Diffraction of light by the cuticle structure of hair.

Journal of cosmetic science, 2007
Under a microscope, hair looks like a surface relief grating with an irregular sawtooth profile. Using scalar diffraction theory, we model what has been, until now, assumed to be a specular peak in the light scattering data. Diffraction efficiencies are calculated as a function of cuticle thickness.

Characterization of the cysteine-rich calcium-binding S100A3 protein from human hair cuticles

Biochemical and Biophysical Research Communications, 2002
S100A3, a unique protein among all members of the calcium-binding S100 family, is specifically expressed at the inner endocuticle of human hair fibers. Upon hair damage, S100A3 is released from hair fibers and possibly destabilizes the hair tissue architecture.

[Architectonic and diagnostic significance of hair cuticle].

Izvestiia Akademii nauk. Seriia biologicheskaia, 2002
Guard hair and spine architectonic were studied in 345 mammalian species using scanning electron microscopy. Comparative morphological analysis of the author's and published data was performed to systematize the available information. Original terminology and classification of the main hair cuticle patterns have been proposed.

Age‐dependent damage of hair cuticle: contribution of S100A3 protein and its citrullination

Journal of Cosmetic Dermatology, 2015
SummaryBackgroundThere are two types of damage pattern of human hair cuticle: type L, where the cell membrane complex is split and the cuticle lifts up, and type E, where the fragile substructure of the cuticle cell (endocuticle) is broken. In our previous paper, it was reported that the dominant damage pattern shifts from type L to E with the subjects'

Mechanical extension of human hair and the movement of the cuticle.

Journal of cosmetic science, 2001
Goniophotometry has enabled measurement of the angle that the surface of the cuticle (the scales) of a human hair fiber makes with the axis of the hair shaft. This measuring technique has been used to obtain the change of this scale angle with extension of a hair fiber under fixed conditions of temperature and relative humidity. Based on a simple model

[Study of cuticle patterns of head hairs by scanning electron microscopy].

Sudebno-meditsinskaia ekspertiza, 2000
Cuticle patterns of 5 subjects living in different countries have been studied under a scanning electron microscope. Hair cuticle pattern in different individuals can be complex, simple, or mixed type. The most incident is the complex type of hair cuticle pattern (75-80%), while the simple type is much more rare (15-20%) and the mixed type still more ...
