K18 HeatBounce Conditioning Heat Protectant 118ml uses Resilicore™ Heat-Shielding Technology to protect up to 232ºC while conditioning, detangling, and reducing breakage after blow-drying.
K18 HeatBounce Conditioning Heat Protectant 118ml is a leave-in formula that protects hair from heat up to 232ºC while reducing breakage after blow-drying. This lightweight conditioning spray combines heat protection with daily care. First, it detangles and softens the hair, making styling easier. At the same time, it helps reduce friction during brushing and blow-drying. As a result, hair feels smoother and more manageable, even when damaged. At the core of the formula is Resilicore™ Heat-Shielding Technology. Inspired by proteins found in nature that withstand extreme temperatures, this technology goes beyond surface-level protection. Unlike traditional heat protectants that coat the cuticle, Resilicore™ features a specific size and molecular structure that allows it to penetrate deeper into the hair’s inner cortex. Therefore, it helps shield areas where heat damage can occur and fortifies the hair from within.
In addition, the conditioning blend enhances softness and improves detangling without weighing the hair down. Although the texture feels lightweight, it supports protection during blow-drying and other heat styling steps. Over time, consistent use contributes to visibly less breakage, with up to 85% less breakage after blow-drying. This formula suits all hair types and textures. Furthermore, it can be used on extensions, making it a versatile option for different styling routines.
