Strong beautiful hair is universally desired across various cultures. Hence, the ways in which cleaning conditioning, grooming and styling processes affect the strength, feel and manageability of hair is of interest to beauty care science and technology. Human hair is a complex nanocomposite biological fiber. In this thesis, experiments are performed to better understand mechanical and electric...
Background: Due to the presence of radioactive minerals such as monazite, the beach sand of the west coast of Kanyakumari exhibits high natural background radiation. Hair is a good indicator of radionuclides in the human body. An attempt is taken to measure the 210Po activity in human hair samples and the factors affecting it. Material and Methods: 210Po activity was analysed in 47 ind...
The concentrations of trace metals in hair of fishermen from the Persian Gulf region were assessed todetect the relationships between element levels in hair and potential factors influencing these relationships.The hair of 19 fishermen were sampled from six stations in the Persian Gulf (Nirogah, Dayyer, Lengeh and Bandar Abbas in Khuzestan, Bushehr and Hormozgan provincesanalyzed by Inductively...
a user-friendly and inexpensive ionic liquid-based single-drop microextraction (il-sdme) method was developed to preconcentrate trace amounts of aminophenol isomers (aps) from human urine, hair dye and water samples prior to analysis by high performance liquid chromatography-ultraviolet spectrophotometry detection (hplc-uv). under optimum conditions (i.e., 3.5 µl of 1-hexyl-3-methylimidazolium ...
Hair follicles (HFs) undergo lifelong cyclical transformations, progressing through stages of rapid growth (anagen), regression (catagen), and relative "quiescence" (telogen). Given that HF cycling abnormalities underlie many human hair growth disorders, the accurate classification of individual cycle stages within skin biopsies is clinically important and essential for hair research. For precl...
Various healthcare guidelines are presented in Islamic tradition regarding human health, one of which is about hair care. The current study aimed to analyze the cleaning and washing approach in hair care with cleansers, such as Henna, Cedrus, Hibiscus, and Katam (Buxus dioica) and their curative and hygienic role. In addition, some dimensions of the medical instructions of the narratives concer...
Dermal papilla cells (DPCs) in the mammalian hair follicle have been shown to develop hair follicles through epithelial-mesenchymal interactions. A cell therapy to regenerate human hair is theoretically possible by expanding autologous human DPCs and transplanting them into bald skin, though much remains to be overcome before clinical success. In this study, we compared gene signatures of human...
Hair morphology is one of the most conspicuous features of human variation. The hair follicle has attracted significant attention as a model for the investigation of diverse biological problems. Whereas, very little is known about the genes influencing the morphology and structure of the hair shaft. Curly hair is very common character of hair phenotypes of human, while most congenital curl occu...
