research Heterogeneity of neural crest-derived melanocytes
Melanocytes are diverse cells important for pigmentation and skin health, influenced by genetics and environment.
research Extracellular Vesicles in Facial Aesthetics: A Review
Tiny particles called extracellular vesicles show promise for skin improvement and anti-aging in facial care but face challenges like low production and lack of research.
research A review of the etiologies, clinical characteristics, and treatment of canities
Gray hair is caused by reduced melanin production or transfer issues, linked to aging and possibly health conditions, with treatments focusing on color camouflage.
research Optimization of the method for the culture of melanocyte precursors from hair follicles and their activation by 1,25-dihydroxyvitamin D3
1,25-dihydroxyvitamin D3 helps melanocyte precursors from hair follicles grow and produce melanin, aiding vitiligo treatment understanding.
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 Melanocyte Chitosan/Gelatin Composite Fabrication with Human Outer Root Sheath-Derived Cells to Produce Pigment
The technique can isolate cells to help treat skin pigmentation issues.
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 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 Melanocytes and Vitiligo (and Hair Graying)
Melanocytes produce melanin; their defects cause vitiligo and hair graying, with treatments available for vitiligo.
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.
research Morphologic comparison of cultured human epidermis melanocytes,amelanotic melanocytes from hair follicles and mouse melanoma cells observed by atomic force microscope
Melanin granules can be expelled by exocytosis.
research The Hair Pigmentation Unit and Hair Graying
Hair color is determined by melanins produced in hair cells.
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 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 Location and fine structure of melanocytes in human fetal scalp hair follicles.
Melanocytes in the outer root sheath are likely stem cells that grow fast but stay immature.
research Reprogramming of three-dimensional microenvironments for in vitro hair follicle induction
Reprogramming 3D environments can create hair follicles in the lab.
research Melanocyte Pygmentation – Friend or Foe on the Route to Melanoma
Darker skin provides more protection against UV damage and cancer.
research Hair follicle-derived epithelial sheet has potential in vitiligo treatment
Hair follicle-derived sheets can effectively treat vitiligo by repigmenting skin.
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 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 085 Autoantigen screening in C3H/HeJ mouse model of alopecia areata revealed high antigenicity of melanocyte-associated antigen epitopes
Melanocyte-associated antigens may play a key role in alopecia areata and could be targets for new treatments.
research Hair cosmetic alterations
The document concludes that individualized treatments for hair issues are effective, certain hair changes can indicate neurocutaneous diseases, specific lotions improve skin health, laser hair removal works but needs more study on long-term effects, men's cosmetics are diverse, peeling is effective but can have side effects, and facial pigmentation is often due to overactive skin cells.
research When the Circadian Clock Meets the Melanin Pigmentary System
Silencing certain circadian clock genes increases skin pigmentation.
