All synthetic hair colors used on wigs and hairpieces are standardized according to how many colors in the hair color ring used by manufacturers?

The correct answer is based on industry standards where manufacturers have established a color ring that comprises 70 standardized synthetic hair colors. This allows for consistency and a reliable reference for both consumers and professionals in the field. The 70 colors cover a wide spectrum of shades, offering diversity and versatility for wig and hairpiece creation.

Having a standardized color ring is essential because it helps hairstylists and manufacturers match hairpieces with clients' natural hair tones or desired looks accurately. Furthermore, this standardization facilitates the ordering and production processes in the hair extension industry, ensuring that clients can expect certain shades to look the same across different products and manufacturers.
