Human scalp hair: geometry, biochemistry, growth parameters and mechanical characteristics
Scalp hair is increasingly being used as a testing substrate for toxins and monitoring treatment adherence. The biochemistry of human hair is assumed to be similar; however, a recent study reported higher concentration of lipids in African hair. The effect of hair curvature, if any, on drug …

An investigation of the association between structural proteins and lipids with scalp hair curvature
Scalp hair is increasingly being used as a non-invasive analytical sample in diagnostic and forensic medicine. However, variable sensitivities for detection of hair biomarkers were observed, whereby African hair generally incorporated higher drug levels than Asian and Caucasian hair types. It was …

Evaluating the impact of ultraviolet light on chemical and mechanical properties of human scalp hair through controlled and natural experiments
Introduction: Human hair fibres have been studied in a variety of fields for different applications. Examples include the use of hair as a medical testing substrate for diagnosis of pathologies, as a tool for forensic investigations, a substrate for cosmetic product development and as a precursor …

The roles of hepatocyte growth factor family members in androgen-regulation of human hair growth. A comparison of the expression of hepatocyte growth factor family members, HGF and MSP, and their receptors, c-Met and RON, in isolated hair follicles from normal and androgenetic alopecia (balding) scalp.
Androgens are the main regulators of human hair growth stimulating larger, terminal hair development e.g. beard and causing scalp balding, androgenetic alopecia. Hair disorders cause psychological distress but are poorly controlled. Androgens probably act by altering regulatory paracrine factors …

The use of hair detect (and monitor) chronic hyperglycaemia
… long term glycaemic control may be useful. Since scalp hair consists of about 80% protein, which is subject to non-enzymatic glycation, and growing hair has a rich blood supply exposing it to free glucose, it is likely that hair can be used as an alternative substrate for monitoring chronic …
