Manic Panic Formula 40 Knight Bright Purple Semi-Permanent Hair Dye Hot Topic Exclusive is rated 4.7 out of 5 by 37.
Rated 5 out of 5 by from Great hair dye!! i've struggled to find a good purple that lasts a long time. even permanent purples fade so quickly. this is the best purple hair dye i've used. it lasts longer than most permanent purple hair dyes. i bought this dye back in february and my hair is still purple! i mainly bought this dye because i'm a fan of the band waterparks and i wanted to try it out, but this is by far the best purple hair dye out there!

Rated 4 out of 5 by from Nice but not perfect I absolutely love the color, but it didnt cover my hair 100%. Some areas came out well colored while others that were just as covered in dye were lacking a bit. But overall i love the dye and will use it again

Rated 5 out of 5 by from My favorite. My friend dragged me a warped tour booth to get a shirt from her favorite band. Me being me, saw hair dye and the booth and snatched it up. I’ve always struggled to find long lasting purples (it’s even hard for my hair stylist) but this is the best purple I’ve ever had. It works so well and stay vibrant for so long. I just recently purchased my third bottle of this dye since June.

Rated 5 out of 5 by from Exactly as described This color is gorgeous and so vibrant. We took it to our hair stylist to lighten his hair and apply it. She put the cap on and he was under the dryer for about 20 mins, 30 mins total processing. A couple spots are a little lighter, but we think that’s due to how his hair lightened, not because of the product. Will definitely use again!
