This systematic review concluded that the support for using spironolactone at commonly prescribed doses is based on evidence of limited quality.

In this systematic review and meta-analysis, PRP therapy significantly improved hair density and thickness for women experiencing hair loss, with mild and transient adverse effects, suggesting potential tailored treatment protocols based on dosage, injection duration, and ethnicity.

This study achieved a first by successfully forming large quantities of dermal papilla spheroidal microtissues, which retained their hair induction potential, using a micropatterned culture system.

This study found that tight junctions extend to the most superficial layer of the stratum granulosum in human skin, challenging previous claims of their limited presence in the epidermis.

This study found that neurosteroids and benzodiazepines decrease network excitability in neuronal cultures, with specific long-term depressive effects on inhibitory neurons.

In this in-vitro study, researchers found that shampoo-induced coacervates structurally resemble cationic polymers and contain anionic surfactants that may stimulate the scalp upon exposure to water.

This case study reports that treating a female patient with facial partial unilateral lentiginosis using a 532-nm Nd:YAG fractional picosecond laser resulted in significant improvement in pigmentation without notable side effects, indicating it may be an effective and well-tolerated treatment option.

This study found that local PGE2 injection may prevent radiotherapy-induced hair loss by protecting hair follicle cells and promoting hair follicle self-repair.

This study found that inhibiting the Mitochondrial Pyruvate Carrier in human hair follicles ex vivo activated the integrated stress response, affecting cell proliferation and metabolism.

This study highlights that stress-induced activation of the HPA axis in human hair follicles can lead to hair growth arrest, but variability in follicle response complicates potential therapeutic approaches.

This study in Tehran found that, after adjusting for confounders, women with PCOS had no different risk of non-pregnancy after assisted reproductive treatment compared to women without PCOS.

This study found that skin fibroblasts in mice arise from two distinct lineages which contribute differently to dermal structure and repair, impacting hair follicle formation during wound healing.

Nephronectin helps attach muscle cells to hair follicles.

This study demonstrates the potential of using bioengineered follicles from adult tissue-derived stem cells for fully functional hair regeneration, illustrating possible applications in organ replacement therapy.

This review discusses the histopathology of male-pattern baldness and highlights ongoing disputes over several aspects, including sebaceous gland size and follicle loss, reporting no new clinical findings.

This review examines the literature on the molecular and cellular makeup of the hair follicle niche and how it influences stem cell behavior during hair regeneration, but does not provide new experimental results.

In this study, the researchers observed that male pattern alopecia is characterized by miniature follicles, enlarged sebaceous glands, and an increased number of mast cells, without significant abnormalities in enzyme activity.

This study found that sympathetic nerves and arrector pili muscles form a niche that modulates hair follicle stem cell activity, revealing their role in hair follicle regeneration.

In this study, key histologic features such as mucinous perifollicular fibroplasia were identified to aid in the diagnosis of lichen planopilaris.

This study demonstrates that PAD1 and PAD3 are involved in hair follicle differentiation, while PAD1 and PAD2 may play a role in the physiology of sweat glands and arrector pili muscles.

This study demonstrated that bioengineered hair follicles reconstituted from embryonic skin cells and transplanted into hosts can restore physiological hair functions, suggesting potential applications for treating alopecia.

This study found that women with androgenetic alopecia experience diffuse hair loss due to a decrease in terminal hairs and an increase in vellus hairs per follicular unit.

This article discusses the phases and histological features of alopecia areata and reports no new clinical findings; the authors emphasize recognizing these phases for accurate diagnosis.

This review discusses the cardiovascular risks associated with anabolic-androgenic steroid use and reports that, despite known toxic effects, further research is needed to clarify the causality of these risks.

This review synthesizes current knowledge on eyelash hair follicles, highlighting gaps in understanding their biology and proposing future research directions; it reports no new experimental findings.

This study presents a new model for androgenetic alopecia progression, explaining diffuse hair loss in women through 3D reconstructions of the arrector pili muscle and its relationship with the hair follicle stem cell niche.

This study found that Merkel cell clusters require Frizzled6 signaling for their polarity information, while other hair follicle-associated structures align their orientation based on the hair follicle itself.

This study found that premature desquamation of the inner root sheath is a non-specific histologic feature in scarring alopecia and cannot be used alone to define central centrifugal cicatricial alopecia.

This study explored hair follicle gene expression in Inner Mongolia Cashmere goats and identified potential regulators of the transition between growth phases, including IL17RB and ZNF genes.
