Bigen Semi-Permanent Hair Color (R4 Intensive Red) is a professional-grade, high-performance direct-deposition pigmentation system engineered explicitly to deliver rich, vibrant color tones while optimizing structural defense parameters. Formulated as a gentle, cream-based coating, this advanced formula contains no harsh ammonia and requires no mixing with oxidative peroxide developers to process. It smoothly infuses individual hair strands to ensure comprehensive, high-clarity color coverage while maintaining the hair's natural moisture boundaries, leaving all natural hair textures exceptionally smooth, conditioned, and enhanced with a radiant, deeply saturated surface gloss.
