research Recent Progress in Understanding the Effect of Sympathetic Nerves on Hair Follicle Growth
Stress can cause hair loss by affecting nerve-related hair growth, and noradrenaline might help prevent this.
research Environment of the Anagen Follicle
The document concludes that hair follicles have a complex environment and our understanding of it is growing, but there are limitations when applying animal study findings to humans.
research Histology, Lectin Histochemistry, and Ultrastructure of Interdigital Gland in Crossbred Sheep
The interdigital gland in crossbred sheep is similar to skin and has specialized structures for secretion.
research Matricellular Proteins in the Homeostasis, Regeneration, and Aging of Skin
Special proteins are important for skin balance, healing, and aging, and affect skin stem cells.
research Immunohistochemical Localization of Fibroblast Growth Factor 18 in Hair Follicles of Healthy Beagle Dogs
FGF18 is present in beagle dog hair follicles, mainly in the inner root sheath.
research Comment on Scalp Neuropathy in Androgenetic Alopecia
Hair loss in men (androgenetic alopecia) is significantly linked to decreased scalp sensitivity, but not temperature sensitivity. More research is needed to confirm this. Comparing this hair loss to leprosy is unsupported and stigmatizing.
research Scalp Neuropathy in Androgenetic Alopecia
Scalp nerve issues are linked to hair loss in men.
research Embryology, Histology, and Physiology of the Hair Follicle
The document explains how hair follicles develop, their structure, and how they grow.
research New Histopathological Findings in Scarring Alopecias
New findings may help diagnose and understand scarring alopecia better.
research Evaluation of Morphological and Histological Changes in Transplanted Hair Follicles
Transplanted hair follicles show significant changes after FUE, needing more research.
research A Single Intradermal Injection of Autologous Adipose-Derived Stem Cells Rejuvenates Aged Skin and Sharpens Double Eyelids
Injecting a person's own fat stem cells into their skin can make it look younger and improve double eyelids for over a year.
research Histological Study of Horse Skin
Horse skin has a layered epidermis, a dermis with hair follicles, sweat and sebaceous glands, and is supplied by small arteries.
research A 43-Year-Old Woman with a Solitary, Asymptomatic Nodule on the Scalp
A woman's scalp nodule was a common, harmless pilar cyst, treated by surgical removal.
research The Eyelash Comes to the Fore: Significance in Aesthetics and Eye Protection
Eyelashes are important for looks and eye protection, and more people are treating sparse eyelashes; more research is needed to understand eyelash biology and improve treatments.
research Plain Language Summaries of Dermatological Studies
Eczema patients have a lower skin lipid to protein ratio, older and longer-staying hospital patients are more likely to get pressure ulcers, hair loss in AGA is linked to muscle degeneration, vitamin D deficiency is common in alopecia areata and linked to its severity, standard liver tests don't effectively detect fibrosis in psoriasis patients on methotrexate, and bullous pemphigoid patients have a higher death risk but combination therapy may reduce it.
research Phenobarbital
A woman experienced unusual hair loss and skin reactions after taking phenobarbital, but her hair grew back after treatment.
research Androgenetic Alopecia: Mechanisms and Progression
Androgenetic alopecia causes hair loss by shrinking hair follicles due to androgens, with the connection between the muscle and hair follicle determining if the loss is reversible.
research Faculty Opinions Recommendation of Fully Functional Hair Follicle Regeneration Through the Rearrangement of Stem Cells and Their Niches
Scientists successfully created fully functional hair follicles using bioengineering methods and stem cells.
research Describing Hair and Related Abnormalities
The document explains hair growth, hair loss types, and other hair-related terms.
research Breakthroughs in the Diagnosis and Treatment of Male and Female Pattern Hair Loss
New methods can diagnose hair loss by examining the scalp and can treat it with a mix of oral and topical medications, along with cosmetic procedures like hair transplants.
research The Genetics of Hair Shaft Disorders
The article explains the genetic causes and symptoms of various hair disorders and highlights the need for more research to find treatments.
research Inherited Disorders of the Hair
The document explains the genetic causes and characteristics of inherited hair disorders.
research Pathogenesis of Androgenetic Alopecia
Androgenetic alopecia, or hair loss, is caused by a mix of genetics, hormones, and environment, where testosterone affects hair growth and causes hair to become smaller and grow for a shorter time.
research Dermatologic Manifestations of Thyroid Disease: A Literature Review
Thyroid disease can cause skin, hair, and nail problems, and treating the thyroid condition often improves these symptoms.
research Dermal Wnt/β-Catenin Activation Tunably Controls Hair Follicle Initiation
Activating Wnt in skin cells controls the number of hair follicles by directing cell movement and fate.
research The De Novo DNA Methyltransferase DNMT3A Is Required for Epidermal Homeostasis
DNMT3A is crucial for healthy skin and hair growth.
research Mature Adipocytes Inhibit the Antimicrobial Function of Dermal Adipogenic Stem Cells: An Explanation for Impaired Cutaneous Defense in Obesity
Obesity can weaken the skin's ability to fight infections because fat cells stop and reduce the infection-fighting properties of nearby stem cells.
research Morphometric Analysis of the Human Scalp Hair Follicle: Practical Implications for the Hair Transplant Surgeon and Hair Regeneration Studies
The research provides specific measurements for hair follicles that can improve hair transplant and regeneration techniques.
research Advances in the Study of Stem-Cell-Enriched Hair Follicle Bulge Cells: A Review Featuring Characterization and Isolation of Human Bulge Cells
Scientists have made progress in understanding hair follicle stem cells, identifying specific genes and markers, and suggesting their use in treating hair and skin conditions.
