This test measures the effectiveness of a product in reducing hair fall. This is done by a combing method, where the number of fallen hair is counted before and after product application. This allows the evaluation of the efficacy of a product in reducing hair loss, breakage, and shedding.
The test involves combing the hair with a standardized comb for a specific number of strokes before and after product application. The hairs collected from the comb are counted to determine the percentage reduction in hair fall. The test can be performed on both wet and dry hair, depending on the product's instructions.
This method is a reliable and objective way to assess the effectiveness of a hair fall reduction product. The test results can be used to demonstrate the efficacy of the product and can help beauty companies in developing effective anti-hairfall products.
