South Korea accounted for 42.9% of all hair loss cosmetic patents filed worldwide over the past two decades, the highest share among major economies, according to government data released on March 16.
The Korea Intellectual Property Office (KIPO) analyzed patent filings for hair loss cosmetics, including shampoos and ampoules, between 2002 and 2023. These products, designed to improve scalp health, enhance blood circulation, or regulate hormones, aim to prevent hair loss.
South Korea led with 576 patents, followed by Japan with 272 (20.2%), the United States with 231 (17.2%), China with 119 (8.9%), and Europe with 104 (7.7%). By ingredient type, South Korea dominated patents related to natural substances (50.0%) and bio-based materials (56.4%). The United States ranked first in synthetic compounds with 32.6%, while South Korea followed with 24.8%.
A South Korean pharmaceutical industry official noted that while hair loss is more common in Europe than in Asia, South Korea’s beauty-conscious culture and strong social stigma around hair loss have fueled local innovation. Many patents stem from ingredients inspired by traditional medical texts such as Donguibogam and Bencao Gangmu.
Among companies, South Korean biotech firm Caregen led with 115 patent filings, followed by cosmetics giant Amorepacific with 72. LG Household & Health Care ranked fourth with 25, making South Korea home to three of the top 10 filers.
“The hair loss cosmetics market presents a blue ocean opportunity where South Korea can establish a technological edge,” said Lim Young-hee, director at KIPO’s chemical and life sciences division.
