research Alopecia Areata: Hyperactivity of the Hypothalamic–Pituitary–Adrenal Axis Is a Myth?
The study found no significant difference in stress hormone levels between people with alopecia areata and healthy individuals, suggesting that the disease is not caused by an overactive stress response system.
research Sequential Estrogen-Progestin Addition to Gonadotropin-Releasing Hormone Agonist Suppression for the Chronic Treatment of Ovarian Hyperandrogenism: A Pilot Study
The treatment effectively reduced hair growth and was safe for patients with PCOS, but it needs better bleeding control.
research Reversal of the Hair Loss Phenotype by Modulating the Estradiol-ANGPT2 Axis in the Mouse Model of Female Pattern Hair Loss
Adjusting estradiol-ANGPT2 levels can promote hair growth in female pattern hair loss.
research Effect of Constant-Release Melatonin Implants and Prolonged Exposure to a Long Day Photoperiod on Prolactin Secretion and Hair Growth in Mouflon (Ovis Gmelini Musimon)
Melatonin implants and long daylight hours alter the timing of hormone release and hair growth in mouflon sheep.
research Corticosterone Inhibits GAS6 to Govern Hair Follicle Stem-Cell Quiescence
Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.
research Frontiers in the Neuroendocrine Controls of Hair Growth
Hair growth and health are influenced by stress and hormones.
research Hair Growth Inhibition by Psychoemotional Stress: A Mouse Model for Neural Mechanisms in Hair Growth Control
Stress can stop hair growth in mice, and treatments can reverse this effect.
research Physiology of the Hypothalamic Pituitary Gonadal Axis in the Male
The document explains how the male reproductive system works, its role in making testosterone, and how conditions like obesity can disrupt it, leading to low testosterone and fertility issues.
research Differential Relationships Between Chronic Hormone Profiles in Pregnancy and Maternal Investment in Rhesus Monkey Mothers With Hair Loss in the Neonatal Period
Monkeys with hair loss during pregnancy showed higher stress hormone levels and invested differently in their offspring.
research Indications for a Brain-Hair Follicle Axis: Inhibition of Keratinocyte Proliferation and Up-Regulation of Keratinocyte Apoptosis in Telogen Hair Follicles by Stress and Substance P
Stress can cause hair loss by negatively affecting hair follicles and this effect might be reversed with specific treatments.
research Gender-Affirming Hormone Therapy for Transgender Females
Hormone therapy for transgender females increases the risk of blood clots and requires careful dosing, monitoring, and lifelong management.
research Clinical and Phototrichogrammatic Evaluation of Estradiol Replacement Therapy on Hair Growth in Postmenopausal Japanese Women with Female Pattern Hair Loss: A Pilot Study
Hormone replacement therapy may improve hair growth in the frontal hairline of postmenopausal women with hair loss.
research Consequences of Steroid-5α-Reductase Deficiency and Inhibition in Vertebrates
Lack or blocking of SRD5a, a key component in hormone creation, can lead to conditions like pseudohermaphrodism and affect hair growth, bone mass, muscle strength, and reproductive health. More research is needed on its regulation from fertilization to adulthood.
research Cross-Sex Hormone Therapy in Trans Persons Is Safe and Effective at Short-Term Follow-Up: Results from the European Network for the Investigation of Gender Incongruence
Hormone therapy for trans individuals is effective and generally safe in the short term.
research Alleviation of Androgenetic Alopecia with Aqueous Paeonia Lactiflora and Poria Cocos Extract Intake Through Suppressing the Steroid Hormone and Inflammatory Pathway
Paeonia lactiflora and Poria cocos extracts can potentially increase hair growth and reduce hair loss symptoms by lowering testosterone and inflammation levels.
research Downstream Molecular Responses to Volatile Signaling in Roots
Plant roots respond to fungus smells by possibly using certain proteins and a plant hormone to change root growth, but more research is needed.
research Androgenic Alopecia: Cross-Talk Between Cell Signal Transduction Pathways
Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
research Preponderance of Serum and Intra-Hepatic 5α-Dihydrotestosterone in Males with Hepatocellular Carcinoma Despite Low Circulating Androgen Levels
Men with liver cancer have higher levels of a specific testosterone byproduct in their liver and blood, despite overall lower male hormone levels.
research Expression of Hypothalamic-Pituitary-Thyroid Axis Related Genes in Human Skin
Thyroid-related genes are active in skin cells and may affect autoimmune conditions.
research Hair Follicle as a Target of Stress Hormones and Autoimmune Reactions
Stress hormones and autoimmune reactions can cause hair loss.
research Thyroid Hormone Action in Epidermal Development and Homeostasis and Its Implications in the Pathophysiology of the Skin
Thyroid hormones are important for skin health and changes in them can affect conditions like hair loss and eczema.
research Androgen Profiling by Liquid Chromatography–Tandem Mass Spectrometry in Healthy Normal-Weight Ovulatory and Anovulatory Late Adolescent and Young Women
The research found that anovulatory young women have higher androgen and hormone levels than those who ovulate, suggesting immature hormonal regulation rather than a specific condition.
