  • Worked Well
Color: Mermaid Size: 4 Fl Oz (Pack of 1)
Used this in combo with other colors for a “peacock” scheme. Great value!

  • Really enjoyed this.
Color: Mermaid Size: 4 Fl Oz (Pack of 1)
I used Ultraviolet and Mermaid for this ombre - both super easy to work with, blended beautifully, and were initially very saturated. I bleached and toned to white first and left it on (plastic-wrapped) for about four hours. Mermaid stayed bright a lot longer than Ultraviolet; both stained everything else they came in contact with. I needed most of the jar of each color - both sides are shaved, but what's left is very thick and coarse. I would buy Mermaid again but not Ultraviolet based on how quickly it faded - there's not enough in there for it to be worth it. ... show more

  • Nearly expired
Color: Mermaid Size: 4 Fl Oz (Pack of 1)
I'll say I don't care too much about expiration dates but I still thought it was shifty that I was shipped a dye that was within 1 month of its marked expiration.

  • Mermaid is a blue shade
Color: Mermaid Size: 4 Fl Oz (Pack of 1)
I was looking for a bluish green. I got Mermaid but it was more blue than green. I also am looking for a dye that will stick to my virgin unbleached gray hair. This dye worked better than all the other dyes I've used, but it was still pastel. It was more pigmented than Arctic Fox, Overtone, Keracolor, Colorista, and Punky Color. Update: Enchanted forest was essentially the same color, but more pigmented. I got a good blue iout of it. See comparison pic for the pigmentation difference. ... show more

  • Best at home hair dye since 90’s punk scene.
Color: Mermaid Size: 4 Fl Oz (Pack of 1)
We did light blonde first before the teal, picture makes it look darker than it actually is. Directions said, leave on for minimum of 30 minutes we did 45 minutes. I suggest for somebody looking to do more of the exact color shown for product you would need a bleached or very light blonde first. Side note- Not forgiving on skin, highly recommend applying product carefully, no one looks cute with a Blue forehead or ears. ... show more

  • Fantastic!
Color: Mermaid Size: 4 Fl Oz (Pack of 1)
I was a bit skeptical, because when I last used Manic Panic it was when I was in high school and it wasn’t super potent. This time I used it, I was SHOCKED. My hair is blonde (minus my shadowed roots) and the dye clung beautifully. It’s a BRIGHT green (think Sailor Neptune if you’re a weeb). I’m super happy with the result and will be purchasing again. ... show more

  • My very favorite, non damaging, vegan hair dye. Can't recommend it enough!
Color: Mermaid Size: 4 Fl Oz (Pack of 1)
I can not say how much I love Manic Panic. It is so nice to have a dye that is non damaging and vegan to use on your haoir and with so many cool colors you can use them separately or mix them for so many fantastic looks. I am a blond and it's usually hard to gef my hair to hold on to colors, but this lasts nearly a month, sometimes more and I simply can't recommend it enough! ... show more
