This systematic review indicates that a platelet-rich plasma concentration of 1.0 × 10^6 plt/μL may be optimal for tissue regeneration due to sufficient nutrition supply and effective growth factor diffusion in vivo.

This study identified new geometric and mechanical parameters for curly and kinky/coily hair, which may inform more effective personal care products tailored to these hair types.

This study observed that carbon paste electrodes catalyze the electrooxidation of minoxidil more efficiently than other electrode types, with a detection limit of approximately 20 ng mL^-1.

This study suggests a decision tree using in vitro metabolic clearance to identify early drug candidates likely to experience nonlinear pharmacokinetics due to intestinal CYP3A-related metabolism.

Blocking IL-1 could help treat some hair loss conditions; alopecia affects liver detox systems; spironolactone is better than finasteride for female hair growth; focusing on the catagen hair phase could lead to new alopecia treatments.

This study describes the development of the BASP classification system, providing a universal and systematic approach for classifying pattern hair loss in both men and women.

This study presents a new classification of adult human scalp hair patterns based on high-resolution photographs, which may assist hair restoration surgeons and dermatologists in determining appropriate punch size for follicular unit extraction.

This study found that elevated free testosterone levels may reduce body fat and increase bone density in males, but also raise the risk of prostate cancer, hair loss, and benign prostate hyperplasia.

This article reviews various aspects of growth factor research, highlighting their role in treatments and emphasizing the need for further clinical trials to validate their efficacy in biomedical applications.

This case study reports a rare instance of mucinous cystadenoma causing severe virilization in a postmenopausal woman, highlighting a possible link with rapidly progressive hyperandrogenism.

Hair straightening methods have advanced to improve effectiveness and reduce damage, but still rely on heat and chemicals.

This article is a letter discussing variations in male sex hormone levels among different pattern subtypes of androgenetic alopecia and does not present new research results.

This study observed that extracellular matrix scaffold membranes performed less effectively in wound healing for aged mice compared to younger ones, with senescent SPP1+ macrophages potentially hindering epidermal and fibroblast repair abilities.

This study introduced the BASP classification, a new system for categorizing pattern hair loss in both men and women, and applied it to analyze 2213 Korean subjects.

This scoping review evaluates the connection between hypoxia and declining sex hormonal signaling in middle-aged individuals, proposing a "middle-aging hypovascularity hypoxia hypothesis" as a potential mechanism influencing age-related diseases, with implications for developing strategies to maintain healthspan.

This study found that phenolic compounds from Quercus acutissima, particularly casuarinin, showed strong antioxidative, anti-inflammatory, and antiacne effects in mouse macrophage cells, suggesting potential therapeutic candidates for acne.

This review discusses the causes and recommended clinical investigations for postmenopausal hyperandrogenism, highlighting the role of androgen excess in symptoms like hirsutism and its association with metabolic disorders.

In a comparative genomic study, researchers observed significant genetic differences among the three chemical races of the alga Botryococcus braunii, leading them to propose reclassifying these races as distinct species based on their unique genomic characteristics.

This study suggests that coexisting LSS and TSPEAR variants might contribute to a complex phenotype of congenital hypotrichosis and ectodermal abnormalities in a child, and highlights the need for cautious interpretation of genotype-phenotype links and the potential value of broader genetic testing.

This study demonstrated that high oral doses of finasteride caused external genital abnormalities in male rhesus monkey fetuses, but intravenous doses did not lead to abnormalities.

This study found that finasteride at 1 mg/day was the most effective dose for treating male pattern hair loss, with similar efficacy to 5 mg/day and better results than lower doses.

In this study, researchers observed that mechanosensory neurons initially develop similar morphologies across different skin regions but diverge post-natally, adapting to the type of skin they innervate, with bone morphogenetic protein signaling crucial for forming Meissner corpuscles in glabrous skin.

This study investigated differences in gene expression in the mammary glands of SLICK and wild-type Holstein cattle, finding limited differences overall but identifying enriched pathways related to arachidonic acid metabolism and oxytocin production, which merit further exploration.

This study found that LY320236 is a competitive inhibitor of type I and a non-competitive inhibitor of type II steroid 5alpha-reductase, indicating its potential as a dual inhibitor with differing modes of activity.

MK-386 and finasteride together effectively reduce DHT levels, potentially treating acne and male pattern baldness.

This study reported that women with polycystic ovary syndrome had a higher prevalence of impaired glucose tolerance and type 2 diabetes, with variations influenced by ethnicity and obesity.

This study found that in naturally curved human scalp hairs, distinct arrangements of cell types on either side of the hair fiber contribute to its curvature.

This study found that the SRD5A2 A49T A variant is associated with an increased risk of prostate cancer, lower circulating 3α‐diolG levels, and a decreased risk of baldness.

This study mapped monilethrix, a hereditary hair and nail disorder, to the type II keratin cluster on chromosome 12q, marking the first primary human hair disorder localization and implicating defects in "hard" keratins.

This study found that overexpression of parathyroid hormone-related protein in mice resulted in 30–40% shorter hair due to premature transition into the catagen phase of the hair cycle.
