Shu Uemura Izumi Tonic Thickening Serum

Shu Uemura Izumi Tonic Thickening Serum is a leave-in treatment inspired by the Japanese tradition of rice water beauty rituals. Formulated to strengthen and thicken hair fibers, this serum boosts volume while reducing breakage. Its lightweight texture adds softness and smoothness without weighing hair down. Ideal for fine or weakened hair, it improves hair density and leaves strands feeling stronger, fuller, and more resilient.

Directions
Apply 2–4 pumps to towel-dried hair. Distribute evenly through mid-lengths and ends. Do not rinse. Style as usual.
