Transform your hair overnight. MEDULLA presents HYPERLINK SERUM, the most advanced damage care leave-in hair serum in MEDULLA's history. 1. A unique formula containing a low-molecular-weight peptide, a first in Japan. The key ingredient in this product, peptide, was developed in collaboration with domestic and international experts in the development of functional ingredients. These ingredients were then commercialized through joint development by Storia Co., Ltd. and Sparty Co., Ltd. A fusion of hair science and botanical research has resulted in the formulation of a biomimetic ingredient with a structure similar to hair keratin. It repairs hair three-dimensionally at a deep level. 2. Low-molecular-weight peptides that allow penetration deep into the hair. Penetrates deep into the hair to repair damage.
