research Treatment of Refractory Vitiligo With a Vellus Hair Punch Graft
A new surgical technique using vellus hair grafts effectively treated vitiligo without causing unwanted hair growth.
research Folliculitis Decalvans Developing 20 Years After Hair Restoration Surgery in Punch Grafts: Case Report
A man developed a rare scalp disorder, Folliculitis Decalvans, 20 years after hair restoration surgery, and it required long-term antibiotic treatment.
research Recipient-Site Influence in Hair Transplantation
The place where hair is transplanted can change its growth rate and length but not its thickness.
research Automated digital image analysis (TrichoScan®) for human hair growth analysis: Ease versus errors
TrichoScan often makes mistakes and needs improvement for correct hair growth analysis.
research Vellus hairs in the frontal scalp in early female pattern hair loss
More vellus hairs in frontal scalp indicate early female pattern hair loss.
research Aging of the hair follicle pigmentation system
Hair grays due to oxidative stress and fewer functioning melanocytes.
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 Complications of Hair Transplant Procedures—Causes and Management
Hair transplants are mostly safe but can have minor complications.
research Advances in Regenerative Stem Cell Therapy in Androgenic Alopecia and Hair Loss: Wnt Pathway, Growth-Factor, and Mesenchymal Stem Cell Signaling Impact Analysis on Cell Growth and Hair Follicle Development
Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.
research Complex Hair Cycle Domain Patterns and Regenerative Hair Waves in Living Rodents
Mice hair growth patterns get more complex with age and can change with events like pregnancy or injury.
research Female Hair Restoration
Hair transplantation is the only permanent solution for female pattern hair loss and can greatly improve quality of life with careful planning.
research Platelet‐rich plasma associated with hair transplants for the treatment of androgenetic alopecia showed no benefits
No benefits found using platelet-rich plasma in hair transplants for male hair loss.
research Novel Treatment Modalities for Hair Loss
New hair loss treatments show promise, but more research is needed to confirm their effectiveness.
research The Basic Science of Hair Biology
Hair disorders are caused by a complex mix of biology, genetics, hormones, and environmental factors, affecting hair growth and leading to conditions like alopecia.
research A prospective, comparative evaluation of axillary hair removal with an 808-nm diode laser at different fluences
Higher fluences in 808-nm diode laser treatments are more effective for axillary hair removal.
research Scarring hair follicle destruction is driven by the collapse of EGFR-protected JAK-STAT1-sensitive stem cell immune privilege
A protein called EGFR protects hair follicle stem cells, and when it's disrupted, hair follicles can be damaged, but blocking certain pathways can restore hair growth.
research Molecular Dissection of Mesenchymal–Epithelial Interactions in the Hair Follicle
Understanding gene expression in hair follicles can reveal insights into hair growth and disorders.
research Inductive Properties of Hair Follicle Cells
Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.
research Molecular Genetic and Endocrine Mechanisms of Hair Growth
Hormones and their receptors, especially androgens, play a key role in hair growth and disorders like baldness.
research Osteopontin Gene is Expressed in the Dermal Papilla of Pelage Follicles in a Hair-Cycle-Dependent Manner
The osteopontin gene is active in a specific part of rat hair follicles during a certain hair growth phase and might affect hair cycle and diseases.
research Biology of Human Hair: Know Your Hair to Control It
Understanding hair biology is key to developing better treatments for hair and scalp issues.
research Genetically Induced Cell Death in Bulge Stem Cells Reveals Their Redundancy for Hair and Epidermal Regeneration
Hair and skin can regenerate without bulge stem cells due to other compensating cells.
research L-Cystine-Containing Hair-Growth Formulation Supports Protection, Viability, and Proliferation of Keratinocytes
The hair-growth formula with L-cystine helps protect and grow hair cells.
research Dysfunction of Hair Growth
Hair growth dysfunction involves various conditions with limited treatment options.
research Hair and scalp dermatoscopy
Dermatoscopy is useful for identifying different hair and scalp conditions and can reduce the need for biopsies.
research Pattern hair loss: Assessment of inflammation and fibrosis on histologic sections
Inflammation and fibrosis are not significantly different in pattern hair loss compared to controls.
research Follicular unit extraction as a treatment modality for stable segmental inguinoscrotal vitiligo: A case report
Follicular unit extraction can effectively treat a specific type of vitiligo.
research Clinically applicable transplantation procedure of dermal papilla cells for hair follicle regeneration
The best method for transplanting skin cells to regenerate hair follicles is the Hemi-vascularized sandwich method, as it produces more mature follicles and promotes hair growth.
research Critical study of hair growth analysis with computer-assisted methods
The Trichoscan system was found to be inaccurate for measuring hair growth, needing better software to be useful.
