A nswer: Hair provides no vital function but does protect the surface of the skin, conserves body heat, and contributes to self-image. Hair is associated with femininity (e.g., long hair) and masculinity (e.g., facial hair) and, for many, closely associated with sexuality (DeVillez, 2003; Ehmann, Sheehan, & Decker, 1991). Although not considered life threatening, chemotherapy-induced hair loss ...

The ability of Protein disulphide isomerase (PDI) to promote the grafting of two cysteine-containing peptides onto hair was investigated in order to develop an alternative treatment for over-bleached hair. The studied peptides were designed based on human keratin and human lung surfactant proteins and were linked to a fl uorescent dye to facilitate visualisation of the grafting process and to a...

Consumers use different hair care products to change the physical appearance of their hair, such as shampoos, conditioners, hair dye and hair straighteners. They expect cosmetics products to be available in the market to meet their needs in a broad and effective manner. Evaluating efficacy of hair care products in vitro involves the use of highly accurate equipment. This review aims to discuss ...

Paraphenylenediamine (PPD) is a widely used chemical in various hair dye formulations. Due to its cheap price and easy availability, it emerges as major cause of suicidal poisoning. It carries high morbidity mortality does not have any specific antidote. We reported an unusual type poisoning 44-year-old man with PPD how he was managed excellent outcome.

2,6-diaminopyridine is extensively used as a pharmaceutical intermediate and a hair dye coupler as oxidation formulations. it is soluble in protic solvents. primary and secondary amines are n-methylated by various methods such as direct alkylation of amines with hofmann mechanism, but in many of these methods due to overalkylations, we earn a mixture of amino products. consequently, they aren't...

Allergic contact dermatitis (ACD) is the most prevalent form of immunotoxicity in humans characterized by clinical manifestations such as red rashes, itchy skin and blisters. The disease is caused by skin sensitizers which are allergenic low-molecular weight chemicals. ACD is an important occupational disease that gives problems at different workplaces, including hair dressers, metal workers, c...

Mechanosensitive hair cells and supporting cells comprise the sensory epithelia of the inner ear. The paucity of both cell types has hampered molecular and cell biological studies, which often require large quantities of purified cells. Here, we report a strategy allowing the enrichment of relatively pure populations of vestibular hair cells and non-sensory cells including supporting cells. We ...
