Manic Panic is WAY better than Splat since it doesn't bleed in the shower half as much. I swear I dyed my hair blue with Splat and a week later I had a blueberry colored bathtub. Manic Panic does bleed and fade but not as bad and not as fast. As far as I know it only comes in that gel-like form. I would suggest bleaching your hair at least a little because you'll get a weird effect if you have dark hair... even with the darker dye colors. Don't get it form Hot Topic though. THose are always sitting there for way longer and they curdle and harden and don't have as good of quality (I dont care what the bottle says about being able to keep it stored for a long time) Get it from a pharmacy or a beauty supply store like Sally's. They restock quicker and you're more likely to get a batch that hasn't been sitting there collecting dust and congealing.
I've used this before, and I have dark brown hair. FYI I was using purple.
It didn't last too long - about two or three months, although it was during the summer and I had to wash my hair a lot so that probably had an impact on the time. My hair stylist tells me that the dye will last a lot longer if you wash your hair with cold water if you can stand that.
The color was very nice, though. Despite being a weird color it looked pretty smooth, unlike a lot of at-home color products I've seen.
I don't think Manic Panic is available in my country, but I use Fudge Paintbox with excellent results (it's my first time using a bright dye, so I don't know how long it will stay blue). I bleached it before adding the colour. And it might not last in your hair, as it depends on the condition of it. I've been told that washing in cool water is a good idea to stop colour from running.
The dye I used was really easy to use, more so than any other hair dye I've ever used. Good luck!
It's different for each person. The only way to know is to try it. Those dyes are really picky.
If you don't bleach/dye your hair, it's probably going to last 1-3 months, probably on the lower side if your hair is dark (it may not all wash out, but it will fade to the point you can't see it).
Same goes for what works for you. It depends on your natural hair and how much processing you do on it. For me, Manic Panic doesn't last very long and washes out unevenly every time I've tried it. Splat color fades really fast and never fades out completely, I use it for pink and nothing else. Kool Aid works fine in my hair, too, though the color is harder to keep even and it also never fully washes out.
Special FX has almost always worked really well, and I prefer that brand. I only had trouble with the dye one time, and it was a color I'd used before and since, apparently there was an issue with that particular batch.
I'm using Directions, but I was told that it's the same as Manic Panic and yes, it's a gel. But if you have dark hair you should bleach them before using the hair dye or you won't see a lot of change. Also the colours stay longer on bleached hair. I normally dye my hair one or twice a week, it depends on the colour.
I heard a story like that too, so I didn't dye all of my hair. The worst thing that could happen is that I get pretty short bangs. But I'm dyeing them for over a year now and have probably bleached them 4 or 5 times and never got any problems. Sure my hair gets strawy after bleaching it, but with a good conditioner it's no problem.
Ah, I guess that would somewhat stop the effects. My hair was okay for about two years, but after that it was just dry no matter how much conditioner I used; I dye much less frequently now and it stays in good condition
If you don't bleach it, it's just going to look like you tinted your hair a little. The only way it gets a good color is if you bleach it since you have a dark base. As to whether it was a gel or a liquid or whatever, I don't remember, it was a while ago.
My advice, if you don't bleach it first, don't bother.
Unless it's black dye, good luck getting it to change colour at all, much less with semi-permanent! If you want it to be red, you really need to bleach it. Red fades incredibly quickly at the best of times; even with permanent dye dark brown hair will only get a reddish tint in sunlight.
For almost every colour, anything darker than a lightish brown will need bleaching if you want a strong result. Medium browns will only get tinted (unless you're dyeing it a very dark colour, but even then purples and such can lose vibrancy). Dark browns you pretty much have to bleach.
As for the product - I'm not familiar with it as I only use permanent, but go on websites that sell it and look at reviews for it. You are (slightly) more likely to get reliable results there rather than here.
