Hair damage split ends

Conditioners can be made from oily surfactants or fatty surfactants, or a mixture of both. The more solid fatty conditioners can glue together split ends and damaged hair. The more liquid oily conditioners smooth the hair and then rinse out more effectively. 

Proteins and their hydrolysates are another class of conditioning agents these include materials derived from animals and vegetables, such as keratin, collagen, elastin, silk, soy, corn, and wheat. They can be used to protect and repair damaged hair, including the temporary mending of split ends. ... 

Proteins are claimed and proved to increase the tensile strength of hair, increase elasticity, impart body and softness, help repair split ends and cuticle damage, and protect from the adverse effect of detersion, chemical waving, and bleaching. Different protein derivatives are selected for specific hair treatments and products. Commonly used dose ranges in different hair care formulations are listed in Table 6.
