research Human Pollution Exposure Correlates With Accelerated Ultrastructural Degradation of Hair Fibers
Pollution exposure speeds up hair damage.
research Multifunctional Merkel Cells: Their Roles in Electromagnetic Reception, Fingerprint Formation, Reiki, Epigenetic Inheritance, and Hair Form
Merkel cells may have roles in sensing magnetic fields, creating fingerprints, Reiki energy healing, passing on environmental information to offspring, and influencing hair shape.
research Human Skin Color: Origin, Variation, and Significance
Human skin and hair color variation is mainly due to melanin produced by a few genes, with melanin protecting against sun damage.
research HGF/SF Increases Number of Skin Melanocytes but Does Not Alter Quality or Quantity of Follicular Melanogenesis
HGF/SF increases skin melanocytes but doesn't change melanin type or amount.
research A Pair of Transmembrane Receptors Essential for the Retention and Pigmentation of Hair
Bmpr2 and Acvr2a receptors are crucial for hair retention and color.
research Update on Melasma—Part I: Pathogenesis
Melasma's causes include genetics, sun exposure, hormones, and oxidative stress, and understanding these can help create better treatments.
research Impact of Constant Light Exposure During Pregnancy on Skin of Neonatal New Zealand Rabbits: Structural and Ultrastructural Study
Constant light exposure during pregnancy changes newborn rabbits' skin, affecting hair follicles, skin thickness, and pigment cells.
research Melanocytes and Vitiligo and Hair Graying
Melanocytes produce melanin; their defects cause vitiligo and hair graying, with treatments available for vitiligo.

research Cosmetic Considerations in Dark-Skinned Patients
Dermatologists should customize cosmetic treatments for dark-skinned patients to minimize risks and complications.
research Beyond the Epidermal-Melanin-Unit: The Human Scalp Anagen Hair Bulb Is Home to Multiple Melanocyte Subpopulations of Variable Melanogenic Capacity
The human scalp has different types of pigment cells in hair follicles with varying abilities to produce pigment.
research Varicella-Zoster Virus in Actively Spreading Segmental Vitiligo Skin
The study suggests a link between varicella-zoster virus and segmental vitiligo, with evidence of the virus disrupting skin pigment cells.
research Does Nicastrin Deficiency Cause Melanocytotoxicity in Human Skin as in the Fish Counterpart?
Nicastrin deficiency may cause skin cell damage and pigmentation disorders in humans, similar to effects seen in fish.
research The Hair Pigmentation Unit And Hair Graying
Hair color is due to active pigment cells in hair during growth.
research Morphologic Comparison of Cultured Human Epidermis Melanocytes, Amelanotic Melanocytes from Hair Follicles, and Mouse Melanoma Cells Observed by Atomic Force Microscope
