660-690 / 1000+ resultsresearch Hair cortisol analysis: An update on methodological considerations and clinical applications
Hair cortisol analysis can help diagnose stress-related conditions but needs more refinement for widespread use.
research Biology of the Hair Follicle: The Basics
The document concludes that understanding hair follicle biology can lead to better hair loss treatments.
research Alopecia areata: a review of disease pathogenesis
Alopecia areata is likely an autoimmune disease with unclear triggers, involving various immune cells and molecules, and currently has no cure.
research Alopecia Areata: A tissue specific autoimmune disease of the hair follicle
Alopecia areata is an autoimmune condition causing hair loss due to the immune system attacking hair follicles, often influenced by genetics and stress.
research Is there a ‘gut–brain–skin axis’?
Probiotics may help reduce stress-related skin issues and improve hair growth.
research Histopathology of alopecia: a clinicopathological approach to diagnosis
The conclusion is that accurate diagnosis of different types of hair loss requires good teamwork between skin doctors and lab experts.
research The Pathogenesis of Primary Cicatricial Alopecias
The document concludes that more research is needed to better understand and treat primary cicatricial alopecias, and suggests a possible reclassification based on molecular pathways.
research Maternal Influence on Child HPA Axis: A Prospective Study of Cortisol Levels in Hair
Maternal stress during pregnancy affects a child's stress levels.
research Histopathology of non-scarring alopecia
The document describes how to tell different types of non-scarring hair loss apart by looking at hair and scalp tissue under a microscope.
research Biology of the wool follicle: an excursion into a unique tissue interaction system waiting to be re‐discovered
The article concludes that the wool follicle is a valuable model for studying tissue interactions and has potential for genetic improvements in wool production.
research Local circadian clock gates cell cycle progression of transient amplifying cells during regenerative hair cycling
Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.
research Integrative and Mechanistic Approach to the Hair Growth Cycle and Hair Loss
A holistic approach is needed to effectively address hair loss by understanding and influencing the hair growth cycle.
research Neural Mechanisms of Hair Growth Control
Nerves and chemicals in the body can affect hair growth and loss.
research Hormones and the pilosebaceous unit
Hormones significantly affect hair and oil gland function in the skin, and more research is needed on skin-related hormone disorders.
research ADRENOCORTICAL FUNCTION IN PUBERTY Serum ACTH, Cortisol and Dehydroepiandrosterone in Girls and Boys
Girls have higher DHEA levels earlier in puberty than boys, indicating earlier development.
research Alopecia: possible causes and treatments, particularly in captive nonhuman primates.
Alopecia in captive primates can be caused by many factors, so thorough testing is needed before blaming stress.
research In situ tensile deformation characterization of human hair with atomic force microscopy
AFM helped show how hair changes under tension and the effects of damage and conditioner.
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 CHRONIC TELOGEN EFFLUVIUM
Chronic Telogen Effluvium is a hair loss condition in middle-aged women that usually doesn't lead to complete baldness.
research Seasonal and social correlates of changes in hair, skin, and scrotal condition in vervet monkeys (Cercopithecus aethiops) of Amboseli National Park, Kenya
Vervet monkeys show physical changes like hair loss and scrotal color changes due to stress or nutrition issues.
research Variables affecting the potential efficacy of PRP in providing chronic pain relief
Standardizing PRP preparation and application could improve its effectiveness for chronic pain relief.
research Development, Characterization, and Use of a Fetal Skin Cell Bank for Tissue Engineering in Wound Healing
Fetal skin cells from a cell bank heal wounds faster and with less scarring than adult cells.

Some parents have a mild form of congenital adrenal hyperplasia without symptoms, and they usually don't need treatment.
research The itchy scalp - scratching for an explanation
Scalp itching is common and hard to diagnose due to the complex nerve structure of the scalp.
research Human Hair Follicle and Epidermal Melanocytes Exhibit Striking Differences in Their Aging Profile which Involves Catalase
Hair follicle cells age faster and lose pigment due to less catalase, causing hair to turn gray.
research Coat condition, housing condition and measurement of faecal cortisol metabolites - a non-invasive study about alopecia in captive rhesus macaques (Macaca mulatta)
Alopecia in captive rhesus macaques is affected by season, sex, age, housing, and stress, with complex links between stress hormones and hair loss.
