Hair and Related Tissue Products — Anti-Hair Loss Efficacy Testing
Hair loss has become a widespread concern worldwide. From young professionals to middle-aged consumers, an increasing number of people are paying greater attention to scalp health and hair care management. At the same time, as anti-hair loss products continue to gain popularity, brands face a key challenge: how can their actual efficacy be scientifically validated? To answer this question, reliable clinical and experimental evaluation methods are essential.
Shampoo and Combing Test (Wash & Combing Test)
Applicable Claims: Reduction of hair loss; reduction of the number of shed hairs by X%.
The Wash & Combing Test evaluates changes in hair shedding during shampooing and combing before and after product use. The number of shed hairs is counted and compared to assess the product’s anti-hair loss efficacy. The evaluation includes both wet-combing and dry-combing methods:
(1) Wet Combing Test
This test is conducted during the shampooing process. The number of shed hairs is counted, with approximately 100 hairs generally collected for evaluation. Hair shaft breakage is not included in the count.
(2) Dry Combing Test
This test is performed during hair styling or daily combing. After a single application, at least 25 shed hairs are collected and counted. Hair shaft breakage is not included in the count.
TrichoScan® Hair Detection System
Applicable Claims: Hair regrowth, increased hair density, and improved hair thickness.
TrichoScan® is a hair density evaluation system that combines image analysis technology with software algorithms. It can quantitatively measure hair density per unit area (cm²/in²) after hair regeneration treatments.
Trichogram Hair Analysis Technology
Applicable Claims: Reduction of hair loss; reduction of shed hair by X%.
Trichogram is a microscopic hair analysis method used to evaluate hair health by examining hair follicles and identifying the proportions of hairs in different growth phases, including the anagen, catagen, and telogen phases.
Comprehensive Research Design Customization Plan
(1) Anti-Hair Loss Research (Anti-Hair Loss Evaluation)
This protocol applies to products primarily designed to reduce hair loss and improve hair density. The test design includes:
Visual Evidence System (Before & After Photos):Records changes in hair volume before and after product use and evaluates improvements in scalp visibility through standardized photography.
Wash & Combing Test:Quantifies the number of hairs shed during shampooing and combing and evaluates changes in hair loss trends throughout product use.
Consumer Perception Research:Collects participants’ subjective feedback regarding perceived improvements, such as “reduced hair loss” and “stronger hair roots.”
(2) Anti-Hair Loss and Hair Regeneration Research
When a product is designed not only to reduce hair loss but also to stimulate follicular activity and promote new hair growth, a more comprehensive evaluation approach can be applied. The test design includes:
Visual Evidence System (Before & After Photos):Visually demonstrates changes in hair density and scalp coverage before and after product use.
Wash & Combing Test (W&C Test):Continuously monitors changes in hair shedding levels to evaluate anti-hair loss performance.
TrichoScan® Hair Analysis System:Using high-resolution microscopic imaging and automated recognition algorithms, this system measures hair density and growth rate per unit area (cm²/in²), providing quantitative evidence for hair regrowth efficacy.
Consumer Perception Research:Evaluates users’ subjective perceptions of improvements such as “increased hair volume” and “thicker hair.”
(3) Comprehensive Assessment of Hair Loss Prevention, Hair Regrowth, and Hair Cycle Extension
This protocol is designed for advanced hair care products and clinical-grade anti-hair loss products. Through multi-dimensional evaluation, it not only validates hair loss prevention and hair growth efficacy but also assesses whether the product can support hair cycle extension and follicular activity enhancement.
The test design includes:
Visual Evidence System (Before & After Photos):Tracks long-term changes in hair growth and provides visual evidence of increased hair density.
W&C Test + TrichoScan® + Trichogram Comprehensive Evaluation:Combines multiple assessment methods to provide comprehensive verification of anti-hair loss, hair growth, and hair health improvement effects.
Consumer Perception Research:Collects comprehensive subjective feedback regarding improvement experiences after long-term product use.
Common Types of Anti-Hair Loss Products
Hair Care Products:Anti-hair loss shampoos, anti-hair loss conditioners, hair loss treatment masks.
Hair Growth and Scalp Care Products:Anti-hair loss serums, hair growth serums, scalp treatment lotions.
Nutritional Care Products:Scalp massage oils.
The evaluation of anti-hair loss products has evolved from subjective perception toward scientific quantification. As concerns related to “hair volume anxiety” continue to increase, only scientifically validated claims supported by reliable data can truly gain consumer trust and transform promises of “more, stronger, and longer-lasting hair” into measurable results.
Scalp health represents a new frontier in hair care science. A comprehensive scientific validation framework not only supports product efficacy claims but also strengthens brand credibility. Precision, efficiency, and wellness will continue to guide the future development of scalp care.SATISFY provides one-stop scalp efficacy verification solutions.
