“…This is in contrast to trunk follicles in humans, in which the duration of the telogen phase can equal, or last longer than, the period of growth (Saitoh et al, 1970;Seago and Ebling, 1985). If not to be shed, but to be actively retained, club fibers are firmly anchored in the follicle, with the force required to remove them being similar to that required to extract an anagen fiber from its follicle (Chapman, 1992;Roersma et al, 2001).…”

The hair follicle has the unique capacity to undergo periods of growth, regression, and rest before regenerating itself to restart the cycle. This dynamic cycling capacity enables mammals to change their coats, and for hair length to be controlled on different body sites. More recently, the process of club fiber shedding has been described as a distinct cycle phase known as exogen, and proposed to be an active phase of the hair cycle. This review focuses on the importance of the shedding phase of the hair cycle and, in the context of current literature, analyzes the processes of club fiber formation, retention, and release, which may influence progression through exogen, particularly in relation to human hair.

“…Finally, we were eager to check the hair elasticity following the text product application. Human hair's elasticity is a vital characteristic since it indicates its internal structure and is strongly associated with hair characteristics, such as smoothness and softness [25,26]. Our hair elasticity results demonstrate that the hair elastic modulus (MPa) of the test (mixture 2) group human hair tresses and the control group human hair tresses significantly increased after 4 weeks of use.…”

Although hair loss plays a vital physiological function in present society, their impact on shaping self-esteem is undeniable. Even though there are numerous synthetic drugs available, these days, there are issues with safety, efficiency, and unclear time settings for required outcomes with the current synthetic drug remedies available; therefore, there is growing attention to discovering alternative methods to fight hair loss, primarily through plant-derived formulations. While earlier reports mostly focused on screening compounds or plant extracts affecting 5α-reductase, our research takes a unique direction. We employed a biochemical and molecular biological approach by delving into the complicated biosynthetic pathways involving 17β-hydroxysteroid dehydrogenase (17β-HSD) and 3β-hydroxysteroid dehydrogenase (3β-HSD) in producing testosterone derived from cholesterol. This process conceded requiring experimental results, posing insights into the control of the testosterone/dihydrotestosterone (DHT) production pathway. Our study confirms a discovery platform for finding potential candidates as hair loss inhibitors, highlighting exploring various biochemical mechanisms involving 17β-HSD and 3β-HSD in combination with medicinal plant extracts.
