Be mindful that with dying hair, if you're going for the silver/white that Dante sports, and you have dark or black hair, you'll have to bleach your hair in addition to dying it. Not entirely healthy for hair in the long run. And the fact that wigs look more authentic, you'll get a much better look for the rest of the costume. And you will avoid negative comments (because , people will blast you for not using a wig for Dante. I've seen it happen. Not pretty. >.< )
Yeah... Ragtime is much more on point with the whole hair situation. It's not that wigs look "more authentic". They don't, and it's often easy to tell when someone is wearing one by the quality, how it's worn, or if it's styled properly.
The problem I think you're talking about is the temporary dyes and sprays, like those you find around Halloween, and yes those generally look bad.
Before I start all this, know that Manic Panic Flash Lightning is not temporary
. It is bleach and bleach is permanent. There also isn't much product in those boxes, I'm bleaching my hair white for Dante as well and have used Flash Lightning before, so if you have longer or thicker hair you'll need several kits. It took 4 of the smaller ones for one round on my hair. But it will work... kinda.
Figuring out hair is actually very easy. To go darker you add color, this is dyeing your hair. To go lighter you must remove color, this is bleaching, there is no such thing as white hair dye.
. Anything that says it can dye
your hair white, is basically spray paint
and will most likely look like crap.
Getting white hair is not easy. It's a minimum two step process, probably more unless you're already a very light blonde. And it isn't good for your hair, you should pick up an overnight deep conditioning kit to use after you bleach your hair. Still you should expect your hair to be much more dry and brittle than normal.
Step one is the bleaching, step two is toning. What's nice about those kits is that they include toner, usually a very weak purple/blue tinted dye that has conditioner in it. After the initial toning you should have some left to use as refreshers for when you wash your hair. Don't use it every time however or you will end up with purple/blue tones in your hair.
Also, do not feel like you have to use these kits as they are rather weak from what I hear. 4 of them only go me to what I consider platinum blonde (think Malfoy from Harry Potter?) from a medium brown, so when I do the second round of bleaching, possibly this weekend, I'll simply buy a tub of cool toned bleach and some 40 volume activator as I still have several bottles of toner. If you only need toner, Manic Panic has a product called Virgin Snow that can usually be found with their dyes and is meant for countering brassiness and toning bleached hair to white.
You should also let your hair recover a bit between bleaching. If you're going to be doing this as a test before your convention, which I recommend because hair can be unpredictable and it may not turn out as light as you want it the first time, your hair will grow out showing roots which will need to be bleached again. I was recommended by my girlfriend's hair stylist to wait about two months or till you have 1/2" roots to bleach again.
Anyway... I'm no professional, this is just a collection of a few things that I've learned during my experience of trying to get white hair. Take it with a grain of salt as everyone's hair is different an you may, and most likely will, have a slightly different experience if you decide to go through with the process.
Remember that wigs are infinitely easier and can be reused. If you get a human hair wig, you can actually bleach it white just as you would your own hair, but those are expensive. Of course so are high quality artificial wigs for that matter... I had wanted white hair for a while anyway though, so I thought I'd give it a go. It's been an interesting experience.
