This study suggests that human hair follicles may operate their own Cori cycle, synthesizing glycogen from lactate under conditions of lactic acidosis.

This study observed that in an ex vivo setting, 17β-estradiol increased CB1 expression in human hair follicles, suggesting possible sensitivity to endocannabinoids and a potential mechanism for hair therapy.

In this study, researchers observed significant morphological and histological differences in transplanted hair follicles compared to native donor follicles post-FUE hair transplantation for androgenetic alopecia, highlighting substantial variations in sebaceous gland and root sheath degeneration at the recipient site.

Androgen receptors found in monkey scalps, similar to humans, affect hair growth.

This study found that COX-2 expression in normal rat skin is linked to the hair cycle, with varying levels observed in different skin structures during anagen, catagen, and telogen phases.

Activating the Eda/Edar pathway improves wound healing by enhancing hair follicle growth.

This study observed dynamic changes in CD10 and CD34 expression in fetal and adult human hair follicles during embryogenesis and hair cycling.

This study found that PGF 2α receptors were predominantly present in the inner root sheath of the bulb and stem of human eyelashes during the anagen phase.

This study suggests that ADAM 10 and 12 proteases may play important roles in the regulation of hair cycling through their expression patterns in hair follicle structures.

Trichodysplasia spinulosa can occur after a heart transplant due to immunosuppressive drugs.

This study revisits and reproduces Felix Pinkus' concept of the vitreous membrane in hair follicles, suggesting these structures may play a role in differentiation or nutrition due to their location in metabolically dynamic regions.

This study observed that in Assam Hill Goats, the primary hair follicles had larger diameters and more structural associations compared to secondary follicles, especially in ruminant-age groups.

Using a transgenic pig model, this study demonstrated that LGR5 is a marker of hair follicle stem cells across different species, with important similarities and differences in gene expression and developmental processes.

This study suggests that finasteride's effect on promoting hair growth in men with androgenetic alopecia may be due to its inhibition of 5aR2 localized in hair follicles.

In this study, researchers developed a non-invasive method to distinguish exogen hair from telogen hair on the human scalp, finding that normal exogen hair levels are generally less than seven hairs per cm².

This study found that human scalp hair follicles can internally operate a Cori cycle, synthesize glycogen in the presence of lactate, and modulate growth through glycogen phosphorylase activity.

This study in Hexi cashmere goats found that secondary follicle activity increases with time, and Hoxc13 expression varies significantly across different growth stages, suggesting a role in follicle activity.

In this study, the reconstructed skin epidermal model derived from hair follicles showed gene expression and enzyme functionality consistent with native human skin, suggesting its viability for studying skin metabolism and potential toxicity of dermo-cosmetic ingredients.

This study presents a novel in vitro assay using human folliculoid microspheres to research hair growth, which may facilitate preclinical testing of hair growth-modulatory agents.

This exploratory study found that cannabidiol (CBD) at higher concentrations may inhibit hair growth by promoting the onset of catagen in human hair follicles, while lower concentrations showed potential anti-inflammatory effects without promoting catagen.

In this study, researchers found that p75 neurotrophin receptor signaling affects apoptosis during hair follicle regression in mice, and altering its activity might help manage disorders involving early catagen entry.

This study found that the vitamin D receptor is crucial for initiating the postnatal hair follicular cycle in mice, preventing alopecia associated with its inactivation.

This report describes two cases of sustained hair repigmentation related to porphyria cutanea tarda, though the underlying mechanism remains unclear.

This study found that when human hair follicles were grafted onto mice, they progressed through dystrophic stages and returned to normal growth, with stem cells aiding in recovery.

In this study, researchers used a rodent model to uncover key changes in how hair fibers detach, suggesting that the exogen phase should be subdivided based on club fiber status.

The authors report a rare case of trichilemmal carcinoma in the thigh of a 71-year-old, emphasizing the importance of complete surgical excision to prevent recurrence and support patient prognosis.

This study observed that vimentin and transthyretin proteins were more highly expressed in black sheep skins compared to white, suggesting their involvement in coat color formation.

TNF-a may not be as involved in certain types of hair loss as previously thought.

This case report describes dermoscopic features of pemphigus vulgaris on the scalp, highlighting that hair casts may suggest treatment adjustment for improved disease control.

This study found that hair canal and follicle diameters, outer root sheath area, and terminal-to-vellus hair ratios were significantly reduced in androgenetic alopecia patients compared to normal controls.
