Hair breakage is a frequent consumer concern and is influenced by the condition and alignment of the hair, friction, tangle formation, and fibre knotting. A common way in the cosmetic industry to evaluate hair breakage is to subject hair tresses to repeated cycles of combing and evaluate the number of broken fibres.
The Bossa Nova Vision Sirtaki is an automated repeated combing system with fibre counting software, making it ideal to substantiate anti-breakage, less-breakage, resistance to breakage, and combing resilience1 claims for hair treatments. This test is ideal for treatments that lubricate the surface of the hair, such as conditioners, masks, and serums. A typical study would compare the performance of a product treated group of tresses to a control or untreated group.
