Cosmax Files Patent for AI Model Predicting Alopecia Areata Risk
The Korean cosmetics manufacturer is expanding its personalized hair-care business with an AI risk model, global scalp research and new materials for damaged hair.
South Korean cosmetics manufacturer Cosmax has filed a patent application for an artificial intelligence model designed to predict the risk of alopecia areata, stepping up its push into personalized hair care and data-driven product development.
The model was trained on about 22 million health-screening records from South Korea and Japan, according to the company. It evaluates 33 physiological and medical variables without requiring users to provide additional biological samples. Cosmax has tested the technology through Byniq, its personalized beauty platform, which uses questionnaire responses to recommend products for hair-loss care.
The project is part of a broader effort by the cosmetics original design manufacturer to combine artificial intelligence, large-scale health data and research on differences among consumers. Cosmax said a separate study of scalp lipid profiles from 387 participants of East Asian, European and African backgrounds identified three scalp types as well as vulnerabilities that varied by ethnicity. The company plans to use those findings to develop biomarkers and products tailored to different groups.
Cosmax has also worked with Seoul National University to develop Corelink-S, a material intended to repair damaged hair by restoring cystine bonds. The company said the material improved the tensile strength of damaged hair by more than 120 percent. The claim reflects company testing and will be relevant as Cosmax seeks to translate laboratory research into products for global beauty brands.
Hair care is becoming a more significant business line for Cosmax. Its sales in the segment increased about 65 percent from a year earlier during the first half of 2026. The company also filed 37 hair-care-related patent applications over the past three years, indicating a sustained investment in the category rather than a single product initiative.
The expansion is extending beyond Korea. Cosmax is working with specialty ingredients company ScienceCo on a curly-hair line designed to address 12 hair and scalp conditions. In July, it established Trynex with Japanese beauty distributor Fujishin, pairing Cosmax’s AI-based formulation capabilities with local distribution expertise.
The latest patent filing places the individual company and its product strategy at the center of the story. While the technology relies on AI, its primary significance is commercial: Cosmax is building a portfolio of research, intellectual property and partnerships aimed at the growing personalized hair-care market.
