Chemistry's Role

The 2 main  components in horse hair is keratin and amino acids. The amino acids and the keratin and create polypeptide chain to create each strand of hair. As these form naturally made by your body create either thick or thin hair. Each strand has a protective layer of keratin that creates a barrier from the outside weather. The final product of hair is not man made it is naturally occuring in nature. Chemistry's main role happens when the foal is forming in the mother at the late stages of development hair starts for be made as a product of the mother giving the amino acids and keratin to the child. 


Background Research

Horses have been used as social experiments and have been sent to slaughter hoses for the meat on their bones. Equine hair has been used for 19th century chairs or couches and paint brushes because of the coarseness/stiffness that makes a great calligraphy brush and it is used for clothes in switzerland. Now in modern times horse hair is used for bracelets and necklaces along with home decor. At one point on history horse hair was used for fishing lines.
