Stopping finasteride for male pattern hair loss changes neuroactive steroid levels in the brain and blood.

This study found that finasteride treatment for androgenic alopecia significantly increased certain plasma polyamine levels over three years, but did not alter polyamine levels in urine.

This article discusses the testosterone and estradiol levels in men, examining their roles and suggesting the need for better understanding to differentiate between normal and abnormal levels related to androgen deficiency symptoms, without reporting new clinical results.

Accurate method measures finasteride levels in human plasma using gas chromatography-mass spectrometry.

This study found that platelet-rich plasma therapy significantly promoted hair growth in androgenetic alopecia model mice by enhancing autophagy, with effects similar to rapamycin treatment.

In this study, significant elevations of DHA and testosterone were associated with pubic hair development and voice changes in boys during puberty.

This study observed that adding simvastatin to ongoing metformin treatment reduced certain androgen levels in women with non-classic congenital adrenal hyperplasia and abnormal glucose metabolism, suggesting a potential therapeutic benefit.

In this study, oral broccoli sprouts intake did not affect plasma androgen levels in males, while alfalfa sprouts intake increased testosterone and DHT levels, which may help prevent male late onset hypogonadism.

In this study, PRP therapy showed effectiveness in treating mild to moderate alopecia areata in patients with normal antithyroid antibodies, while those with severe forms or elevated antibodies did not experience significant benefits.

This study found that intraovarian PRP treatment in women with low ovarian reserve was associated with significant increases in serum AMH levels in some patients, typically within four weeks.

In this study, high-dose dutasteride significantly reduced several core symptoms of PMDD compared to placebo, supporting the role of neurosteroids in this condition.

This study found that platelet-rich plasma significantly increased hair count, density, and the percentage of anagen hairs in patients with androgenetic alopecia, but these improvements did not correlate with platelet or growth factor levels.

The researchers reported that freeze-dried collagen-activated platelet-rich plasma increased transforming growth factor-β1 levels compared to non freeze-dried PRP with collagen, suggesting a potential benefit for tissue regeneration.

This letter raises questions for the authors of a recent study on platelet-rich plasma for androgenetic alopecia, without presenting new clinical results.

In this study, terbinafine reached high concentrations in stratum corneum and sebum after oral administration, with drug levels remaining above fungicidal concentrations for over three weeks.

Lower testosterone levels in men may be linked to a higher risk of severe coronary artery disease.

This study found that plasma-activated water significantly improved wound healing in diabetic rats compared to both atmospheric pressure cold plasma and conventional dressings.

This study concluded that combining platelet-rich plasma with low-level light therapy was more effective than combining it with minoxidil or using light therapy alone for treating androgenetic alopecia.

This study found that dietary selenium levels above 5 ppm can lead to selenosis in pigs, with white-haired pigs showing alopecia sooner than dark-haired pigs.

This case report observed that a selenium-deficient diet in a child with propionic acidaemia led to macrocytosis and hair abnormalities, which improved with selenium supplementation.

In this study, long-term normalization of testosterone levels in postmenopausal women with hyperandrogenism did not improve body mass index, glucose, or lipid metabolism.

This study found that salivary testosterone levels were significantly lower in oligospermic and azoospermic men compared to normal men, suggesting its potential use in assessing male androgen status.

This study found that supplementing dog food with zinc methionyl glycinate at 160 ppm improved hair growth rate, zinc levels in plasma and hair, and hair condition more than lower doses or sulfate form.

This study observed that female patients with chronic telogen effluvium had significantly lower levels of total thiol, thiol-disulphide, and disulphide compared to healthy controls, indicating a disruption in oxidative stress balance.

This study found that men with androgenetic alopecia had significantly lower levels of sex hormone binding globulin and higher salivary testosterone compared to controls, while plasma testosterone levels did not differ.

This study presents a method using liquid chromatography tandem mass spectrometry to quantify biotin in plasma and serum, and explores how high biotin intake can interfere with diagnostic immunoassays that utilize biotin-streptavidin technology, potentially leading to misdiagnosis of endocrine disorders.

This study observed that the intestinal absorption of selenium varies depending on its chemical form, with selenomethionine being absorbed efficiently and selenium as selenodiglutathione or selenodicysteine being absorbed faster than selenite.

This review discusses the use of platelet-rich plasma for various dermatological conditions and highlights the need for more research to standardize its protocols and understand its biological mechanisms.

This expert group provided recommendations for preparing and using platelet-rich plasma in treating androgenetic alopecia, suggesting a manual double-spin method and specific dosing, although further studies on injectable platelet-rich fibrin are needed.
