The Closer is a leave-in, two-in-one split-end sealing cream and light styling cream from amika, which the brand's own testing shows seals up to 96% of split ends per application. It works by coating and binding the split, frayed ends of the hair shaft closed rather than repairing the hair's internal structure — amika describes it as a sealant, not a cure, so it makes existing split ends less visible and less likely to travel further up the hair, not a way to reverse damage that has already happened.
The formula's main functional ingredients are amika's bond-fortifying complex (aimed at hydrogen bonds in the hair that break down from heat, chemical services, and everyday wear), sea buckthorn oil for lipid replenishment and shine, and vegan proteins derived from quinoa, rice, and baobab that mimic keratin's smoothing effect. It also contains dimethicone, a silicone that contributes to the smoothing and frizz control. The brand states the formula is vegan, cruelty-free, and free of parabens, sulfates, and phthalates, and that it is safe for color-treated hair.
It's positioned for all hair types and textures — straight, wavy, curly, and coily, fine through thick — applied to damp or dry mid-lengths and ends.
