Schwarzkopf Professional Bc Bonacure Ph 4.5 Color Freeze Shampoo 1000ml

The Schwarzkopf bc Bonacure pH 4.5 Color Freeze Shampoo is a 1000ml professional-size cleanser engineered to lock artificial pigments into the hair shaft while maintaining an acidic balance that inhibits premature fading.

Most conventional shampoos operate at alkaline levels that force the cuticle open, allowing dye molecules to wash out after just a few cycles. This formula stays calibrated at pH 4.5, keeping the outer layer sealed and shielding treated fibers from oxidation, heat styling stress, and mineral deposits found in standard tap water. The result is consistently preserved tonal integrity for blonde, red, brown, and fashion shades without stripping the underlying base during cleansing.

Supplied in a 1-liter vessel, this product matches backbar standards for salon use, providing accurate dispense measurements for multiple client treatments. At home, a small quantity lathers efficiently to remove sebum, product residue, and environmental grime while leaving processed hair soft and manageable. Use two to three times weekly as part of a targeted routine that alternates with deep conditioning masks. Suitable for chemically relaxed, permed, and freshly coated strands when paired with compatible leave-in sealants.
