120-150 / 1000+ results research Internal structural changes in age‐related curved hair due to cyclical extension: An IR spectroscopy study
Age-related hair curvature increases due to internal structural changes from grooming.
research Two different techniques for frontalis suspension using Gore-Tex to treat severe congenital ptosis
Gore-Tex is effective for severe congenital ptosis, with the open approach better for no lid crease and the closed approach better for a preserved crease.
research 250 Sweat glands shrink upward with aging, causing dermal layer defects that lead to loss of skin elasticity and wrinkling-establishment of 3D imaging method for skin appendages
Aging causes sweat glands to shrink and move upward, leading to less elastic skin and more wrinkles.
research Paired Ear Creases of the Helix (PECH): A Possible Physical Sign
Ear creases might indicate heart disease risk, needing more research.
research Association of fibrosis in the bulge portion with hair follicle miniaturization in androgenetic alopecia
Fibrosis in the bulge area of hair follicles can cause hair thinning in male pattern baldness, and drugs that inhibit fibrosis might help reverse this.
research Adipose Infiltration of the Dermis, Involving the Arrector Pili Muscle, and Dermal Displacement of Eccrine Sweat Coils: New Histologic Observations in Frontal Fibrosing Alopecia
The conclusion is that fat tissue in the skin is a new finding in Frontal fibrosing alopecia and may contribute to hair follicle and muscle degeneration.

research Nucleation and growth of macrofibrils in trichocyte (hard-α) keratins
Sheet formation is key to macrofibril structure differences in wool.
research Characterization of Hair Follicle Bulge in Human Fetal Skin: The Human Fetal Bulge Is a Pool of Undifferentiated Keratinocytes
research Morphological analyses in fragility of pili torti with Björnstad syndrome
Pili torti hair is fragile due to loose keratin filaments and weak disulfide bonds.
research Mechanical forces across compartments coordinate cell shape and fate transitions to generate tissue architecture
Mechanical forces are crucial for shaping cells and forming tissues during development.
research Characteristic microstructure of curved human hair
Curved human hair has different structures on its convex and concave sides.
research Analysis of slenderizing human hair fibers surface morphology
research Flexural follicular lichen planus
Flexural follicular lichen planus is a rare skin condition affecting body folds.
research 861 Frontal fibrosing alopecia (FFA) under dynamic optical coherence tomography (D-OCT)
D-OCT shows increased blood vessel growth in response to tissue damage in Frontal Fibrosing Alopecia and is useful for diagnosis and monitoring.
research Management of forehead wrinkles
research The Role of Interface Geometry and Appendages on the Mesoscale Mechanics of the Skin
Skin's uneven surface and hair follicles affect its stress and strain but don't change its overall strength, and help prevent the skin from peeling apart.
research 439 Gradients of Mesenchymal Stiffness Control Sweat Gland Cell Fate Specification During Morphogenesis
Mesenchymal stiffness affects sweat gland cell development.
research Novel Tissue Mechanics-Guided Cellular Flows Enable the Evolution of Feather Follicles
Cellular flows and tissue mechanics guide feather follicle formation in birds.
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 The developmental basis of fingerprint pattern formation and variation
Fingerprints form uniquely before birth due to specific genetic pathways and local signals.
research Growth Factor and Growth Factor Receptor Localization in the Hair Follicle Bulge and Associated Tissue in Human Fetus
research Epithelial skirt and bulge of human facial vellus hair follicles and and associated Merkel cell-nerve complex
Merkel cells are abundant in facial vellus hair follicles, especially during the anagen phase.
research Subepithelial superficial lymph vessels in the airway: a histological study using human fetuses and elderly cadavers
Lymph vessels in airways vary by location, with the most in the upper pharynx and changes after birth.
research Cyclical dermal micro-niche switching governs the morphological infradian rhythm of mouse zigzag hair
Mouse zigzag hair bends form due to a 3-day cycle of changes in hair progenitors and their environment.
research Fibroblast growth factor 5-short (FGF5s) inhibits the activity of FGF5 in primary and secondary hair follicle dermal papilla cells of cashmere goats
FGF5s can block the effects of FGF5, which may help control hair growth in cashmere goats.
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.
