In this study, a hair tonic containing fragrant pandan leaf extract and virgin coconut oil was formulated and evaluated, with most variations demonstrating physical stability except for one formulation, which showed instability in the specific gravity test.

This study reported the development of a novel and reliable liquid chromatographic method to measure testosterone and epitestosterone in human urine, offering sensitive detection for doping control.

This review aims to help medical practitioners understand inferential statistical methods to critically evaluate clinical trial design and analyses, but it doesn’t present new research findings.

Men with early balding should be checked for metabolic syndrome, as there's a link between the two.

This study found that testosterone concentrations in hair samples were moderately stable over three months, with cosmetic treatments like coloring increasing testosterone levels, while natural hair color in untreated hair did not affect testosterone measurements.

This article provides a multiple-choice quiz based on dermatology information but shares no new research findings.

This dissertation reported that the loss of Ovol2 impairs hair follicle regeneration and wound repair in mice, highlighting its role in regulating directional migration of epithelial cells.

This study found that testosterone therapy improved physical performance and strength in older men with low testosterone over 36 months, whether administered alone or with finasteride.

This study found a weak positive correlation between dihydrotestosterone levels and C-reactive protein in COVID-19 patients, particularly in those with low testosterone, suggesting potential inflammatory effects.

This study found that the total testosterone/dihydrotestosterone ratio correlates with a negative metabolic profile in both women with PCOS and healthy women.

This study found that measuring reproductive hormone levels in brown bear hair may effectively support non-invasive genetic sampling, though larger samples or more sensitive techniques are needed for broader application.

This study found that ion-paired solutions significantly improved the skin penetration of risedronate in hairless mice compared to risedronate alone.

This study found that in men with benign prostatic hyperplasia, a 3-month treatment with a long-acting GnRH agonist significantly reduced intraprostatic DHT and 3α-diol levels by about 90% and testosterone by about 75%.

This study found that Bokusoku extract and its compound pentagalloyl glucose inhibited testosterone metabolism and sebum synthesis, suggesting potential therapeutic use for androgen-related acne.

This study found that zebrafish and stickleback fish use similar genetic programs for tooth regeneration, despite differences in their dental structures.

This study found that testosterone and dihydrotestosterone can induce growth factors from dermal fibroblasts, promoting keratinocyte proliferation and differentiation, which may contribute to sex hormone-related acne development.

This study indicates that the normal human prostate is not a major contributor to circulating blood DHT concentrations in androgen-deficient patients receiving testosterone replacement therapy.

The guidelines advise against using testosterone and DHEA in women for most conditions due to safety and effectiveness concerns, but suggest considering testosterone for postmenopausal women with low sexual desire.

This study found that finasteride decreased plasma dihydrotestosterone levels and altered steroid metabolism, similar to the profile of male pseudohermaphrodites with inherited 5a-reductase deficiency.

Minoxidil solution helps hair regrowth in alopecia areata, with 5% being more effective.

In this study of healthy men, low levels of testosterone and dihydrotestosterone were associated with higher body mass index, fat content, and insulin resistance, but their effects on lipid and glucose metabolism were similar in quality.

This study found that untargeted hair metabolomics analysis detected significantly altered endogenous biomolecules, potentially serving as biomarkers for identifying oxidative cosmetic hair treatments like bleaching.

In this pilot randomized clinical trial, TRT combined with finasteride increased lean mass, muscle size, and bone mineral density without prostate enlargement in men with spinal cord injury, suggesting potential benefits for body composition and musculoskeletal health.

This study concluded that albumin-bound testosterone is biologically important and significantly contributes to testosterone bioavailability in women receiving spironolactone.

In this pilot study, finasteride increased testosterone/dihydrotestosterone and progesterone/dihydroprogesterone ratios in normal ovulatory women but did not alter ovulation or gonadotropin secretion.

This study found that spironolactone therapy may reduce hair width in prepubertal girls with simple hypertrichosis, though its long-term efficacy and safety remain uncertain.

This study demonstrated that CD19-CAR T cell therapy may promote structural regeneration in the skin of systemic sclerosis patients, as evidenced by histological improvements and fibroblast population changes, suggesting its potential for tissue remodeling in fibrotic diseases.

This study found that fibroblast growth factor 9, initially secreted by γδ T cells, plays a key role in modulating hair follicle regeneration in mice after skin wounds.

This study found that the prevalence of polycystic ovary syndrome was 6.5% in a minimally biased sample of Caucasian women from Spain.

In this study, five-year testosterone replacement therapy improved fasting blood sugar, HbA1c, and triglyceride levels in Japanese hypogonadal men without significantly affecting prostate-specific antigen levels.
