Why Length Disputes Happen

Different people often measure straight, wavy and curly products differently. The measuring method should be defined during sample approval.

Straight Hair Measurement

Measure from the agreed start point to the longest natural end using the approved method.

Wavy and Curly Hair Measurement

Specify whether textured hair is measured naturally or gently extended. Use the same method for sample approval and bulk inspection.

What the Specification Should Record

Nominal length; measurement start point; natural or extended state; tolerance; layer treatment; reference photos where useful.

Length and End Fullness Are Different

A product can reach the nominal length while still having weak or thin ends. Inspect both.
