7SECONDS Detangler is a protein-based leave-in detangling spray from UNITE Hair, meant to be sprayed onto damp hair after shampooing and conditioning to smooth and detangle before you comb through. It's built around hydrolyzed rice protein and panthenol for light strengthening and shine, with a conditioning agent that helps seal the hair cuticle.
Beyond detangling, UNITE positions it as a leave-in thermal and UV protector, rated for protection up to roughly 450°F of styling heat, which makes it useful as a pre-blow-dry or pre-hot-tool step as well as a post-wash detangler. It's formulated as vegan, sulfate-free and paraben-free, and the brand markets it as suitable for all hair types, including chemically-treated hair and extensions.
You don't rinse it out — comb it through and style as usual afterward.
