Frizzy hair syndrome is frequent. It is due to sideways growth and tight coiling of the hair fiber. It is often secondary to unsuitable grooming practices causing ingrown hair (pili incarnati) followed by infection and\or damage. The fragility of frizzy hair promotes alopecia due to chronic traction, use of hair relaxers, and perming. Treatment of complications is difficult so awareness of precautionary measures is important.

Pili trianguli et canaliculi syndrome is a rare hair shaft disorder characterized by frizzy hair that cannot be smoothed flat. Affected hair shafts are triangular or kidney-shaped with longitudinal grooving. Diagnosis typically requires electron microscopy, which may be cost-prohibitive, or alternatively, the distinctive features of hair shafts can be identified through histological examination of cross sections, that is time-consuming.

Hair shape affects the frictional properties and tactile sensation of hair. In this study, we evaluated the friction associated with the rubbing of straight, curly, or wavy hair by a contact probe equipped in a sinusoidal motion friction evaluation system. This system provides dynamic information such as the velocity dependence and hysteresis of the frictional force.

Ostarine, also known as MK-2866 or enobosarm, is a selective androgen receptor modulator (SARM). It has anabolic properties and as such is widely used in doping, accounting in 2021 for 25 % of the adverse analytical findings (AAF) among the class S1.2 "Other anabolic agents" of products banned by the World Anti-Doping Agency, to which it belongs.

Background: Woolly Hair Syndrome (WHS) is a rare birth condition that affects the structure of hair in non-black people. The pathogenesis is not yet defined. It is postulated that the hair follicle's desmosomes (specifically desmoplaquine, placoglobin and placofilin-1, which are cell structural proteins that keep the adhesion among close cells) would be altered in this pathology, leading to fragility in the cellular union.
