This review summarizes biological links between aging and androgenetic alopecia, particularly focusing on cellular senescence, and discusses potential therapeutic strategies, but reports no new clinical results.

This report presents a rare case of trichoadenoma occurring in the vulva, adding to the limited instances documented in medical literature.

In this study, researchers observed that TCDD exposure in mice enhanced sebaceous gland differentiation and lipid production before causing seboatrophy, providing insights into the cellular events that may contribute to chloracne pathogenesis.

This review discusses loose anagen hair syndrome in children, characterized by non-scarring alopecia and increased hair shedding, and reports no new results; topical minoxidil may be used as a treatment.

This study using human and animal models found that adipose-derived stem cell exosomes promoted hair growth and counteracted dihydrotestosterone's inhibitory effects, suggesting potential therapeutic applications for androgenetic alopecia.

In this study, researchers identified PSENEN mutations that can lead to a form of Dowling-Degos disease, characterized by follicular hyperkeratosis and an increased susceptibility to acne inversa, especially in the presence of certain trigger factors.

This paper reports a case of alopecia triangularis congenita in a 22-year-old woman, combined with androgenetic alopecia, and highlights successful treatment with internal and topical antiandrogens.

This source reviews a range of sebaceous gland disorders, exploring their clinical characteristics, risk factors, and common treatments, including conditions such as sebaceous gland hyperplasia and acne vulgaris, and highlighting various therapeutic approaches.

This case report describes a 14-year-old girl with signs of virilization, including increased facial and body hair, deepened voice, and elevated serum testosterone and androstenedione levels.

In this study, treatment with DHEA induced mild to moderate hyperplasia of sebaceous glands in ovariectomized rats, which was prevented by the antiandrogen Flutamide but not by the antiestrogen EM-800.

This case study highlights a testosterone- and cortisol-secreting adrenal oncocytic neoplasm in an 18-year-old woman, illustrating the role of surgical excision in resolving hyperandrogenism and restoring menstruation.

In this study, topical dehydroepiandrosterone (DHEA) doubled sebum production in women without systemic side effects, suggesting it may be a safe treatment for reduced sebum output related to menopause.

In this study, estetrol (E4) treatment was associated with increased hair growth in ex vivo human hair follicles, suggesting its potential as a treatment for hair loss disorders.

This study found that inhibiting AP-1 activity in mice modified tumor development, leading to transdifferentiation between squamous and sebaceous tumors, with molecular analysis suggesting AP-1's role in maintaining tumor cell identity.

This chapter reviews signaling pathways related to androgenic alopecia in dermal papilla cells of balding human scalps, integrating published information and analysis of molecular interactions, without reporting new clinical results.

This study observed that testosterone metabolism and androgen receptor localization differ significantly across body sites, with beard hair follicles showing distinct characteristics compared to occipital scalp hair follicles.

In this study, researchers successfully established immortalized human frontal and occipital scalp dermal papilla cell lines from androgenetic alopecia patients, observing distinct gene expression, androgen receptor levels, and hair follicle growth effects between these regions, which may help advance hair loss research and therapeutic development.

The study found that silencing the gene p16INK4a in dermal papilla cells promotes their growth and aggregative behavior, suggesting a potential therapeutic target for androgenetic alopecia.

The woman's symptoms and tests suggest her adrenal glands are producing too many male hormones.

Androgens can cause hair growth in some areas and hair loss on the scalp.

This case study reports a 72-year-old woman developed male-pattern baldness after self-medicating with a high-content androgenic supplement for over 30 years.

This study identified several genes regulated by dihydrotestosterone in an SV40T-transformed human dermal papilla cell line, which may play a role in androgen-mediated hair growth regulation.

This study found that men with early-onset androgenetic alopecia had larger prostate volumes and lower urinary flow rates compared to those without the condition, suggesting a potential link between AGA and urinary symptoms.

Hair growth phase in mice weakens certain immune responses.

AMP-303 injections can increase hair growth in androgenetic alopecia with minimal side effects.

In this study, DHT inhibited hair regrowth and promoted hair follicle miniaturization in mice, with skin-resident myeloid cells enhancing their interaction with hair follicular cells, especially in females.

This study demonstrates that human skin is capable of steroid hormone synthesis, but its role in androgenic skin disorders like acne and alopecia is yet to be clarified.

Allergic contact dermatitis may promote hair growth by activating hair follicle stem cells.

In this study, subcutaneous injections of murine epidermal growth factor in marsupial pouch young inhibited the formation of hair follicles and associated structures, altering normal follicle development.
