Hair Structure

Hair is considered simple in structure. It is 95% made of a tough protein called Keratin. 
Keratin is considered insoluble in water and synthesized by keratinocytes. It ensures hair impermeability and protection. It is rich in cysteine, a sulfurated amino acid that forms the disulfide bonds between molecules, adding rigidity and resistance to the entire hair structure.
Hair also contains Melanin, the pigment responsible for hair color.
The regular hair growth system has three phases. Anagen represents the growing phase, catagen represents the transitional phase, and telogen represents the falling phase.
