This study observed that two patients treated with interferon α-2b and ribavirin for chronic hepatitis C experienced complete and reversible straightening of their natural curly hair, which recurred with treatment resumption.

Iron deficiency is not a significant cause of hair loss in women.

This study found that male cancer patients had a higher risk of severe illness and death from COVID-19 compared to female patients.

This review discusses the potential link between direct oral anticoagulants and hair loss, suggesting DOACs may not be a suitable alternative for patients with alopecia from traditional anticoagulants; however, no clinical results are reported.

This review discusses the pathophysiology, genetics, and management of nonclassic congenital adrenal hyperplasia, noting subfertility and hormonal issues without providing new clinical results.

This report reviews familial cases of aplasia cutis of the scalp, noting large irregular defects at the vertex or anterior along the sagittal suture in six families.

This review examines the molecular mechanisms of the circadian clock and its effects on cardiovascular functions, proposing a novel non-invasive method using hair follicle cells to assess circadian regulation in humans, but reports no new clinical results.

This review discusses the potential role of androgen receptor CAG repeat polymorphism testing in hypogonadism management for both sexes, but its clinical utility remains unclear and requires further investigation.

This study found that early life stress significantly affects hedonic sensitivity to high-palatable food by altering gonadal hormones in prenatally-stressed male and female rats, with sex-dependent changes in reward-related behaviors and neurochemistry.

This study examined children with trichotillomania using a set of specific questions to better understand the condition and aid clinicians who may be unfamiliar with it.

This review discusses the potential of 4-azasteroids as 5α-reductase inhibitors for treating hirsutism, reporting their promising effects in animal studies but noting no clinical trials have been conducted yet.

Minoxidil reduces lysine hydroxylase in skin cells.

This review discusses the demographic, dermatologic, clinical, and psychodynamic aspects of trichotillomania, exploring its potential link to anxiety but reports no new clinical findings.

In this study, intradermal injections of autologous platelet-rich fibrin matrix significantly increased hair density in patients with androgenetic alopecia at 2 and 3 months after initial treatment.

This study evaluated Tridax procumbens extracts for their in-vitro alpha amylase inhibitory activity compared to standard antidiabetic agents, suggesting potential benefits for diabetes management.

This commentary reviews the controversial use of mesotherapy for androgenetic alopecia and emphasizes the need for documented evidence, without reporting new clinical results.

In this study, the authors reported that among patients with androgenetic alopecia, treatment with minoxidil 5% lotion combined with PRP and microneedling resulted in better hair growth and higher satisfaction compared to other treatment groups.

This study found that the growth of hair ice on dead wood requires the biological activity of a winter-active fungus, specifically Exidiopsis effusa, which shapes and stabilizes the ice structures.

This case report describes a woman who experienced diffuse hair loss both after stopping oral contraceptives and after childbirth, suggesting a similar pathogenesis in these situations.

This study found that millimolar concentrations of minoxidil in the skin induced VEGF production through HIF-1 stabilization by inhibiting PHD-2, implying a molecular mechanism for hair growth promotion.

This study found that two new progesterone derivatives showed higher antiandrogenic effects and 5α-reductase inhibition than finasteride in hamsters, particularly reducing seminal vesicle weight and flank organ size.

This study investigated the use of dissolving microneedle patches to improve the skin-lightening effects of alpha-arbutin and resveratrol, finding that the patches enhanced intradermal delivery and slightly decreased the melanin index without affecting skin hydration or causing irritation over 24 hours.

This review discusses the physiology and potential hormonal mechanisms involved in female pattern hair loss, as well as the current hormonal and hormone-modifying treatments available, but reports no new research findings.

This study found that the protein CCN2 in dermal papilla cells is a physiologically relevant suppressor of hair follicle formation by destabilizing β-catenin, which may help maintain stem cell quiescence.

In this study, heavy nighttime physical exercise delayed the circadian phase of clock gene expression by 2 to 4 hours in a professional fighter, suggesting potential implications for managing circadian disorders.

This study found that early onset androgenetic alopecia in young Asian Indian Gujarati men is independently associated with an increased risk of coronary artery disease.

This review discusses the potential of adipose-derived stem cells for treating vitiligo, hair loss, and chronic wound healing, but reports no new clinical results and suggests the need for further investigation.

This study reported that women with Polycystic Ovary Syndrome have higher rates of clinically significant insomnia and excessive daytime sleepiness than women without the condition, highlighting the need for sleep disorder screening in this population.

Some chemicals absorbed through the skin can cause serious health problems.

This review discusses the management of hirsutism in women, highlighting promising treatments like metformin for polycystic ovarian syndrome, and emphasizes the importance of understanding hair growth cycles and realistic treatment expectations; it reports no new clinical results.
