Review (5/5): Really great product, just be aware of how permanent it is
I love this stuff! It's great for long lasting pink hair. Since I love pink and rarely change my hair color I am in love with this product - however, be warned that this is REALLY hard to get out if you need to change your hair. When going from all pink hair to a blonde pink gradient, I tried color stripper, clear dye, and even bleach and the pink would not budge, just become even more vibrant. I had to go to a salon to get it out.
But I love it a lot because I can wash my hair daily and the color fades very slowly. I recommend it, just be careful!
