🌈 Dare to Glow: Neon Hair That Commands Attention
MANIC PANIC Classic Siren's Song is a semi-permanent neon blue-green hair dye designed to last 4-6 weeks. Vegan, cruelty-free, and free from harsh chemicals, it delivers vibrant color that glows under blacklight. Best results come from application on pre-lightened hair, allowing for bold, customizable shades that fade gracefully without damaging the hair shaft.

Love that they’re cruelty free, but just didn’t stick.
I’ve used Manic Panic several times before, but for some reason this time around I had issues with the color coming out after not even a week. I had bleached my hair as light as it would go prior and it still washed out. I had to reapply twice.
