Review (5/5): Best dye ever!
I first got my pink done at a salon, and a week later it was gone. I've since learned a lot (like don't wash in hot water, don't wash every day, and don't use flat iron or heat on the color). I wanted to experiment with doing my own dye job since the salon is expensive. I also recently bleached my son's hair (which was dark brown) and because he wanted a variety of colors, we used the atomic pink but also bought a couple of the Ion (tm) colors at Sally's as well.
The Special Effects dye was hands down the easiest product to use. The other product was clumpy and a bit too creamy. SFX is thick enough that it doesn't run off the applicator brush but liquid enough that it easily saturates the hair. The color lasts much longer and remains true to color much longer as well (I did rinse in 1 part vinegar 1 part water before rinsing and conditioning).
I will buy this brand of dye and none other from now on!
