Kosliv

Based in Shenzhen, China and founded in 2019, Kosliv (Shenzhen) Biotechnology Co. , Ltd. , trading under the name Kosliv, develops and sells scalp care products for consumers experiencing hair loss and premature graying. The company holds two invention patents issued by China's National Intellectual Property Administration for anti-hair loss and melanin promotion, and collaborates with the Harbin Institute of Technology (Shenzhen) on supramolecular penetration technology.

The founder is Ms. Han Juanjuan (Jennifer), a serial entrepreneur with over ten years of experience in cross-border beauty brand operations. In June 2026, the firm closed a series A funding round led by Tiantu Capital. The company provides to users a range of scalp care products including anti-hair loss shampoos, scalp serums, hair care essences, and hair oils, organized across five product lines targeting oily scalp, damaged or sensitive scalp, dandruff, flat hair, and dry or damaged hair.

The company also operates the brand Le Tan 1389, which provides standardized in store scalp care services through compact service cabins embedded in pharmacies, maternity stores, and office buildings, offering AI-powered scalp detection and serum infusion treatments. The company generates revenue from the sale of scalp care products through online channels including Tmall, Douyin and Xiaohongshu, as well as through offline lifestyle stores and scalp care institutions. The company plans to use the series A funding to invest in technology R&D, product upgrades, market expansion and team building.
