Stella Seed launches new 8 THE THALASSO serum hair oil

Stella Seed Co., Ltd. has announced the launch of a new serum hair oil as part of its ‘8 THE THALASSO’ Silky & Refine series. The product features a ‘Thalasso Silky Formula’ containing over 99% beauty essence, utilizing uniquely developed ultra-high pressure treated silk to address hair issues such as frizz, dryness, and stiffness.
