A semi-permanent blue gel hair dye kit designed for bold DIY color has arrived from outer space. Inter-GEL-actic™ delivers intense pigment, visible control, and ultra-glossy shine in a vegan, cruelty-free formula. Each complete, DIY-friendly kit includes two 2 oz tubes for all-over color, streaks, or saving one for later, because the universe isn’t just out there, it’s in your hair.

Celestine Blue™ is a deep space blue with cool undertones and a celestial finish. Saturated and long-lasting, it creates bold dark blue results on light blonde or pre-lightened hair and deepens into dimensional navy blue tones on unbleached medium or dark hair.
