MANIC PANICClassic Shocking Blue Semi Permanent Hair Color - Dark Cobalt Blue Hair Dye for Women & Men That Lasts 4-6 Weeks - Vegan, Ammonia & Cruelty-Free - Create & Mix Custom Shades (4oz)

It turned my hair blue black which is exactly what I wanted. It had a blue sheen in the sunlight. I rinsed my hair in the kitchen sink because the staining is real. Not sure how long it’ll last but I’m impressed hair isn’t green.

It bleeds color a bit, but this is too be expected. Smells good, good coverage.

My hair needs a little break from lightening but usually colors do not take to my natural hair. which is a real pain to try to maintain. Tried this over 3my already lightened part with the roots growing out and I think it looks great. The hair that hadn't been lightened is a dull denim color, but I like it. I've done 2 clarifying washes and I'm stunned it didn't dull it out as much as expected. And where it had been lightened it is still blazing blue. As with all semi-dyes I know it wont last bright forever, but if you already know that's part of the cycle of hair this is one of the stand-outs for longevity.

This is a SEMI-permanent color, meaning it WILL fade with each washing. That's just the nature of semi-permanent dyes. I've used Manic Panic on and off for a few years and I like it a lot. Some colors work alright on darker hair colors, and if you check MP's website it'll say if you need to bleach it beforehand to show up. I took a gamble with this blue on my dark red hair and definitely lost that bet. Shoulda known better because this color was noted as needing light colored hair... But it was black! Like, totally black. I hoped maybe it would fade to bluer or even purple-ish as I washed it, but somehow it looked even MORE black! Mystery... When using semi dyes you can make it fade faster with heat and lots of washings or a hot oil treatment or (so I've heard but I'd be worried about overdrying my hair) some Dawn dishsoap. Also it will stain, like, everything. If the concentrated dye gets on fabric it's stained forever but I've found any light bleeding washes right out of towels, and a little bathroom cleaner with bleach will get rid of any stains in your sink/shower easily.

I've been using this ManicPanic since since 2009 - fun, easy, & my hair loves it. I have dark brown - going grey -curly hair and I don't bleach/lift my natural colors for this direct dye product. My results show in the image: the grey picks up lots of color & the brown darkens a bit with a blue overtone. If you're looking for a more even and deeper saturation of color on dark hair you'll have to lift it, and Manic Panic has a product for that. Using the right hair coloring accessories is vitally important: disposable ear covers, disposable head cover, coloring brush, gloves (suggest double gloving), petroleum jelly for hairline, special product for removing dye from skin, a color safe surface (it will permanently stain a lot of surfaces, so protect your sink & countertop), a hair dye cape (I use a large black plastic bag with holes cut for arms & head - funky but great value), a heat cap (the collapsable kind the use a hair dryer works well - application of heat stops color from bleeding onto fabrics, etc, once dry so I consider this essential), and sulfate free shampoo & conditioner. Sally Beauty carries a line called "ion" specially formulated for colored hair & it's excellent. Limit shampooing for longer color; cultivate 3rd & 4th day hair & when washing/rinsing use only cool water. I have read that subsequent applications of heated styling tools will change the tone and shorten the life of the color; the tradeoff is worth it for me. I avoid the high cost of salon coloring, the range of toxic chemicals that are in most permanent colors (for my as well as the planet), and deliberately shift my blue tone among the range of blue that Manic Panic provides. The image is of Shocking Blue. IF YOU GET THIS ON FABRICS - CLOTHES, SHOWER CURTAIN, TOWEL, etc - IT WILL NOT COME OUT! I have a black bath towel as part of my dye tool kit. Do not hop into the shower for the rinse out or your body will be streaked with blue! A stainless steel sink is perfect; leaning into a fiberglass tub/shower to rinse will result in a lot of tub clean up & the color might not come off that surface at all. You should read all of the directions to determine the best place for you to use this product.

I'm trying to add pop to my boring hair that's turning grey/silver more and more. I tried to dye it purple using another brands purple but it was more red than anything. So thinking blue + red = purple I bought this color. BLUE + Red = blue? I have zero purple but this beautiful blue is pretty nice looking in my hair but Every time I wash my hair I hate it more. Plus even after taking precautions everything is still Turing blue. My hands are blue after washing my hair and my tub bottom is alwYz going to be blue now. I woke up today and had a blue stain on my chest from my hair! I won't use it again.

Are you a brassy brunette like me??Did you dye your hair with a box dye and it eventually just turned an orange brown? Are you too dark/brown to use violet based toners?Then look no further!!!I bought this because I was tired of looking at my orange ends contrast with my dark roots. I’d used the JOICO titanium semi permanent before and that one is even better and toning brass ones because it’s a silvery blueish color. But I haven’t been able to buy it for over a year, so I tried the Shocking Blue and it works !! It definitely leaves it blueish but if your hair is my color—a 5-6ish brassy brown, then I recommend using it to tone it down.It came off a bit too blue for my liking, but I’ll do the rest of my head with it diluted in conditioner.See attached photos: I used it on dry hair, straight out of the container, left it for 30 min inside a ziploc bag (it was just a strand).
