Hair Removal Effect

This test determines the effectiveness of a hair removal product.

The test is performed by capturing high-resolution images of the treated area before and after the application of the product. The test is typically performed on a small area of skin, such as the hands or legs. The images are then analyzed by a trained technician to manually count the number of hair roots remaining after treatment. The reduction in the number of hair roots indicates the efficacy of the hair removal product.
