This study found that anagen hair follicles can quickly regenerate after radiation damage by forming new progenitor cells outside the bulge, bypassing the need for telogen entry.

In this study, EREG promoted hair growth by activating specific receptors in cell and animal models, indicating it may be a potential treatment for hair loss.

Hormones cause hair loss by affecting cell growth and weakening cell attraction.

This study found that sebum in sebaceous glands is produced from cell populations derived from peripheral progenitor cells, similarly to hair growth, without direct involvement from other peripheral cells.

This commentary discusses the mechanisms of progression and potential regrowth in androgenetic alopecia, indicating that the initiation of anagen in kenogen follicles is more critical for hair density improvement than reversing follicle miniaturization.

This article proposes three mechanisms by which dihydrotestosterone may contribute to baldness but reports no new research findings.

The study found that exogenous decorin administration accelerated the anagen phase and delayed the catagen transition, suggesting it may act as a positive regulator of the hair cycle.

This study suggests that damaged anagen hair follicles have the capability to repair themselves and resume growth by mobilizing extra-bulge epithelial cells, particularly after injuries like chemotherapy and radiotherapy.

This study found that garlic exosomes induced hair growth in rats by increasing anagen follicle counts and activating multiple signaling pathways, including Wnt-1, β-catenin, and TGF-β1.

This study found that patients with androgenetic alopecia experienced more severe symptoms than those with alopecia areata, influencing their quality of life differently based on various patient characteristics.

This case report describes a young woman with an adrenal oncocytic tumor of uncertain malignant potential, highlighting the need for ongoing surveillance due to possible malignancy.

This study confirms previous observations that benign lipogenic lesions may contain eccrine/apocrine glandular components, potentially due to adipocytic proliferation entrapping glandular structures.

In this study, Cyanidin 3-O-arabinoside was found to protect against DHT-induced dermal papilla cell senescence and mitochondrial dysfunction in androgenetic alopecia, restoring hair growth in mouse models.

This study identified core genes and pathways involved in androgenetic alopecia, finding that genes related to hair follicle development are down-regulated, while those linked to immune responses are up-regulated, highlighting potential therapeutic targets.

In this case study, a 44-year-old woman with an adrenal adenoma secreting both cortisol and androgens developed Cushing syndrome and significant virilization, but experienced major symptom improvement following surgical removal of the benign tumor.

This study reports that Korean adolescents with androgenetic alopecia tend to have milder symptoms than adults and a higher prevalence of family history of alopecia.

In this study, researchers found that while both beard and scalp dermal papilla cells release similar autocrine growth factors, only beard cells increased production and response with testosterone, suggesting these factors enhance androgen-induced hair growth.

This study observed that androgen levels rise with pubic hair development in Tanner stages, differing by sex and age, with DHEA showing a significant prepubertal increase especially in precocious adrenarche.

This case report describes a girl with familial adenomatous polyposis who exhibited heterosexual precocious puberty due to an adrenal tumor secreting cortisol and androgens; after her adrenalectomy, her hormone levels normalized and symptoms improved, illustrating the link between genetic syndromes and endocrine disorders.

ROS may affect hair loss related to hormones.

This article reviews the aging process of sebaceous glands, highlighting the role of intrinsic and extrinsic factors on their degradation and reporting no new clinical findings.

This case report describes a 63-year-old woman with hyperandrogenism due to an ectopic adrenal gland adenoma on the ovaries, successfully treated with bilateral salpingo-oophorectomy.

This study observed that during the rat hair cycle, DNA synthesis in dermal cells peaks during a specific growth stage, suggesting a coordinated metabolic activity with potential implications for alopecia areata research.

This study found that local androgen biosynthesis and metabolism in human sebaceous glands play a crucial role in sebum synthesis and secretion.

This review examines a study showing that the balding scalp in men with androgenetic alopecia retains stem cells but lacks certain progenitor cells, suggesting new targets for future therapies; it reports no clinical results.

This study suggests that the paradoxical effects of androgens on hair growth are due to differential gene expression in hair follicles, possibly established during embryogenesis.

Certain enzymes react strongly with some hormones in rat skin during hair growth, mainly in sebaceous glands and hair sheaths.

In this study, researchers developed a method to automatically detect androgen receptor nuclear translocation in dermal papilla cells using fluorescence markers and image analysis, finding that the receptor's nuclear signal peaks about 20 minutes after DHT exposure.
