Hi guys, I've had a rainbow for about 8 months now and I do it all with directions, but the staying power isn't great and some of the colours look very dull very quickly, even though they're lovely to begin with.
I do all the standard things for making the colour last longer, but it just goes dull fairly fast. The worst colours are the bright pinks and greens(spring green, flamingo, carnation pink). Are any of the other brands better for staying really bright? (I want it as bright as possible!)
For me, SFX has always started out bright and faded even brighter, if that makes sense.
I agree, sfx has brilliant staying power.
I agree about SFX, particularly atomic pink which is almost irreversible!
