This study found that STAT3 signaling is essential for initiating the hair growth phase but not involved in hair follicle development during the fetal period.

This study reported that transgenic mice with targeted TNF alpha expression in keratinocytes showed impaired weight gain, retarded hair growth, and skin changes, leading to cachexia and necrosis.

In this study using human cell cultures, type 1 5α-reductase was found to vary in both protein heterogeneity and expression levels across different types of skin cells.

This study concluded that high-dose oral therapy with L-cystine, gelatin, and vitamin A significantly improved hair growth indicators in patients with diffuse hair loss, with no systemic side effects observed.

This report discusses a teenager with blistering of localized epidermolysis bullosa simplex—Weber Cockayne type, recommending referral to dermatology, and includes no new clinical trials or broader conclusions.

This study introduced a new technique, 2Phatal, enabling precise apoptotic cell ablation in living animals, revealing unique cell-type differences in apoptosis-related dynamics.

This study found that modified laparoscopic sleeve gastrectomy in patients with type 2 diabetes and obesity reduced ghrelin levels, improved glycemic and insulin levels, and resulted in significant weight loss.

This clinical trial found that combining 678 nm helmet-type low-level laser therapy with topical minoxidil 5% significantly increased hair density and patient satisfaction in men with androgenetic alopecia, compared to using minoxidil alone. Both treatments were well tolerated.

This study reports that hypomorphic alleles of the Ass1 gene in mice resemble human CTLN1, providing a potential model for preclinical studies and indicating that standard treatments for CTLN1 can rescue phenotypes.

This study found that tofacitinib led to ≥50% hair regrowth in eight out of twelve patients with moderate to severe alopecia areata, suggesting a potential benefit for using JAK inhibitors in treating this condition.

This study reported that 5 alpha-reductase type 2 is the predominant enzyme in pubic skin fibroblasts across normal men, women, and hirsute patients, suggesting potential treatment options for idiopathic hirsutism.

This study suggests that targeting olfactory receptors in the lung epithelium might help treat odorant-induced asthma in cases without type 2 inflammation, as these receptors could play a role in airway sensitivity to smells.

Mouse tail skin has different keratinization near hair follicles and scales.

This case report describes two patients with trichothiodystrophy who exhibited a different pattern of hair protein composition changes, suggesting a subgroup of TTD characterized by partial loss of high-sulfur proteins without significant alteration in their amino acid composition.

This article discusses the factors involved in optimizing laser hair removal, emphasizing patient selection, laser safety, and understanding laser–tissue interactions, but presents no new clinical findings.

This study found that human hair can be classified into eight main types based on objective measurements of shape, rather than ethnic categories, enhancing the understanding of hair diversity globally.

This study found that disulfide bonds in keratin increase its strength and toughness, with some loss of α-helical structure under load, highlighting their role in trichocyte α-keratin's mechanical properties.

This study identified upregulation of genes linked to fibroproliferative disorders, such as platelet-derived growth factor and collagen genes, in patients with central centrifugal cicatricial alopecia, suggesting potential therapeutic targets.

This study found that transgenic mice expressing HPV E6/E7 in the outer root sheath experience continuous hair follicle cycling due to delayed catagen entrance and insensitivity to telogen resting signals.

This article reviews key developments in pediatric dermatology for 2017, including consensus recommendations, novel genetic findings, and treatment insights for conditions like psoriasis and vascular malformations, without providing new clinical trial results.

More research is needed to understand hair and scalp disorders in children with skin of color.

This study reviews the biology and cosmetic treatment of hair, emphasizing future advancements in safer, more effective procedures to meet consumer needs for hair care.

This study estimates the total cost of evaluating and treating polycystic ovary syndrome in reproductive-aged women in the United States to be $4.36 billion, suggesting more liberal screening could be beneficial.

In this study, researchers found that hair follicle orientation in Fz6 −/− mice is disrupted and that hair may reorient itself over time through a self-organized process.

This study found that daily use of 1% pyrithione zinc shampoo modestly improved hair growth over 26 weeks, although these effects were less than those of 5% minoxidil.

This review discusses the range and causes of adipose tissue diseases, emphasizing genetic and acquired forms of lipodystrophy, but it reports no new clinical results.

This study highlights the loss of hair-type keratin genes in cetaceans compared to terrestrial mammals, suggesting a potential adaptive role linked to their hairless phenotype and habitat changes.

This review discusses the anatomy, evaluation, surgical methods, and nonsurgical options for forehead lifting, but it reports no new clinical results.

This article reviews common causes of hair loss, noting that a well-directed history and examination are often sufficient for diagnosis, and reports no new clinical findings.
