Hair Care Products Efficacy Evaluation

In daily life, factors such as perming, dyeing, using strong shampoos, exposure to high temperature, sunlight, and physical friction can severely damage hair’s cuticle and cortex, leading to dry, brittle and yellowed hair. To combat these issues, the cosmetic industry has developed a variety of hair care and scalp care products for consumers.

Then how to evaluate the efficacy of these products in improving the damaged hair? How can we know the actual effective of these products? CIRS Testing offers industry-leading hair testing services. These tests help companies assess the efficacy of their hair care and scalp care products, providing the scientific evidence for products’ efficacy claims and ensuring its competitiveness in the global market.
