Damaged hair is about to meet its match.

Damaged hair is about to meet its match. With Tokyo as the brand’s origin and inspiration, Shu Uemura Art of Hair intertwines Japanese precision with modern luxury hair care. The brand is expanding its best-selling Ultimate Reset franchise with the NEW Ultimate Reset Extreme Repair Leave-In Mask, launching September 15, that’s built to repair, protect, and strengthen hair without sacrificing that weightless, bouncy movement.

The Technology Behind It 

The formula’s standout feature is its Hydro-Oil Transfusion technology — it starts as a milky cream and, upon emulsification, transforms into a lightweight oil. That shift allows reparative ingredients to penetrate deep into the hair fiber while leaving zero residue behind.

The Formula

At the core of the leave-in is Japanese Hyogo rice, prized for its nourishing and restorative properties. The multitasking treatment delivers amplified repair while helping prevent future damage — and the results show up fast. In just one use, hair is left visibly stronger, smoother, and shinier, with up to 99% less breakage* and heat protection up to 450°F.

The mask works two ways: apply to damp hair before styling for repair and thermal protection, or smooth over dry lengths between washes for added nourishment and shine on no-wash days.

As consumers gravitate toward hardworking products that simplify their routines without cutting corners on performance, the Ultimate Reset Extreme Repair Leave-In Mask delivers salon-level repair in a lightweight, sensory formula — protecting, strengthening, and restoring hair with every use.

The Ultimate Reset Extreme Repair Leave-In Mask retails for $68.00 and launches September 15th on shuuemuraartofhair-usa.com, sephora.com, and amazon.com. You’re gonna want to get your hands on this one!
