Manic Panic Formula 40 Knight Bright Purple Semi-Permanent Hair Dye Hot Topic Exclusive is rated 4.7 out of 5 by 33.
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!

Rated 5 out of 5 by from Looks good even on brown hair! I bought this dye specifically in hopes of it looking good not just in my blonde highlights, but also my natural hair color. I am a brunette, light brown. It's been three weeks since I've dyed my hair, and the color is still very powerful in my blonde parts, and it shows on my brown hair. I've washed it about 4-6 times. I'm pleasantly surprised by this product, and I would buy again! Please make more colors with this formula!!

Rated 4 out of 5 by from Great color! This is the second time I’ve used this exact dye and I love it. The color is beautiful, and I love that’s it cruelty free and vegan. The only complaint is that I wish it lasted a little longer, but I can put up with fading because it’s such a minor complaint in comparison to all the positives.

Rated 4 out of 5 by from Perfect color! I had been looking for a good purple like this. It's easy to apply. I get better coverage from this than I have with creme colors.
