WebDec 19, 2024 · Disulfide and hydrogen bonds The combination of dynamic disulfide and hydrogen bonds is a common self-healing method. Disulfide and hydrogen bonds, which function in concert as hard segments in the structure of PU, can have characteristics resembling those of a conjoined covalent adaptive network. 65 Hydrogen bonds can act … WebFeb 6, 2024 · Chemical bonds stitch these proteins together, giving it strength and rigidity. In healthy hair, these bonds—known as disulfide bridges—are secure and unbroken. But daily life takes its toll: Too much exposure to sunlight and products such as bleaches, straighteners, and dyes breaks the disulfide bridges, making hair brittle.
