Every woman has a dream of having lustrous and healthy hair. Hair catches the attention of everybody. We can completely change our look by changing our hair style. Many of us think why we don’t have same kind of hair. Actually hair is primarily composed of a protein keratin which grows from a sac called the follicle. Hair follicle cells generate keratin and other proteins which become the part of hair shaft. They contain sulphur atoms and when two of these sulphur atoms pair up and bond, they form a disulfide bond. In the same protein, if two sulphur atoms are at a distance and join to form the disulfide bond, the protein will bend. The way protein structures are arranged in each hair shaft effect how hair behaves. The more disulfide bonds that occur between hair proteins, the curlier the hair and vice versa.
Everybody can alter their hair style to force it into a straight state or a curly state with water and heat. But this is only on a temporary basis not permanent. It can be done by breaking the bonds in disulphide chemically. To know more such interesting facts on science and technology, you can find by visiting: www.classontheweb.com
