In this study, UVB irradiation of organ-cultured human anagen hair follicles in vitro reduced hair elongation and increased cell death, affecting hair growth and regulatory processes.

This case study reported that absence of alopecia does not reliably predict responsiveness to vitamin D treatment in Vitamin D-dependent rickets type II, as demonstrated by a patient with normal hair growth who showed extreme resistance.

In this study, lipid peroxides were found to induce apoptosis in hair follicle cells and advance the catagen phase in mice, suggesting a potential mechanism for alopecia development.

In this study, mice exposed to prolonged space conditions demonstrated skin atrophy, altered hair follicle cycles, and significant changes in the gene expression associated with skin muscle health.

This study found that overexpressing human Bcl-2 in mice protected epidermal keratinocytes from UVB-induced apoptosis but unexpectedly increased apoptosis during hair follicle regression and chemotherapy.

This review discusses the effects of oestrogen on skin ageing and highlights the need for large-scale clinical trials to evaluate postmenopausal oestrogen use, reporting no new findings.

This review discusses polycystic ovary syndrome treatments, focusing on the potential benefits and safety of herbs and phytochemicals, and reports no new clinical results.

This article reviews the role of vasoactive intestinal peptide in maintaining immune privilege in hair follicles and does not report new findings; the authors propose it as essential for immune homeostasis in alopecia areata.

This study found that cyclosporine A treatment at 5 mg/kg/day may reduce inflammation and promote gland regeneration in dogs with sebaceous adenitis, though symptoms returned when treatment stopped.

This study found that ultraviolet radiation negatively affects hair follicle functions in human scalp skin, and caffeine application may provide some protective effects against this damage.

This study provides evidence that Cyclosporine A inhibits catagen development in human hair follicles, suggesting different underlying mechanisms from those observed in rodent studies.

This study observed that selectively activating activin in the epidermis of mice enhanced reepithelialization during wound healing without altering the quality of the healed wound.

This study concluded that ablative fractional lasers may induce hair regrowth in mice by activating the Wnt/β-catenin pathway.

This study found that l-carnitine stimulated hair growth in vitro by promoting proliferation and reducing apoptosis in human scalp hair follicles, suggesting potential as a treatment for hair loss.

In this study, topical application of the SCD1 inhibitor XEN103 significantly reduced sebaceous gland size and number in mouse skin, suggesting potential local therapeutic effects for acne treatment without systemic side effects.

In this study, oral finasteride treatment for four weeks reduced the weight of the corpus cavernosum in rats but did not significantly affect erectile function.

In this study, a synthetic antagonist of the p75 neurotrophin receptor was found to significantly inhibit hair follicle regression in murine skin cultures, suggesting a potential role in treating hair disorders characterized by premature catagen entry.

This study found that low-level laser therapy may have promising effects on hair regrowth in dogs with noninflammatory alopecia, with most animals showing improvement after treatment.

This practical guide introduces methods to study human dermal white adipose tissue but does not report new clinical results, emphasizing available techniques and staining protocols.

This study found that deleting the Hes1 gene disrupts hair regeneration by delaying anagen initiation and shortening the anagen phase, suggesting it's crucial for maintaining hair cycle homeostasis.

This study found that inhibiting EGFR signaling in mice can prevent alopecia caused by cyclophosphamide treatment, highlighting its potential role in managing chemotherapy-induced hair loss.

This study reports that the novel small molecule IM176OUT05, by modifying stem cell metabolism, promoted hair regrowth and increased hair follicle numbers in mice.

This study found that the proteins GDNF, NTN, GFRα-1, GFRα-2, and c-Ret are differentially expressed during various stages of the human hair follicle cycle, with potential implications for hair biology.

This study concluded that administering dutasteride for more than 8 weeks in rats could lead to irreversible erectile dysfunction, even after stopping the medication.

This study found that the synthetic thyroid hormone receptor modulator KB2115 significantly prolonged the growth phase of human hair follicles in culture without altering mitochondrial activity, suggesting potential as a safer hair loss treatment compared to traditional thyroid hormones.

In this study, topical 5% roxithromycin was effective in restoring hair growth in about half of individuals with androgenetic alopecia without causing adverse effects.

Cedrol cream is more effective and safe for promoting hair growth than traditional treatments.

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 article discusses the potential for topical caffeine as a natural alternative for treating androgenetic alopecia due to its ability to penetrate skin, but it reports no new clinical findings.

This article describes the immunofluorescence tomography method to achieve high-resolution 3-D reconstruction of epithelial tissues and reports no clinical results.
