Classic Rockabilly Blue Semi-Permanent Hair Dye (118ml) | Neutral Blue Hair Dye for Women & Men That Lasts 4-6 Weeks - Vegan, Ammonia & Cruelty-Free - Create & Mix Custom Shades

Good quality. Amazing colour and last really long

A brilliant bright blue! Looks great, after one wash it looks the exact same unlike other blues I’ve used before. Does stain a little bit so try to avoid your skin as best as possible but that’s expected

I really love the effect of this blue dye—extra points for being vegan! In this case, less is definitely more. It’s best to apply the dye using a comb, just on the hair, to avoid staining. The colour stays on the skin for about a week, and on fabric forever, so be careful with your clothes—my white pillow with a red pattern is now mostly blue! For the next 4 weeks, don’t be surprised if the water turns blue in the shower. Avoid wearing white or very light shirts or tops for 6–8 weeks if you want them to stay that way. I absolutely love my new hair colour, but fair warning—I had to bleach my hair myself to get this result. I’ll definitely order again! For my short hair, I’ve reapplied it 4 times from this little container (every 4–6 weeks), and it looks like there's still enough left for 1 or 2 more applications.

I have dark brown hair with a single blonde streak, that never takes any colour unless I bleach it first. After watching all the videos (the one on the Manic Panic website is worth watching) I left the dye on over night. Results were brilliant. the blonde (and grey!!) in my hair turned dark electric blue the rest deep midnight blue. There is a kind of green tint to the colour in certain lights but its only slight- I do not look like She Hulk. It did leak through my gloves a bit and stain my fingers (scrubbed off with nail polish remover!) but didn't stain my shower (just give it a once over with detergent and it comes clean off- some plastic surfaces may stain though) and I didn't turn in to a smurf (obviously if you stand fully under the shower to wash this out you will go blue. Not sure why people have complained about this???- wash JUST your hair with the shower head!). The colour does bleed a bit when you wash it (currently 2 washes in) and send your hands a tiny bit blue but it is not a permanent dye so you would expect this and the blue on your hands comes off pretty easily so its manageable. It has not damaged my hair in the slightest (mostly made of veg I think) so I would feel totally at ease using it again in a few weeks. I totally recommend it and will be using it again.

This is my hair after a few weeks after dying it, I used purple haze and I think the blue was rockabilly blue, I mixed it with a little conditioner and let it sit on my head under a shower cap for a few hours before rinsing with ice cold water. the first week my fingers and nails were blue from touching my hair and the blue rubbed off on everything which is a classic problem with manic panic but I can’t fault the colour, it’s been a month now my hair is still very vibrant only fading in a few places mostly my roots (second pic is after a month). I wash it once every 5-7 days with ice cold water over the tub and use olaplex shampoo& conditioner I’m honestly obsessed won’t go back to box dye EVER

It works good and can see colour brightly but if u have unbleached brown hair it goes kinda green. I like it but it’s not like it said

Big Fan of this product, highly pigmented colour and doesn't damage hair

Sooo bloody happy soooo blue

Thank u

So far I have used the Rockabilly Blue, Enchanted Forest, and Violet Night on my virgin light brown/gray hair without bleaching first. I first washed my hair with Prell to get all the residue out and rough up the hair shaft a little so it would take the dye well. I did not use conditioner. Then I applied the dye and left it on for 8 hours, under a plastic cap. I have fairly thin hair, so I was able to use just 1/2 a container. I rinsed the dye out thoroughly with warm water but did not immediately shampoo it out. I waited until it was totally dry before going to bed. This made sure the dye did not bleed onto the pillow. I didn't shampoo it until about 3 days later, and I always used a shampoo without sulfates. In each case, the dye faded somewhat but at 4 weeks it still looked pretty good. I then dyed it again. I am very happy with the results. I hope that if you try it this way, you will be happy with the results, too.

C'est nickel, on connais bien la marque, ça fait des belle couleurs pour les cheveux et qui tiens dans le temps, du Manic Panic tous simplement.

Me encanta el tono, si sigues las instrucciones del envase el color queda muy bien y es bastante duradero, yo tengo decoloradas solo las puntas y el frasco pequeño me alcanzó para tres retoques

I bought this color and after the first wash it looked quite dark and also stained my whole bathtub for a week or so, but with time it faded and then turned slightly greenish... after 2 months it still wasn't gone. I have a very warm skin tone so this wasn't very flattering to me personally. 3 bleaches later the ends of my hair are still blue... ill just have to cut it off it is what it is. the color looked very nice though for the majority of the time. still recommend it though to people who are dedicated to blue hair and love having it forever.
