2025年9月12日

Wig products, as important products for hair styling and grooming, their quality directly affects the usage effect and the health of consumers. For purchasers, brand owners, and quality control professionals, establishing a comprehensive supplier evaluation system and product acceptance standards is of utmost importance. This article will systematically elaborate on the quality inspection standards, production monitoring processes, and professional inspection methods for wig products.
I. Source Control: Key Points for Factory Evaluation of Wig Manufacturers
Before making bulk purchases, conducting a comprehensive review of the manufacturer's qualifications is the foundation for ensuring product quality.
Production qualification certification:
Has the factory obtained the ISO9001 quality management system certification?
Do you have a cosmetics production license (for hair care products)?
Does it have a complete raw material inspection (IQC), process supervision (IPQC), and finished product inspection (FQC) procedure?
Production process capability:
Evaluate the technical proficiency of key processes such as hair processing, knitting techniques, and dyeing methods.
Check whether professional equipment such as hair strength testers and color fastness testing devices are available.
Confirm the control of cleanliness in the production environment and the management of temperature and humidity
Laboratory testing capabilities:
The factory laboratory should be capable of conducting hair composition analysis, color fastness tests, and flame retardancy tests.
Ensure that the detection equipment is regularly calibrated and in an operational state.
The laboratory has been verified to meet the requirements of relevant national standards (GB/T23170-2008)
Raw material control:
Verify the qualification certificates of the suppliers of hair fiber materials
Confirm that the dyes and chemicals meet environmental protection and safety standards
Inspect the quality and safety of the net bottom material
II. Finished Product Inspection: AQL Sampling Inspection Standard Process for Hair Extensions
The inspection of hair extensions should follow the AQL sampling standards (usually LEVEL II) and conduct random sampling, covering multiple aspects such as appearance, material, craftsmanship, and safety.
1. Packaging and Label Inspection
Packaging materials: Check the integrity and protective properties of the outer packaging.
Product identification: Verify that the information such as material description, size specifications, color codes, and compliance standards is accurate and clear.
Instruction Manual: Includes information on wearing method, cleaning and maintenance instructions, and precautions.
2. Appearance Quality Inspection
Hair quality:
Check the consistency of the luster and smoothness of the hair strands.
Check for uniformity of hair color, with no color difference.
No knots, no messy hair strands
Process Quality:
The knitting density is uniform and there is no missed knitting.
The hairline is natural and has no mechanical marks.
The net base material is flat and free from any damage.
3. Material Safety Inspection - Key Test Items
Hair material:
Verify the authenticity of the material of the hair sample or synthetic fiber hair strands
Check that the diameter and elasticity of the hair strands meet the standards.
Netting material:
Check the ventilation and comfort of the bottom of the net.
Confirm that the materials are non-toxic, harmless and non-irritating.
Safety of auxiliary materials:
Hair clips, adhesives and other accessories are safe and harmless.
No sharp edges, no safety hazards
4. Performance Testing
Color Fastness Test:
Resistance to color fading under sweat test
Friction resistance color fastness test
Durable wash fastness test
Strength test:
Hair tensile strength test
Knitting strength test
Life span assessment
Flame retardant performance:
Flame-retardant test for synthetic fiber threads
Compliant with relevant safety standards
5. Comfort Test for Wearing
Size Compatibility:
Head circumference measurement accuracy check
Detection of depth and length deviation at the front and back
Air permeability test:
Evaluation of the ventilation performance at the bottom of the net
Long-term wearing comfort test
Weight test:
The overall weight meets the standard requirements.
No feeling of heaviness when wearing
III. Quality Grade Determination Criteria
1. Premium Grade
Material: 100% human hair or high-quality synthetic hair
Process: Hand-knitting, uniform density
Fastness to color: Grade 4 or above
Service life: Does not deform even after long-term use
2. Qualified Product
Material: High-quality synthetic fiber hair strands
Process: Mechanical manufacturing, with excellent craftsmanship.
Fastness to color: 3-4 grades
Service life: Normal usage period
3. Defective product
Material: Low-quality synthetic fiber hair
Process: Obvious defects, uneven density
Fastness: Below Grade 3
There are safety hazards.
IV. Classification of Common Defects
Serious Defects: False material, toxic and harmful substances, severe color difference, excessive hair loss
Main defects: Process flaws, poor color fastness, size deviation, and uncomfortable wearing.
Minor defects: Minor appearance flaws, slight packaging issues, small errors in labeling
V. Inspection Rules and Criteria
Sampling plan: Based on the batch size, the sampling quantity is determined according to the AQL standard.
Defect determination:
If any serious defects are found, the entire batch can be judged as disqualification
(unqualified).
The number of major defects exceeded the AQL acceptance limit, so it was determined to be non-compliant.
The performance parameters exceed the tolerance range, and are judged as unqualified.
Report Output: The detailed inspection report should include the sample size, test data, defect description, and test results.
Conclusion
The quality inspection of hair extensions products requires professional knowledge and strict testing procedures. By evaluating the suppliers, it is ensured that the manufacturers have reliable production capabilities. Then, through the final product acceptance before shipment, a comprehensive performance verification of the products is conducted to form a complete quality assurance system. Purchasers and brand owners should particularly pay attention to the tests of material safety and wearing comfort to ensure that the products meet the quality requirements and provide consumers with safe and reliable products.
