Review (2/5): Like a Tattoo
I bought Splat Blue Envy about 6 months ago. I had my friend put it on that night (we've both used Splat before and have never had problems), but this time I used the packaged bleach first (I had never bleached before dyeing). I have naturally reddish-brown hair and I dyed the underside of my hair. Looked super super awesome for about a week and a half. It started to fade into a really ugly greenish-gray color, so I really had to stay on top of doing touch ups every week. I got tired of that and decided I wanted to do a different color. I tried Manic Panic purple haze to do a cover up without bleach, my hair was still bright blue and faded to the same gross color. So then I bought Manic Panic Hot Hot Pink and Raven, to do a pink and black layer on my underside. We rebleached my hair... And my hair was still blue! We dyed over it with the pink and black, the pink came out purple and the black came out a dark blue. It's been 5 months since I last used Splat and I STILL cannot get it to leave my hair. I've tried multiple home remedies, Color Oops, etc.
In conclusion, don't buy or use Splat unless you plan on having the color for a long long time. I assume this will go for all the Splat colors as well.
