research Peptidylarginine Deiminase Isoforms Are Differentially Expressed in the Anagen Hair Follicles and Other Human Skin Appendages
This study demonstrates that PAD1 and PAD3 are involved in hair follicle differentiation, while PAD1 and PAD2 may play a role in the physiology of sweat glands and arrector pili muscles.
research Comparative aspects of the inner root sheath in adult and developing hairs of mammals in relation to the evolution of hairs
This study suggests that the structure and function of the inner root sheath in mammalian hair may have evolved from simpler forms seen in monotremes, aiding in hair exit without damaging the epidermis.
research Fine structure and immunocytochemistry of monotreme hairs, with emphasis on the inner root sheath and trichohyalin‐based cornification during hair evolution
This study analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.
research Immunocytochemical Localization of Peptidylarginine Deiminase Type III, Trichohyalin and Deiminated Trichohyalin in Infant Rat Dorsal Skin Hair Follicle
This study found that peptidylarginine deiminase type III and trichohyalin are coincidentally expressed in the infant rat hair follicle, but trichohyalin deimination occurs after their expression during development.
research Photobiomodulation for Skin Pigmentation Disorders: A Dual-Function Treatment
This editorial reviews how photobiomodulation therapy might effectively treat both hyperpigmentation and depigmentation skin disorders, but reports no new clinical results.
research Alopecia in a Novel Mouse Model RCO3 Is Caused by mK6irs1 Deficiency
A missing mK6irs1 gene causes hair loss in mice.
research Recognition of the ultrastructure of the hair follicle of Cashmere goats under the transmission electron microscope
This study observed distinct changes in the ultrastructure of Hexi cashmere goat hair follicles throughout the year, highlighting stages with specific cellular and structural characteristics.
research Abnormal inner root sheath of the hair follicle in the loose anagen hair syndrome: An ultrastructural study
This study reports that structural abnormalities in the inner root sheath of hair follicles may cause the hair shaft to be loosely attached in patients with loose anagen hair syndrome.
research Microtubule associated protein (MAP‐2) expression defines the companion layer of the anagen hair follicle and an analogous zone in the nail unit
This study found that MAP-2 is intensely expressed in the companion layer of the hair follicle, suggesting its potential importance to follicle integrity and possible involvement in some types of alopecia.
research A Novel Epithelial Keratin, hK6irs1, is Expressed Differentially in All Layers of the Inner Root Sheath, Including Specialized Huxley Cells (Flügelzellen) of the Human Hair Follicle
This study characterized a new human keratin, hK6irs1, specifically found in the inner root sheath of hair follicles, which suggests its role in the structural integrity and guidance of growing hair shafts.
research Expression and distribution patterns of spermine, spermidine, and putrescine in rat hair follicle
This study observed varying levels of polyamines in different compartments of rat hair follicles, indicating their potential involvement in hair growth, especially in the matrix and inner root sheath layers.
research Histological and dermatoscopic description of sphynx cat skin
This study found that sphynx cats exhibit hair follicle dysplasia with abnormal hair shaft production, but without a reduction in the number of follicles, similar to murine KRT 71 mutants.
research Histochemistry of the porcine pilosebaceous unit
This study found that the distribution of carbohydrates and proteins in porcine hair follicles and sebaceous glands showed minor differences compared to humans.
research Hair removal in hirsute women with normal testosterone levels: a randomized controlled trial of long-pulsed diode laser vs. intense pulsed light
In this study, hirsute women with normal or medically normalized testosterone levels experienced similar, though declining, hair reduction from both intense pulsed light and long-pulsed diode laser treatments over six months.
research A Novel Human Type II Cytokeratin, K6hf, Specifically Expressed in the Companion Layer of the Hair Follicle
This study identified a new type II cytokeratin, named K6hf, exclusively expressed in the companion layer of the human hair follicle, distinguishing it from other keratins and suggesting a unique biochemical role.
research Células-tronco foliculares e aspectos histopatológicos cutâneos tardios após prolongada remoção de pêlos a laser
This study observed that long-term laser hair removal in women may alter hair follicle structures and stem cell interactions, with dermal fibrosis potentially influencing hair regrowth prevention.
research Theoretical considerations in laser hair removal
This article reviews the biological and physical principles of laser hair removal and reports that current laser systems do not consistently achieve permanent hair follicle destruction across treated areas.
research The Nuts and Bolts of Low-level Laser (Light) Therapy
This review discusses the applications of low level laser therapy (LLLT) in wound healing, pain reduction, and treating various conditions, but reports no new clinical results; the authors highlight the need for randomized controlled trials for serious diseases.
research Characterization and quantification of wound-induced hair follicle neogenesis using in vivo confocal scanning laser microscopy
This study found that in vivo confocal scanning laser microscopy accurately quantifies neogenic hair follicles in mice, producing results similar to histology while avoiding fixation artifacts.
research Cytokine loaded layer-by-layer ultrathin matrices to deliver single dermal papilla cells for spot-by-spot hair follicle regeneration
This study found that using layer-by-layer encapsulation techniques on dermal papilla cells can support their function and may help treat hair loss when used in conjunction with freshly isolated epidermal cells.
research Self-Reported Outcome After Diode Laser Hair Removal
In this study, 80% of patients expressed satisfaction with diode-laser hair removal, though multiple treatments were needed for optimal results and were a deterrent for some.
research Laser-assisted Hair Regrowth
This literature review suggests that fractional laser therapies may positively impact hair regrowth in androgenic alopecia, though current evidence is mostly limited to small studies and case reports, highlighting a need for more comprehensive randomized controlled trials to confirm their efficacy and safety.
research Development and Evaluation of Bio fabricated Silver Nanoparticles from Blumea lacera for In-vitro Antibacterial, Antioxidant and Anti-inflammatory Activity
This study found that bio fabricated herbal silver nanoparticles from Blumea lacera extracts demonstrated significant antibacterial activity against Staphylococcus aureus and Escherichia coli, and notable anti-inflammatory effects, though their antioxidant capacity was insignificant compared to the extract.
research Hair Growth Cycle Affects Hair Follicle Destruction by Ruby Laser Pulses
This study found that anagen-phase hair follicles in mice are particularly sensitive to damage by ruby laser pulses, resulting in alopecia without scarring, suggesting enhanced laser hair removal strategies.
research Laser Hair Reduction and Removal
This review discusses the use of laser and intense light sources for hair removal and reports no new clinical results; the authors highlight the potential for aesthetic medicine to include these technologies.
research Efficacy and Safety of Long-Pulsed 755-nm Alexandrite Laser for Keratosis Pilaris: A Split-Body Randomized Clinical Trial
