Flash Lightning 40 Volume Complete Maximum Hair Lightening Kit : Best box bleach but...

The 40 Vol Manic Panic bleach is the best box lightener I've used for my hair. I have very dark brown, almost black, hair, and a lot of bleaches - especially with vol 20 developers - don't lift me more than maybe 2 or 3 shades, and I get stuck in the wonderful red/orange phase. THIS however gets me from my natural to a nice light blonde (so from about level 3 to level 10) in one sitting!

The only issue I've come across, is with my last 2 purchases, as the developer in both have had foam coming out of the closed bottles? Now, my hair is highly stubborn, the developer still mixed with the powder well, and my hair didn't seem to be anymore damaged that it normally is after a bleaching. SO I'm not sure if the developer was expired or not? There's no dates anywhere on either boxes, so I have no way of knowing. But, again, it still bleached my hair and didn't make my hair fall out or anything, which is why the foam only takes off 1 star.
