Review (5/5): The best dye for purple-blue tones.
I wanted a deep lavender with blue undertones, that would fade bluish rather than pink. I've used Special Effects on my daughter's dark blonde (unbleached) hair with great results, but was looking for more staying power this time, so I bleached my fine medium brown hair to a pale lemon.
I achieved this color by mixing equal amounts of Blue Mayhem and Pimpin Purple and then diluting the mixture with conditioner. I wrapped my head in saran wrap and a towel for about an hour, but unwrapped it halfway through to massage the mixture and redistribute the dye.
My hair felt really damaged after bleaching and sucked up the dye scary fast, but after rinsing and deep conditioning it felt soft and healthy again. I'll probably do a weekly deep condition with some dye mixed in to extend the life of the color.
