Deadly nightshade
I love that your product is not full of weird stuff but I've had it on a week or two and it's already very faded. I haven't even washed it yet. It's faded to a good color but I left it on all day and it shouldn't be fading already. Anyway, I love you guys and thank you for starting the revolution

Deadly Night Shade Excellent! The color is so vivid and sticks to my hair better than other colors. It is also a sentimental favorite as My kiddo wore it for years back in the day when we first found it at Hot Topic. . . . now the Oops. . . Packing, shipping, we had an open container Jars went in the box, then the paper stuffed in, but only on one end, of the box. so the jars did not do so well during shipping. one was knocked around a little tooo much and arrived with a spill. Messy, but no actual damage to the 4 jars purchased, just inconvenient. Got my purple back. Still would not purchase any other product, Love my Manic Panic Deadly Night Shade

Love this hair dye but one out of three wasn't closed tight enough and leaked inside the box.
