research Molecular Biology of Hair Morphogenesis: Development and Cycling
Understanding hair growth involves complex interactions between molecules and could help treat hair disorders.
research Human Skin Stem Cells and the Aging Process
Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.
research Defining Hirsutism in Chinese Women: A Cross-Sectional Study
An mFG score of 5 or more indicates above-normal hair growth in Southern Chinese women.
research A Role for p75 Neurotrophin Receptor in the Control of Apoptosis-Driven Hair Follicle Regression
The p75 neurotrophin receptor is important for hair follicle regression by controlling cell death.
research Prolactin and Its Receptor Are Expressed in Murine Hair Follicle Epithelium, Show Hair Cycle-Dependent Expression, and Induce Catagen
Prolactin affects hair growth cycles and can cause early hair follicle regression.
research Epidermal Stem Cells and Skin Tissue Engineering in Hair Follicle Regeneration
Hair follicle regeneration needs special conditions and young cells.
research Development and Progression of Alopecia in the Vitamin D Receptor Null Mouse
Mice without the vitamin D receptor gene lose hair due to disrupted hair follicle cycles.
research Prolactin Signaling Influences the Timing Mechanism of the Hair Follicle: Analysis of Hair Growth Cycles in Prolactin Receptor Knockout Mice
Prolactin affects when mice shed and grow hair.
research Prostaglandin D2 Inhibits Wound-Induced Hair Follicle Neogenesis Through the Receptor Gpr44
Prostaglandin D2 blocks new hair growth after skin injury through the Gpr44 receptor.
research Emerging Nonmetabolic Functions of Skin Fat
Skin fat has important roles in hair growth, skin repair, immune defense, and aging, and could be targeted for skin and hair treatments.
research Male Androgenetic Alopecia
DHT, a testosterone byproduct, causes male pattern baldness.
research Nanotechnology-Based Cosmetics for Hair Care
Nanotechnology improves hair care products by enhancing ingredient stability, targeting treatment, and reducing side effects, but more research on its toxicity is needed.
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 5α-Reductase Activity in the Human Hair Follicle Concentrates in the Dermal Papilla
The enzyme that changes testosterone to a stronger form is mostly found in the part of the hair follicle called the dermal papilla.
research GLI2-Specific Transcriptional Activation of the Bone Morphogenetic Protein/Activin Antagonist Follistatin in Human Epidermal Cells
GLI2 increases follistatin production in human skin cells.
research Topical ALA-Photodynamic Therapy for Acne Can Induce Apoptosis of Sebocytes and Down-Regulate Their TLR-2 and TLR-4 Expression
ALA-photodynamic therapy helps reduce acne by causing acne cell death and lowering certain skin protein levels.
research Characterization and Chromosomal Localization of Human Hair-Specific Keratin Genes and Comparative Expression During the Hair Growth Cycle
Two specific hair keratin genes are active during hair growth and decline as hair transitions to rest.
research Smad1 and Smad5 but Not Smad8 Establish Stem Cell Quiescence Critical for Transforming Premature Hair Follicles During Morphogenesis to the Postnatal State
Smad1 and Smad5 are essential for hair follicle development and stem cell sleepiness.
research Immune Modulation of Hair Follicle Regeneration
Immune cells help regulate hair growth, and better understanding this can improve hair loss treatments.
research Wound Healing in Development: Mechanisms and Regulation
Wounds heal without scarring in early development but later result in scars, and studying Wnt signaling could help control scarring.
research Engineering the Niche for Hair Regeneration: A Critical Review
Further research is needed to improve hair regeneration using stem cells and nanomaterials.
research L-Carnitine-L-Tartrate Promotes Human Hair Growth In Vitro
L-Carnitine-L-tartrate may help hair grow and prevent hair loss.
research Hair Keratin KRT81 Is Expressed in Normal and Breast Cancer Cells and Contributes to Their Invasiveness
The hair keratin gene KRT81 is found in both normal and breast cancer cells and helps them invade surrounding tissues.
research Novel Cycle Changes in Scalp Hair Are Caused by Etretinate Therapy
Etretinate therapy can cause hair loss by disrupting the hair growth cycle.
research Alopecia and Platelet-Derived Therapies
Platelet lysate is more effective than activated autologous platelet-rich plasma or saline in improving hair growth after hair restoration surgery.
research To Control Site-Specific Skin Gene Expression, Autocrine Mimics Paracrine Canonical Wnt Signaling and Is Activated Ectopically in Skin Disease
The research suggests that a specific skin gene can be controlled by signals within and between cells and is wrongly activated in certain skin diseases.
research Follicular Density and Ratios in Scarring and Nonscarring Alopecia
Nonscarring alopecia has higher hair density than scarring alopecia, and hair density can help diagnose the type of alopecia.
research Use of Hair Grafting in Scar Camouflage
Hair grafting is a key method for improving scars, especially in areas with hair, by transplanting hair to hide the scar while maintaining its original characteristics.
research Commentary: Unroofing for Hidradenitis Suppurativa, Why and How
Unroofing is an effective, less invasive, and cost-effective surgery for hidradenitis suppurativa with low recurrence and improved patient quality of life.
