Collaborative research on a hair heated damage model, jointly conducted by Hangzhou C&K Testing Technic Co., Ltd. (CIRS Testing) and Amway (Shanghai) Innovation and Science Co., Ltd. (Amway), has achieved significant progress. The findings have been formally published in the internationally authoritative SCI-indexed journal- Journal of Cosmetic Dermatology. This breakthrough study not only provides a novel scientific tool for in-depth exploration of hair heat damage mechanisms but also marks a new level of global recognition for China’s cosmetic efficacy evaluation technology within the international academic community.

​As a leading third-party testing institution in China, CIRS Testing maintains focusing on the R&D for cosmetics and personal care products and has possessed extensive technical expertise in cosmetic efficacy evaluation, especially in hair product efficacy evaluation. Amway, as a globally recognized company in health and consumer goods, prioritizes developing safe and effective personal care solutions with an ongoing commitment in hair care products innovation. Based on the shared commitments of scientific research and technological developments, the two companies jointly established the collaboration in the development and application of heat-damaged model for hair.

This model has introduced three core technological innovations, including:

1. The construction of reproducible and quantifiable simulation methods, to precisely replicates hair damage status in real-life usage scenarios

2. The pioneering microscopic imaging technology for observing hair cuticle conditions in longitudinal hair cross sections will visually show the damaging details and the repairing efficacy of products. Compared to the traditional method, this technology will provide a comprehensive analysis of the hair surface structural changes and offers a novel microscopic perspective for damage mechanism research and product efficacy evaluation

3. Groundbreaking application of micro-level infrared spectroscopy enables precise analysis of hair moisture distribution patterns.

In addition, in the field of hair efficacy evaluation, CIRS Testing has developed six comprehensive damage scenario models (covering heat, chemical, physical, air pollution, UV exposure, and seawater/pool water damage). By integrating three key analytical dimensions—physical performance, chemical composition, and microscopic imaging, CIRS has established a comprehensive framework for in-vitro hair efficacy evaluation, to quantitatively assess the hair damage scenarios and provide scientific support to clients from product development to marketing communication.

As a National High-Tech Enterprise, CIRS Testing consistently upholds its mission of advancing industry progress through technological innovation. Leveraging its sound laboratory construction, expert teams and extensive experience, CIRS Testing has delivered one-stop solutions to various renowned cosmetics brands. Currently, CIRS Testing holds over 20 patents and has participated in the drafting of 4 national standards and over 20 industry group standards. Moving forward, CIRS Testing will continue to uphold its service philosophy and make contributions to the development of cosmetic industry.
