Achieve salon-quality results with the POWERTOOLS Gray Coverage & Resistant Hair Kit, a professional three-piece system featuring G.O.D Gray Oxidizing Drops, TRA The Resistant Assistant, and TCA The Color Accelerator. Together, these advanced additives maximize gray coverage, speed up processing, and enhance shine. G.O.D improves oxidation and allows deeper pigment penetration for stronger, more even coverage on resistant gray hair, while TRA softens the cuticle in stubborn areas like the hairline and temples to ensure color applies evenly from root to tip. TCA reduces processing time while locking in moisture, vibrancy, and long-lasting brilliance. Compatible with all manufacturers’ hair color, bleach, and lighteners—whether semi, demi, permanent, or hi-lift—this universal system is trusted by salon professionals worldwide to overcome resistant textures, stubborn gray regrowth, and time-sensitive services. Designed for consistent, professional-grade results, the POWERTOOLS additive trio transforms the coloring process with improved efficiency, superior coverage, and lasting shine.
