Hair Friction Combiner Material Testing Machine

Product features of hair friction, stretching, softness, and bending resistance combing machine
The Shanghai Xiangjie XJSL multifunctional hair combing device can test the friction, stretchability, flexibility, bending resistance and other characteristics of hair. After testing, the improvement effect of hair care products on hair quality can be evaluated. By measuring the combing resistance of products such as shampoo, hair dye, and conditioner, the required total workload and resistance for combing can be obtained, and the effectiveness of the care product can be determined.
Application Domain
Test the mechanical and physical properties of hair, evaluate the efficacy of hair products, and select suitable product formulas.

operating procedure

1. Hair friction

During the hair friction test, the friction roller is tested in the direction from the root to the tip, and then in the opposite direction from the tip to the root. The frictional force from the hair tip to the hair root direction is greater than the frictional force from the hair root to the hair tip direction, which is caused by the branching of hair scales.

2. Stretchability

Hair stretch testing is a common test conducted by various hair product manufacturers. When we use a combing machine for testing, we can use one hair or multiple hair. When testing multiple hairs, we recommend preparing the sample by sticking different hairs together. Adhesives, wax, or other materials can be used to prepare the sample. Examples are shampoos, hair dyes, and gel. Testing the strength of hair is very important in order to determine whether these hair products enhance or weaken the strength of the hair. The selection of fixtures is crucial during hair stretching testing, as there should be no slipping, pinching, or other issues.

3. Flexibility

When taking care of hair, there are various products such as hair conditioners and essential oils used for hair softness testing. We need to choose according to our own needs. If we want our hair to be smoother, we need to do a hair care essential oil softening test before purchasing the product.

4. Bending resistance

When evaluating the effectiveness of bending retention in hair bending resistance testing, circular hair bundles are used. This is because circular hair bundles can better restore the state of hair when using styling products, making the evaluation results closer to the actual use effect. Bending retention efficacy evaluation is a cosmetic efficacy testing method that evaluates the styling effect of a product by comparing the length changes of hair strands with and without test samples at different time points. This method is suitable for the durability of hair styling products such as gel, mousse, hair gel, hair wax, and elastin.

The bending test can test the rigidity of hair. The flatter the cyclic curve, the better the elasticity and rigidity of the hair. The rounder and wider the cyclic curve, the poorer the elasticity and rigidity of the hair. The elastic modulus E in the test results represents the stiffness of this bundle of hair. The higher the E value, the greater the stiffness and the less likely it is to deform.
