Kerastase Discipline Maskeratine Hair Mask, a deep smoothing treatment designed to restore control, softness, and fluid movement. This advanced formula is specifically developed for hair that is difficult to manage, helping to smooth the fiber while maintaining natural volume and flexibility. At the core of the formula is the Morpho-Keratin™ Complex, a combination of morpho-constituting agents and surface-morphing polymers that coat each hair fiber, restoring uniformity and creating a smooth, even surface. This helps reduce frizz, control flyaways, and improve overall hair discipline. The mask is also enriched with softening agents, which enhance suppleness and deliver an ultra-soft finish, and lipids, which play a key role in maintaining hair health by improving shine, strength, and manageability. Additionally, ingredients like amino acids and wheat protein help reinforce the hair structure, supporting smoother, stronger strands. This rich yet lightweight formula penetrates deeply into the hair fiber, offering long-lasting frizz control and humidity protection, making styling easier and more effective. With regular use, hair becomes smoother, softer, and more manageable, with improved movement and a polished finish.
