Review: Vibrant. Recommend the brand and this color! Blue/aqua, colors are EXACTLY as chart shows! ( - Everyone who’s ever died there hair at home before a vibrant color at least, knows the brand manic panic. You can’t compare other hair dies to them, simply put. There the best out there. Huge array of colors to choose from, colors are vibrant and beautiful. Best of all is the longevity of the die. I’ve always used manic panic colors for this reason, I’d rather bleach and die my hair once every 5-6 months vs every 2-3 with other brands. And touching up is so easy and simple, especially because there is so much product in each jar. I bought this and died half my hair and have at least 2/3rd’s of the jar still left. I plan to touch up my roots next week and I’ll still have 1/2 the bottle left for whenever I want to redye over it, and I won’t have to bleach again simply put it right on top. Look up this brands reputation, you’ll purchase the product after. Love, love, love this color !!! It’s to dye for :) to all those who got that... seriously if your looking for a nice teal/green color this is it! It’s lighter blue with a hint of aqua - (check the chart on there website you’ll see the EXACT colors) that’s also the best about them, what you see is what you get. The color they show is the exact color your hair will be IF you do what they suggest. They show you if you don’t bleach the color it’ll be, if you have blond hair already the color it’ll turn out like, and if you bleach the color it’ll turn out like. I bleached my hair this time, and if you put my hair next to the swatch they show you it would be identical. Amazing product, lasts longer then any other, vibrant array of colors - huge array to choose from, well packages was still sealed tight with sticker tapes on the sides to show it’s never been opened before. Shiny vibrant amazing colors !
Review: Great colors for hair! - I have been buying this brand for such a long time. I just use it on my ends and it just give a flare of color. Easy to use and will fade with washing.

## Questions & Answers

**Q: my daughter wants lavender hair but i am thinking that the virgina snow or what ever would be too light what do i do and what color**
A: Virgin snow is not a purple dye. It is used to tone blonde hair white.If you want lavender, mix this with conditioner until the dye is the color you like. What you see is what you get. Its like paint.The color you get depends on how light her hair is. The lighter the hair, the more true to the purple itll be.Also, if you leave it on overnight, it might as well be permanent. Its been 3 months since i left some in for 11 hours, and it never came out. But half an hour will wash out right away. An hour or two will last a week or two.

**Q: Do i need to use Color developer with this or can i use it stright out of the container?**
A: Nothing else is needed to use this hair color. You can use it straight out of the jar.  The times you might want to consider adding anything to it is if you want really vibrant hair, then you will need to possibly bleach your hair if you don't have very light blonde or white hair.  The most the color will do is give you a nice tone of deep, rich red color to any hair color when used straight out of the container. Be sure you wear gloves, use old towels and wear old clothes when using color. It stains everything for weeks and the color is hard to remove from fabrics and surfaces.

**Q: If i used this on dark hair, would the color still show as blue...or must i bleach or lighten it?**
A: Dark or darker than a Hershey bar it will be a kind of highlight you see in the sunlight. If you want it to actually be blue and your hair is dark or darker than a Hershey bar I would get the lightener kit from Manic-Panic. I wouldn't use a different brand. To test what color you will end up with, put your hair in a pony tail and put about a dime-size of color on your hair at the back of your head under the pony tail. Wait 30 min. rinse (maybe blow dry) and see for yourself if it is the color you were hoping for. *I wash (not condition) before I use and with the 3o min. it takes to soak into and stain the hair it takes me about 1 1/2 hours to wash, dye and clean up. Don't forget gloves, plastic bag that is big enough to put your wet head into and a plastic tie (or showercap) and a couple rags. I use petrolium jelly as a barrier to keep most of the Dye off my skin "dye-free". The color will transfer to your hands and nails in the shower as you rinse it off. I use three seperate pairs of gloves #1 to apply petrolium, #2 to apply dye and #3 to rinse. Then condition as is normal for you. If you do not have brittle hair, it is safe to "wear" overnight. Just leave the plastic(or showercap) on your head and cover the whole thing with a black knitted cap. Shampoos/conditioners that are for colored treated hair work better than the regular kind for adding days or even a week to your color. Ecxess dye can be removed by bleach or diluted bleach. If the dye gets on fabric, it will stay dyed. If you want less clean up go to the 99cent store and buy a new shower curtain. Good luck!

**Q: Will it show on brown hair and will it bleed? How long does it last**
A: It will show somewhat I cover and leave it on my hair 30 to 60 minutes it may bleed a little. You can use it often without any damage to your hair. Good luck! It depends on have often you shampoo how long it lasts I shampoo once a week as I wear a short pixie with no excess oil to hair or scalp.
