Hair Length

The specified hair length on training heads can sometimes be misleading, as different suppliers use different measurement methods. Using diagrams, we present the 3 most common methods worldwide:

1. In the first method, length is measured from the front hairline over the crown to the nape.
2. In the second method, length is measured from the crown down to the longest tip in natural fall.
3. In the third method, actual lengths at multiple head points are recorded. The final value refers to the longest hair and is measured at a 90° angle.

How do we measure hair length?
We use both method 2 and method 3 to ensure transparency. We always indicate the method used and provide total or detailed lengths. Diagrams clearly show the structure and length positioning across the head.

Indian human hair

Indian human hair has a round to slightly oval diameter and a thickness of approximately 0.08–0.12 mm, making it only about twice as thick as European hair. It is primarily available in natural shades ranging from black to brown. Thanks to its natural movement, it closely resembles European hair. The raw hair comes from voluntary donations in temples and is collected by certified traders.
