A study of damaged hair
نویسنده
چکیده
Synopsis--A SCANNING ELECTRON MICROSCOPE study of the morphological changes in human HAIR has revealed that these changes may be entirely attributable to the ABRASION normally associated with hair grooming. In particular, SHAMPOOING and BRUSHING can produce all of the observed changes detected in virgin hair. These changes are more deleterious in some cosmetically altered hairs. This appears to be attributable to a decrease in the disulphide bond content of these fibres, this decrease being brought about by the cosmetic treatment.

Abstract Background: Follicles are part of epidermis and pass through a cell cycle. The result of this cell division is producing hair. Follicles specially growing follicles are very sensitive against irradiation and are damaged by low dose rates. So in this study investigated the relationship between chronic exposure of radiation workers and their hair loss. Materials and methods: In this stud...

The mammalian cochlea is a highly complex structure which contains several cells, including sensory receptor or hair cells. The main function of the cochlear hair cells is to convert the mechanical vibrations of the sound into electrical signals, then these signals travel to the brain along the auditory nerve. Auditory hair cells in some amphibians, reptiles, fish, and birds can regenerate or r...

Mannosylerythritol lipids (MELs), are produced from feedstock by the genus Pseudozyma, and are the most promising biosurfactants known due to its versatile interfacial and biochemical actions. In order to broaden the application in cosmetics, the hair care properties of MELs were investigated using damaged hair. On electron microscopic observation, the damaged hair was dramatically recovered wi...

متن کاملStructural changes in cuticles on violin bow hair caused by wear.
A bow with horse tail hair is used to play the violin. New and worn-out bow hairs were observed by atomic force microscopy. The cuticles of the new bow hair were already damaged by bleach and delipidation, however the worn-out bow hairs were much more damaged and broken off by force, which relates to wearing out.
