research Comparative regenerative biology of spiny ( Acomys cahirinus) and laboratory ( Mus musculus) mouse skin
Spiny mice are better at regenerating hair after injury than laboratory mice and could help us understand how to improve human skin repair.
research Fractography of human hair
Moisture content significantly affects how human hair breaks.
research miR-22 promotes stem cell traits via activating Wnt/β-catenin signaling in cutaneous squamous cell carcinoma
miR-22 helps skin cancer grow and spread by activating specific cell signals.
research Characterization and quantification of wound-induced hair follicle neogenesis using in vivo confocal scanning laser microscopy
In vivo confocal scanning laser microscopy is an effective, non-invasive way to study and measure new hair growth after skin injury in mice.
research Light microscopy of the hair: A simple tool to "untangle" hair disorders
Light microscopy is useful for diagnosing different hair disorders.
research Targeted transfollicular delivery of artocarpin extract from Artocarpus incisus by means of microparticles
Microparticles containing artocarpin extract could effectively treat hair loss and acne with minimal side effects.
research Rooster feathering, androgenic alopecia, and hormone-dependent tumor growth: What is in common?
Sex hormones affect hair and feather growth and may help manage alopecia and hormone-dependent cancers.
research Consequences of steroid-5α-reductase deficiency and inhibition in vertebrates
Lack or blocking of SRD5a, a key component in hormone creation, can lead to conditions like pseudohermaphrodism and affect hair growth, bone mass, muscle strength, and reproductive health. More research is needed on its regulation from fertilization to adulthood.
research Normal and Aging Hair Biology and Structure ‘Aging and Hair'
Hair gets thinner, grayer, and changes texture with age due to genetics, environment, and cellular changes, affecting the growth cycle.
research An analysis of canine hair re‐growth after clipping for a surgical procedure
Dog hair grows back in about 14 weeks after being clipped for surgery, and the season doesn't really affect this growth rate.
research Histologic progression of acne inversa/hidradenitis suppurativa: Implications for future investigations and therapeutic intervention
Acne inversa is an epithelial-driven disease where inflammation is caused by cyst rupture, and treatments should focus on preventing tendril growth for better results.
research Expression Profiling Reveals Genes Involved in the Regulation of Wool Follicle Bulb Regression and Regeneration in Sheep
The research identified genes and pathways important for sheep wool growth and shedding.
research Regulation of Hair Shedding by the Type 3 IP3 Receptor
The type 3 IP3 receptor is important for controlling hair loss and growth.
research Expression of the Scube3 epidermal growth factor-related gene during early embryonic development in the mouse
Scube3 gene affects mouse embryo growth in multiple areas, but needs more research.
research The arrector pili muscle, the bridge between the follicular stem cell niche and the interfollicular epidermis
The study suggests that the arrector pili muscle is important for hair health and its damage might contribute to hair loss.
research Rejuvenation of the Male Brow
The document concludes that careful planning and consideration of male brow anatomy are essential for successful facial rejuvenation with cosmetic surgery.
research Photoacoustic Imaging as a Tool for Assessing Hair Follicular Organization
Photoacoustic imaging can accurately assess hair follicle density and orientation for hair transplant planning.
research LncRNA-XIST promotes dermal papilla induced hair follicle regeneration by targeting miR-424 to activate hedgehog signaling
XIST RNA helps regenerate hair follicles by targeting miR-424 and activating hedgehog signaling.
research Gene Expression Profiling of the Intact Dermal Sheath Cup of Human Hair Follicles
Researchers found specific genes in the part of hair follicles that could help treat hair disorders.
research Facial preservation following extreme mummification: Shrunken heads
Shrunken heads retain some facial features and hair characteristics, allowing for limited individual identification.
research Scalp Advancement and the Pretrichial Brow Lift
The surgical technique of scalp advancement and pretrichial brow lift shortens the forehead and lifts brows, is good for women and transgender women with high foreheads, but not recommended for men and has some risks.
research Polymeric micelle mediated follicular delivery of spironolactone: Targeting the mineralocorticoid receptor to prevent glucocorticoid-induced activation and delayed cutaneous wound healing
Using polymeric micelles to deliver spironolactone topically could improve wound healing in skin affected by glucocorticoids.
research Heterogeneity of neural crest-derived melanocytes
Melanocytes are diverse cells important for pigmentation and skin health, influenced by genetics and environment.
research Androgenetic Alopecia
Male pattern baldness may be caused by factors like poor blood circulation, scalp tension, stress, and hormonal imbalances, but the exact causes are still unclear.
research Expression of the RORα gene in Inner Mongolian cashmere goat hair follicles
The RORα gene is active in different parts of cashmere goat hair follicles and may be influenced by melatonin, especially in December when hair growth changes.
research Morphogenetic Mechanisms in the Cyclic Regeneration of Hair Follicles and Deer Antlers from Stem Cells
Hair follicles and deer antlers regenerate similarly through stem cells and are influenced by hormones and growth factors.
research Motoneuron-Specific PTEN Deletion in Mice Induces Neuronal Hypertrophy and Also Regeneration after Facial Nerve Injury
Deleting the PTEN gene in mice causes nerve cells to grow larger and heal better after injury, but may cause overgrowth and hair loss in older mice.
research Aesthetics and Rejuvenation of the Temple
Treating the temple area carefully with combined methods improves facial youthfulness.
research Cutaneous Markers of Disorders Affecting Adult Horses
Skin and hair changes in horses can indicate serious diseases, and recognizing these signs is important for treatment and management.
