Aquage Sea Extend Silkening Shampoo is a gentle, luxurious shampoo that prevents haircolor fade and thermal styling damage. Dual color protection that restores hair to its ultimate condition and protects hair against thermal styling damage. SeaExtend formula seals color in - an intensive blend of sea botanicals seals the cuticle and locks in color molecules preventing "wash out" to maintain longer haircolor results. SeaExtend Thermal-V Technology seals heat out - a sea-derived, enzymatic complex attaches deep within the hair shaft forming a heat-activated shield to prevent thermal styling damage.
