Schwarzkopf Professional Bc Bonacure Ph 4.5 Color Freeze Shampoo 250ml

Stabilize fresh hair colour and protect the cuticle with a precision-formulated, pH 4.5 cleansing system engineered specifically for treated strands. The Schwarzkopf Professional BC Bonacure pH 4.5 Color Freeze Shampoo delivers targeted hydration and pigment lock-in mechanics that keep artificial tones vibrant while preventing unwanted oxidation.

Hair colour fades primarily because alkaline cleansers lift the cuticle, releasing dye molecules and exposing the cortex to environmental stress. This professional-grade formula counteracts that damage through a mildly acidic washing base that smoothly flattens the outer shield without harsh stripping agents. Gentle surfactant complexes remove scalp oil and styling residue while retaining necessary moisture to maintain elasticity and reduce mechanical breakage during post-service recovery.

Why stylists choose this formulation

• Precisely balanced at pH 4.5 to close cuticle layers and trap colour pigments inside the hair shaft.
• Formulated for all processed hair types, including vivid fashion shades, permanent dye, bleached lifts, and gloss treatments.
• Professional salon concentration delivers efficient lather and complete rinsability, making controlled dispensing straightforward in the compact 250ml container.
• Maintains scalp comfort during colour retention windows by reducing friction damage and mineral accumulation.

For clients managing frequent touch-ups or navigating tone transitions, sustaining an acidic wash environment is critical for preserving visual consistency. Apply a measured quantity to wet hair, emulsify at the scalp, distribute evenly through mid-lengths, and rinse thoroughly. Complete the regimen with a compatible acidic conditioning step to reinforce the sealed cuticle, lock in moisture, and maximize the lifespan of your colour appointment.
