Iroiro 340 UV Reactive Blue Neon Vegan Cruelty-Free Semi-Permanent Hair Color

Got both green and blue, used them together and got a sort of peacock shade with some areas greener and some bluer. Great color with strong UV reaction. I've washed it twice now, and both the color and the UV are still strong, which is already better results than when I tried Manic Panic's UV line. Also, they have a blue UV, which is very hard to find in dye. So far very pleased. As a note, I did leave it in my hair for much longer than the instructions suggested (which is usually safe with semi-permanent shades like these), and everything turned out great.

I love the shades of iroiro so much, the ones I tried never let me down, the texture is great and it's amazing that it also gives the hair nourishment because of the ingredients used in the dye, the only slight disappointment for me is I've ordered the uv reactive blue and despite the package says it's uv reactive, it doesn't really glow under uv light for someone reason
