How Hair straighteners are Made

Hair straighteners work by breaking the hydrogen bonds in the hair that cause the hair strands to bend and become curly. Once these bonds are broken, hair is temporarily straightened until it comes in contact with water or humidity and the bonds are restored. Hair straighteners are made in a similar way to regular clothing irons. A straightener consists of two metallic rods that are heated by an electric current. The rods transfer this heat to the two metallic or ceramic plates of the tong-shaped straightener. The rods are carefully concealed inside plastic shafts to prevent users from burning their hands or injuring themselves.
