American Crew Classic Precision Blend Developer 4 5% / 15 Vol. 500ml

Mix your color exactly as you intend with the American Crew Classic Precision Blend Developer. The 15 volume (5%) formula lifts minimally while fully activating your favorite tints and glosses.

You get smooth, even application from the first squeeze to the last. The steady formula reacts predictably so your timing stays tight between clients.

The generous 500 ml bottle supports your daily schedule. These work perfectly when touching up root regrowth or mixing custom shades for seasonal highlights. You prepare less frequently while maintaining reliable potency across long shifts.

• Precise 15 Volume Strength Delivers controlled lift that updates existing color without pushing lighteners too far.
• Consistent Mixing Texture Stays uniform when folded into balms and liquids so your brush moves freely.
• Full 500 ml Capacity Cuts down on refill trips and keeps your tray well stocked for back-to-back appointments.

Apply it directly from your bowl to finish clean partings or lock in freshly blended tones before rinsing.
