The K18 Client Mask Pack contains five individual 5 ml applications of a professional hair treatment mask designed to restore hair health and vitality. This intensive care formulation works to repair damaged hair structure at the molecular level, addressing common concerns such as breakage, split ends, and reduced elasticity. Each 5 ml sachet provides sufficient product for one complete treatment session, making this five-pack ideal for regular maintenance or sharing among household members. The mask's advanced peptide technology penetrates deep into the hair shaft to rebuild broken bonds and reinforce the hair's natural strength. Suitable for all hair types including color-treated, chemically processed, and heat-damaged hair, this treatment requires no additional steps or heat activation for optimal results. Simply apply to clean, towel-dried hair, leave for four minutes, then style as usual without rinsing. The concentrated formula ensures efficient delivery of active ingredients while minimizing product waste. Clinical testing demonstrates measurable improvements in hair smoothness, shine, and manageability after consistent use. The compact 5 ml packaging maintains product freshness and potency while providing precise dosage control. This professional-grade treatment is formulated without sulfates, parabens, or silicones, focusing on pure, effective hair restoration. Users report noticeable reduction in frizz and increased hair resilience within the first few applications. The mask's lightweight texture absorbs quickly without leaving residue or weighing hair down. Regular use as part of a comprehensive hair care routine helps maintain optimal hair condition and prevent future damage from environmental stressors and styling tools.
