30 / 292 resultsresearch Melanogenesis During the Anagen-Catagen-Telogen Transformation of the Murine Hair Cycle
Hair stops producing melanin as it transitions from the growth phase to the resting phase.
research Epidermal Pigmentation in the Human Lineage as an Adaptation to Ultraviolet Radiation
Forensic DNA Phenotyping can help predict physical traits from crime scene DNA to identify suspects.
research Influence of Pigmentation on the Codeine Content of Hair Fibers in Guinea Pigs
Darker hair in guinea pigs holds more codeine than lighter hair.
research Oral Zinc Sulphate Causes Murine Hair Hypopigmentation And Is A Potent Inhibitor Of Eumelanogenesis In Vivo
Oral zinc sulphate reduces dark hair color in mice.
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 Chemical And Physical Treatments Damage Caucasian And Afro-Ethnic Hair Fibre: Analytical And Image Assays
Chemical and physical treatments like bleaching, dyeing, and UV radiation damage both Caucasian and Afro-ethnic hair.
research Circulating Testosterone and Feather-Gene Expression of Receptors and Metabolic Enzymes in Relation to Melanin-Based Coloration in the Barn Owl
Barn owls with smaller black spots have higher testosterone levels, which might be due to genetic effects on hormone regulation rather than hormone effects on coloration.
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 Piecing Together the Pigment-Type Switching Puzzle
The document concludes that MGRN1 affects mouse fur color by interfering with a receptor's signaling, but its full role in the body is still unknown.
research Sox2 in the Dermal Papilla Regulates Hair Follicle Pigmentation
Sox2 controls hair color by affecting pigment production in hair follicles.
research How Different Is Human Hair? A Critical Appraisal of Global Hair Fibre Characteristics and Properties Towards Defining a More Relevant Framework for Hair Type Classification
Human hair varies widely and should be classified by curl type rather than race.
research Decreased Benzothiazole-Type Pheomelanin in Regrown Brown Hair in Alopecia Areata
The girl's regrown brown hair had less of certain pigments than her original black hair.
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 Melanogenesis-Promoting Effect of Cirsium Japonicum Flower Extract In Vitro and Ex Vivo
Cirsium japonicum flower extract increases melanin production and could help treat depigmentation conditions.
research Hair Follicle Melanogenesis Reflected in Hair Pigmentation as a Developmental Factor in Alopecia Areata
Hair color is not a risk factor for developing alopecia areata.
research Hair
Hair analysis can detect drug use but is costly and interpretation is complex.
research The Mechanisms of Fur Development and Color Formation in American Mink Revealed Using Comparative Transcriptomics
The research found specific genes and pathways that control fur development and color in young American minks.
research Effect of Laser and Light-Based Systems on Hair Follicle Biology
Lasers can reduce hair growth but may also damage skin.
research Casein Kinase 1 Inhibition in Keratinocytes Enhances the Migration of Melanocyte Precursors in the Hair Follicle via KitL/c-Kit Signaling Pathway
Blocking casein kinase 1 in skin cells can help melanocyte precursors move better, potentially helping with conditions like vitiligo or gray hair.
research Pull Test and Trichogram
Physical exams are important in hair loss diagnosis, considering cosmetic history, systemic diseases, and classifying alopecia types.
research Transgenic Endothelin 3 Regulates Murine Pigment Production and Coat Color
The gene Endothelin 3 makes mice's fur darker by increasing pigment cells and pigment levels.
research Growth Inhibition and Transient Temperature Measurement of Laser-Irradiated Hair Fibers and Follicles
Laser treatment can inhibit hair growth and different hair colors reach different temperatures when lasered.
research The Potential Impact of Melanosomal pH and Metabolism on Melanoma
Melanin may help melanoma cells grow by aiding their metabolism.
