Nut Job vs Toppik vs Caboki

Keratin is found throughout the animal kingdom in wool, horns, feathers, claws and hooves. It is from these sources that most keratin hair product manufacturers synthesise their keratin. So whilst you may believe that you are buying something that closely resembles or imitates human hair, you are more than likely buying animal products.

Synthesising keratin from animal parts makes keratin an ‘animal protein’ which means it naturally contains a large amount of bacteria. In order to turn the animal protein into a safe cosmetic product, significant amounts of bactericides and preservatives are required. Adding more chemicals.

In addition, keratin is water soluble and when you shake some keratin hair fibres into a glass of water you will see the water turn instantly green. This is because the fibre cannot hold the colour when in contact with liquids.

This is why some people report that keratin fibres turn green in the sun and in sweat.
