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, finger-print 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 Giant pigmented tumour of the scalp—a diffuse neurofibroma or a congenital naevus showing neurofibromatous changes? Immunohistochemical and electron microscopic studies
The tumor likely shows dual neural crest differentiation.
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 The Effect of Ruby Laser Light on Cellular Proliferation of Epidermal Cells
Ruby laser hair removal does not cause increased cell growth in the skin.
research Human hair melanins: what we have learned and have not learned from mouse coat color pigmentation
We know less about human hair pigmentation than mouse coat color, but pH and cysteine levels are key factors.
research SASH1 Mutations and Hereditary Disorders of Pigmentation: Review of Literature
SASH1 gene mutations are linked to various inherited skin pigmentation disorders.
research Plant‐Derived Monomers for Grey Hair Reversal Through Upregulation of Melanogenesis and Tyrosinase Activity
Plant-derived compounds may help reverse grey hair by boosting melanin production.
research Reprogramming of three-dimensional microenvironments for in vitro hair follicle induction
Reprogramming 3D environments can create hair follicles in the lab.
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 Melanocyte Pygmentation – Friend or Foe on the Route to Melanoma
Darker skin provides more protection against UV damage and cancer.
research Trichology to predict efficacy of scalp cooling: New pathologic insights besides encouraging clinical results.
Scalp cooling can effectively prevent hair loss during chemotherapy, improving patients' quality of life.
research The Trotter collection: A review of Mildred Trotter 's hair research and an update for studies of human variation
Hair traits vary widely and are not reliable indicators of ancestry.
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 512 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 Inadequacy 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 Activity evaluation of epidermo-melanin unit and dermal damage in melasma
Melasma results from changes in the skin's pigment and structure, not just pigment cell growth.
research An approach to disorders of pigmentation
The document concludes that pigmentation disorders in animals involve complex interactions between melanocytes and keratinocytes.
research Mechanism of cannabinoid incorporation in hair
Cannabinoids like THC and THCA get into hair through skin oils, not hair color.
research Observation of cultured amelanotic melanocytes from hair follicles by atomic force microscopy
Amelanotic melanocytes from hair follicles are immature and likely don't transfer melanosomes to keratinocytes.
research The Hair Pigmentation Unit and Hair Graying
Hair color is due to active pigment cells in hair during growth.
