research Regeneration of a New Hair Follicle from the Upper Half of a Human Hair Follicle in a Nude Mouse
The upper half of a human hair follicle can grow a new hair in a mouse, but success is rare.
research Acidic and Basic Hair/Nail (Hard) Keratins: Their Colocalization in Upper Cortical and Cuticle Cells of the Human Hair Follicle and Their Relationship to Soft Keratins
Hair and nail cells share similar proteins, indicating a common differentiation pathway.
research Sympathetic Reinnervation of Intact and Upper Follicle Xenografts into BALB/c-nu/nu Mice
Transplanted rat hair follicles grew hair and had increased but not fully restored nerve connections in mice.
research Aberrant Wnt Signaling Induces Comedo-Like Changes in the Murine Upper Hair Follicle
Overactive Wnt signaling in mouse skin stem cells causes acne-like cysts and shrinking oil glands, which some treatments can partially fix.
research Prevention and Treatment of Linear Scar Formation in the Scalp: Basic Principles of the Mechanism of Scar Formation
New suturing technique with wider intervals and shallow stitches helps prevent scalp scars and promotes hair growth.
research The Arrector Pili Muscle and the Follicular Unit of the Scalp: A Microscopic Anatomy Study
The study found that hair follicles are above muscle connections in the scalp, which may help protect stem cell areas.
research The Arrector Pili Muscle and the Follicular Unit of the Scalp
Each group of hair follicles on the scalp shares one muscle that helps control hair movement.
research Immunopathology of the Human Hair Follicle
The document concludes that immune system abnormalities cause alopecia areata, but the exact process is still not completely understood.
research Embryonic-Like Regenerative Phenomenon: Wound-Induced Hair Follicle Neogenesis
New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.
research Embryology, Histology, and Physiology of the Hair Follicle
The document explains how hair follicles develop, their structure, and how they grow.
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 The Transverse Anatomy of Androgenic Alopecia
The study found that horizontal sections of scalp biopsies are better for analyzing hair loss, showing fewer hairs and more fine hairs in balding areas.
research Fibrosing Alopecia in a Pattern Distribution
Some people with pattern hair loss may also have scalp inflammation and scarring similar to lichen planopilaris.
research A Histologic Review of 27 Patients with Lichen Planopilaris
The conclusion is that certain scalp tissue changes are characteristic of lichen planopilaris, with mucinous perifollicular fibroplasia being a new feature for diagnosis.
research Localized Cutaneous Necrosis Associated with the Antiphospholipid Syndrome
A woman with lupus experienced skin death due to a blood clotting disorder after stopping a blood thinner, which healed with treatment.
research Penetration and Distribution in Human Skin Focusing on the Hair Follicle
Targeting drugs to hair follicles can treat skin conditions, but reaching deep follicle areas is hard and needs more research.
research Distinguishing Histopathologic Features of Acantholytic Dermatoses and the Pattern of Acantholytic Hypergranulosis
Different skin diseases show unique patterns of skin cell separation, cell death, and granular layer changes.
research The Spade Sign as a Pathognomonic Histopathologic Feature of Acne Keloidalis: Analysis of 33 Cases of Cicatricial Alopecia
The "spade sign" is a highly specific indicator for diagnosing acne keloidalis.
research Hair Follicle Associated Pluripotent Stem Cells Stimulate Hair Growth in Transplanted Mice
Stem cells from whiskers can be transplanted to stimulate hair growth.
research Inherited Disorders of the Hair
The study concluded that genetic mutations affect human hair diseases and identified key genes and pathways involved in hair growth and cycling.
research Matriptase Expression and Zymogen Activation in Human Pilosebaceous Unit
Matriptase is highly active in hair follicles and sebaceous glands, especially during hair growth phases.
research Alopecia in Epidermolysis Bullosa
The document suggests that certain protein deficiencies and scalp blistering in Epidermolysis Bullosa may cause hair loss.
research Hair Loss in Autoimmune Cutaneous Bullous Disorders
Hair loss in autoimmune blistering skin diseases varies and may regrow with disease control.
research Fibrosing Alopecia in a Pattern Distribution
Fibrosing alopecia in a pattern distribution is a unique hair loss condition that may respond to antiandrogen therapy.
research Permanent Alopecia as a Manifestation of Chronic Graft-Versus-Host Disease of the Scalp: Clinical, Dermoscopic, and Histopathological Observations
Permanent hair loss after a stem cell transplant can be a sign of chronic immune system attack on the scalp.
research Theoretical Considerations in Laser Hair Removal
Laser hair removal effectiveness depends on targeting hair structures without harming the skin, and improvements require more research and expert collaboration.
research Treatment of Frontal Fibrosing Alopecia and Lichen Planopilaris: A Systematic Review
No effective treatment for frontal fibrosing alopecia was found, but oral 5-alpha-reductase inhibitors had the best response; for lichen planopilaris, topical corticosteroids were commonly used but had a high relapse rate.
research Medical Therapy for Frontal Fibrosing Alopecia: A Review and Clinical Approach
Some treatments like intralesional steroids and 5α-reductase inhibitors are effective for frontal fibrosing alopecia, but more research is needed.
research Acquired Scalp Alopecia: A Review
Early diagnosis and treatment are crucial for preventing permanent hair loss in various scalp conditions, and while new treatments are promising, more research is needed to evaluate their effectiveness.
