This analysis found that women preferred men with beards for short-term relationships and clean-shaven men for long-term relationships, while men preferred long-haired women for long-term relationships but had no preference for short-term relationships.

This study found that hair cortisol concentration in free-ranging brown bears is influenced by handling methods, body condition, and potentially both short- and long-term stressors.

This study describes the successful management of Andean bear alopecia syndrome in three female bears using oclacitinib, leading to rapid pruritus resolution and fur regrowth without adverse effects.

This study found that human beard hair follicles metabolize dehydroepiandrosterone into various compounds at significantly higher rates than those reported for human skin, suggesting unique metabolic processes in hair follicles.

This study found that DEB-BACE combined with systemic chemotherapy was more effective than chemotherapy alone for unresectable lung squamous cell carcinoma, reducing side effects and improving survival rates.

This review reports limited evidence on topical treatments for beard enhancement, with topical minoxidil, testosterone gel, and tretinoin showing potential but requiring further study.

This study found that exosome injections from human umbilical cord, with or without polydeoxyribonucleotide, promoted regrowth and repigmentation of white beard hairs and improved scarring in a 35-year-old man with refractory alopecia areata, suggesting potential as a minimally invasive regenerative treatment.

This review summarizes the use of fecal glucocorticoid metabolite analysis to monitor stress across various bear species and reports no new clinical results.

This study observed that cells from androgen-sensitive areas like the beard and scrotum showed higher androgen receptor levels compared to those from non-balding scalp areas, supporting the role of dermal papilla in follicle growth responses to androgens.

In this study, cosyntropin-induced cortisol spikes did not affect hair cortisol concentration in captive grizzly bears, contrasting with stress responses observed in free-ranging bears during capture.

In this study, researchers reported that applying topical 7.5% dapsone led to a significant decline in lichen planopilaris activity within a month and a sustained two-year remission in a patient intolerant to other treatments, suggesting dapsone as a promising alternative for managing this condition.

This study developed a nanohydrogel containing itraconazole and mometasone for treating scalp and beard fungal infections, demonstrating improved antifungal efficacy, longer retention, and better patient acceptance compared to conventional treatments.

In this case study, a 55-year-old male farmer from Nepal with a kerion barbae in the beard region showed complete resolution after initiating oral itraconazole, highlighting the potential for misdiagnosis when bacterial superinfection complicates dermatophyte infections.

This study found that certain polymorphisms in EGF and EGFR genes may increase susceptibility to alopecia areata in the Korean population, and these genetic variations could be associated with specific symptoms such as nail involvement and body hair loss.

This study found that both epithelial and hair keratins are expressed in beard hair medulla cells, exhibiting unique patterns and interactions distinct from other hair follicle and epithelial cells.

This study examined the skin structure of European Brown Bears, finding that the thickest skin is on the back and the thinnest on the ventral abdomen, with distinct layers and fiber networks.

This study found that measuring reproductive hormone levels in brown bear hair may effectively support non-invasive genetic sampling, though larger samples or more sensitive techniques are needed for broader application.

In this study, adding δ34S isotope analysis to models modestly improved precision in estimating grizzly bears' salmon and terrestrial diets, but contributed little new information.

This study found that night shift work disrupts clock gene expression in Japanese men, particularly affecting rhythms and levels of Period3 and Nr1d2, based on the shift schedule.

This study introduces a spherical skin model that effectively mimics key features of human skin, offering a scalable and rapid alternative for non-animal dermatological and cosmetic testing.

This study aims to assess the real-world effectiveness of baricitinib, a JAK inhibitor, for promoting regrowth of nasal, genital, and beard hair in patients with severe alopecia areata, expanding on findings from the BRAVE-AA clinical trial. Results are not reported.

This study found that methanol is more effective than isopropanol at removing external cortisol from grizzly bear hair and suggests that the choice of solvent can influence hair cortisol concentration results.

In this study, researchers found that adults with alopecia areata exhibited trichoscopic features of empty follicular openings and tulip hair, while children showed more honeycomb pigment patterns and pohlpinkus constriction on their scalp lesions.

This study found that hair transplantation for head and neck scar alopecia was targeted based on scar characteristics, with follicular unit extraction often preferred for less extensive graft needs.

This study found that hair transplantation techniques, particularly follicular unit extraction (FUE), were effective for head and neck scar alopecia, with method selection based on scar type and depth.

This review discusses facial hair transplantation techniques for natural-appearing results in restoring eyebrows, beards, goatees, sideburns, and repairing alopecic scarring, reporting no new clinical results.

This study reported that follicular unit extraction using nonhead hair sources like the chest or beard may successfully restore hair density and achieve aesthetically pleasing results in severely bald men with limited head donor hair.

This review discusses the use of follicular unit extraction for hair restoration using body hair, reporting no new clinical findings, and highlights its potential for advanced baldness cases with limited scalp donor hair.
