Designed for people with thick, coarse, or dehydrated hair that tangles easily and doesn't hold moisture well through the day; works as a daily leave-in step for at-home routines and is also carried through professional salons. Not aimed at fine or oily hair, where a lighter leave-in would be more appropriate.

The main differentiator is the delivery method rather than any single ingredient: Joico's liposome-based SmartRelease system keeps releasing rosehip oil, arginine, and vegan keratin into the hair gradually rather than depositing everything on contact, which is the mechanism behind the "24-hour" moisture claim. Combined with Olive Ester standing in for silicone, aimed at smoothing and softness without a heavy silicone film.

Apply evenly through clean, damp hair, avoiding the root area so the scalp isn't weighed down. Style as desired. Leave in — do not rinse out.

Pros: the liposome delivery system is a genuine mechanism for slow-releasing rosehip oil and arginine rather than ingredients that just sit on the label; substituting a vegan protein source for animal keratin is a real formulation choice; works well as a detangling step ahead of styling on coarse hair. Cons: applying too close to the roots can weigh down fine or thin hair, hence the instructions to avoid the root area; as a leave-in it doesn't cleanse or deep-condition on its own; the "24-hour" claim is based on the brand's own testing rather than independent verification.
