HAIR VOLUME TEST

Hair volume testing refers to a series of assessments used to measure the fullness or thickness of hair. These tests can be utilized to evaluate the effectiveness of hair care products, assess hair thinning or loss, or compare the characteristics of different hair types.

Several methods are commonly used to measure hair volume, including:

1. Hair Bundle Measurement

In this method, a small bundle of hair is collected, and its diameter is measured using a micrometer. This provides insights into individual hair strand thickness and hair density on the scalp.

2. Phototrichogram

This technique involves capturing high-resolution images of the hair, which are then analyzed using specialized software to determine the number, thickness, and growth angle of hair strands. It offers a comprehensive overview of overall hair volume.

3. Laser Scanning Microscopy

A laser is used to create a three-dimensional image of the hair, allowing for detailed analysis of strand diameter, shape, and arrangement. This method provides in-depth structural and volumetric information about the hair.

4. Subjective Evaluation

Trained experts visually and tactically assess hair fullness and thickness, scoring it based on a standardized scale. This method can be used to validate other test results or provide a general volume assessment.

The Importance of Hair Volume Testing

Hair volume testing serves as a valuable tool for both researchers and hair care professionals. Researchers use these tests to develop and evaluate new hair care products, while hair care specialists utilize them to provide personalized recommendations and track the effectiveness of treatments.
