Aekyung Industrial presented new research on L-Tetrahydropalmatine (L-THP), a phytochemical from Corydalis yanhusuo, at the 14th World Congress for Hair Research (WCHR) in Seoul. The study demonstrates L-THP's potential as a novel functional ingredient for hair loss alleviation, offering overseas buyers a scientifically backed, natural-origin option for premium hair care formulations.
Research findings
The study, titled 'A Study on the Hair Loss-Alleviating Effects of L-Tetrahydropalmatine,' showed that L-THP promotes proliferation of human dermal papilla cells and outer root sheath cells. It also induced expression of hair growth factors VSCN, ALP, and VEGF. In human hair follicle tests, L-THP stimulated hair growth and inhibited follicle regression, confirming its potential as a new functional ingredient for hair loss mitigation.
Regulatory and channel signals
Aekyung Industrial has secured patents for L-THP and completed ICID (International Nomenclature of Cosmetic Ingredients) listing. The company recently confirmed efficacy in human application tests and is preparing to obtain non-notified functional raw material approval from Korea's Ministry of Food and Drug Safety under the ingredient name 'Tetrahydropalmatine.' This regulatory pathway signals readiness for commercial use in cosmetic products.

Sourcing context
The global hair care market is increasingly embracing 'skinification'—treating the scalp like facial skin—driving demand for high-efficacy ingredients. Aekyung plans to apply L-THP in premium shampoos and tonics, targeting both domestic and international markets. For overseas buyers, this presents an opportunity to source a clinically validated, naturally derived active ingredient aligned with the skinification trend.
What buyers should watch
Importers and distributors should monitor Aekyung's progress toward MFDS approval and potential finished product launches. The ingredient's dual mechanism—cell proliferation and growth factor induction—positions it as a versatile addition to anti-hair loss lines. Early engagement with Aekyung could secure first-mover access to this novel active for private-label or branded formulations.
