Keratin itself is transparent in its purest form. However, keratin is often found in a blackish or clearish state when found in the claws and horns of mammals. This is due to the way keratin is produced, which can lead to pigmentation.
Keratin is a protein that forms hair, nails, and the skin's outer layer. It provides support and helps with healing. Keratin is also used in hair care products, such as shampoos, conditioners, and styling products. In hair color products, keratin is used to enhance the color and reduce breakage.
Keratin can also be found in hair extensions, where it acts as a bonding agent for fusion extensions. Keratin bonding glue pellets come in a variety of colors, including color 8.
While keratin itself is transparent, the presence of pigments and other factors can give it a variety of appearances.
