker blue as shown on the jar. Possibly we didn't use enough color. We are happy with how it is. The picture shows uneven areas. More color would have solved this. She has a tender head neither the bleach nor the color aggravated her scalp or skin. The aroma was pleasant. I didn't rate longevity as it is a semi-permanent color and a little washes out with shampooing. For 4 years we've used other products and have had hair colored by a salon so we have experience with the process. Highly recommended Manic Panic. Use the gloves and cap. Protect your clothes, use old towels. I spray the tub with Pam or something close so the color isn't absorbed into the finish.

Nice color, didn’t last long :(
The color was super pretty but faded super fast, as most blues due unfortunately. The color lasted about a month and faded into a green teal/grey which wasn’t the prettiest color. The dye smelled nice and was easy to clean up off of counter tops and skin.

Good color, but fades so fast and hair don't shining after wash
Why I gave 4 star... Why I gave 4 star... First coloration was great. but it fades so fast : ( I read some buyers wrote, that they don't wash hair often, I don't know how people walks with dirty hair. I usually wash my head every second-third day; after coloration, I try to wash every third day for safe color. After third wash, color didn't has shine... I was very disappointed... I use color safe shampoo, sulfate free shampoo and conditioner, they help me, but when I'm washing my hair and see blue water, I scare that I will be discoloured :( My hair goes green. Most of these problems, I disturb that hair didn't have shine :(

it must be the color, because it can't be the brand...
I've used Manic Panic multiple times, with multiple colors. I've never had a problem, whether it was purple, red, magenta or their toner. I mixed this color, along with some Atomic Turquoise and some conditioner for a cosplay and it looked decent when applying it. When I washed it out, the color was inconsistent and some parts didn't even seem to dye that well. Some parts were fully saturated while others were almost my natural bleached color. Two washes later and so much color has washed out, which is something that has never happened with any other color I've used. Is it just the color blue that does this?

Love this!
This product works so good! I have dark brown hair and had my hair professionally highlighted bleached, but the color was more of a golden blonde than a platinum blonde so I wasn't sure how bold this color would get. The blue turned out just like I wanted, nice and bold blue. I read about this product staining, so I put down towels on the bathroom floor to make sure any drops would not stain the tile and wore gloves while applying. I left the product on for about an hour and covered with a cap. I rinsed it out in the basement wash basin to avoid any staining the bathtub. After drying, my hair felt soft and in good condition and I love that it is a vegan product. I have long, thin hair, so this jar is enough to do just about 2 dye jobs. Much less expensive than going to the salon for a touch-up color. Will definitely use again and try different colors!

Terrible hair dye
This is terrible. It was recommended but a waste of money. I bleached my daughter's hair then used this. It looked great! She was happy! She washed it ONE time though with cool water and it was patchy and terrible. Not really washed out, but not really there either. We were left with the option of rebleaching or buying a different dye. (Splat for the win!)

LOVE IT
LOVE manic panic. I make sure its thoroughly in my hair (i use a comb to make sure i don't miss any spots) then i just leave it in my hair for about 3 hrs. Some times ill use a blow dryer. It is semi permanent, which i love. I will stain your fingers, so i would use gloves and be careful not to let it sit on any surface as it will stain that. Also as a tip, put Vaseline around the hair line and your ears, so it wont stain your skin. it will just wipe right off . Just gently wash it out in cool water and you're good to go :) I use a little bit of it mixed in with my conditioner when i shower, just to keep the color fresh. Since its semi perm, the color will wash out a little with every wash. I not only use this color, i use a few different colors. I will always use this product. :) the picture I posted is bad boy blue and teal, after about 4 in a half weeks of washing and no touch ups. I wash about every other day.

乾いた髪に塗って、暫く置いておく方が良く染まります!

いつもバットボーイかショッキングブルーを買ってます。基本的にホワイトブリーチしてから使っていますが。1ヶ月くらいはギリ維持出来ます。基本的にブルー系は色抜け早いですが。気に入っています。

Okay, some context- I had bleached and coloured my hair before, around beginning last year. It was the rainbow hair- green, pink, indigo, purple and blue. Only the blue remained (washing out seperate sections is really tricky). So this year all that remained was a lot of blond and light teal near the ends. It looked damaged and odd so I decided to use the manic panic blue to deepen the colour in the edges. It worked out amazingly! I put it all over (I have some greying near the roots too) and as you can see, it came out pretty darn cool. Added bonus was that it didn't bleed AT ALL! I remember all that unpleasant bleeding of colours on my back,dress and ears as I sweated. My fingers would be rinsed in colour , every time I ran them through my hair. And all that was a professional Salon work. This time, the towel that I used to dry my hair after washing the dye too didn't get any colour whatsoever. I put it on dry hair that I had shampooed a day back (no conditioner). I left it for a few hours 2-3. Rinsed it off throughly. My hair feels very clean and conditioned, so I didn't shampoo again. I have washed it since, it didn't bleed. So A++++++++++. One thing to note. It works better on bleached hair than grey hair. My Grey's got a transparent blue sheen but my bleached ends got an opaque blue colour.

インナーに使用。ブリーチ1回です。 肌についてもほぼ染まらず、バスルームが青くなることもないです。その分、ブリーチが甘いと緑になります。 自分は、ミスティックヘザーとまぜてつかっています。
