What distinctive result occurs when burning a human hair wig?

When burning a human hair wig, it produces a distinctive color due to the presence of proteins in the hair structure that react during combustion. Human hair contains keratin, and when it is burned, the combustion process can produce a particular hue that is often associated with organic materials. This characteristic behavior distinguishes human hair from synthetic fibers, which may melt or burn differently and do not exhibit the same color variations.

The different reactions observed when burning hair include the sweet odor it might give off and the way in which it burns, but the defining feature that sets human hair apart in this context is indeed the distinctive color change that occurs during burning. This visual characteristic is significant for professionals in cosmetology, as it aids in the identification of hair materials, especially when determining the quality and type of wigs or extensions.
