Siren's Song™ - Classic High Voltage

Siren's Song™ delivers a mesmerizing neon blue-green hue that demands pre-lightened hair for maximum vibrancy. For best results, apply to hair that has been pre-lightened to level 10 blonde. This ensures the pigment deposits evenly and achieves the full intensity of the Classic High Voltage formula. Perfect for those seeking a bold, statement-making color that turns heads.
