research Regulation of melanocyte stem cells in the pigmentation of skin and its appendages: Biological patterning and therapeutic potentials
Understanding how melanocyte stem cells work could lead to new treatments for hair graying and skin pigmentation disorders.
research Efficacy of an agonist ofα-MSH, the palmitoyl tetrapeptide-20, in hair pigmentation
Palmitoyl tetrapeptide-20 may help reduce hair greying and increase melanin production.
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 Exploring the hair follicle immune privilege state in nonsegmental vitiligo
Hair follicles in nonsegmental vitiligo are better protected from immune attacks than in alopecia areata.
research 1272 p21Waf1/Cip1 is differentially expressed in epidermal versus follicular melanocytes and melanoma cells and is phenotypically regulated by UVB-mediated apoptosis
The protein p21 is more abundant in normal skin cells than in melanoma cells and may help protect against melanoma, with UVB light affecting its levels.
research Human hair follicles display a functional equivalent of the hypothalamic‐pituitary‐adrenal (HPA) axis and synthesize cortisol
Human hair follicles can produce cortisol like the body's stress response system.
research Detection of Functionally Active Melanocortin Receptors and Evidence for an Immunoregulatory Activity of α-Melanocyte-Stimulating Hormone in Human Dermal Papilla Cells
αMSH may help regulate immune responses in hair follicles and its disruption could lead to hair loss.
research The human hair follicle has established a fully functional peripheral equivalent of the hypothamalic‐pituitary‐adrenal‐axis (HPA)
Human hair follicles can produce stress hormones like the body's main stress response system.
research A randomized pilot study to compare hair follicle cell suspensions prepared using trypsin alone versus trypsin in combination with collagenase type I for transplantation in vitiligo
Adding collagenase to trypsin improves cell yield and repigmentation in vitiligo treatment.
research The Psychology of Gray Hair
Stress can cause hair to turn gray by depleting pigment-producing cells through the release of a stress hormone.
research ABSENCE OF H2O2 BREAKDOWN IN HUMAN HAIR MEDULLA IMPLICATIONS IN FOLLICULAR MELANOGENESIS
Human hair medulla doesn't break down hydrogen peroxide, which may affect hair color formation.
research 1229 Melanocyte cell states defined and visualized in developing mouse skin
Researchers found three types of melanocytes in developing mouse skin, each with different genes and locations.
research Disorders of Hair Pigmentation
Hair color is determined by melanin and can be affected by genetic conditions like albinism.
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 Hair follicle stem cells: Walking the maze
Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.
research Regulation of melanocyte stem cell behavior by the niche microenvironment
The environment around melanocyte stem cells is key for hair regeneration and color, with certain injuries affecting hair color and potential treatments for pigmentation disorders.
research Human Hair Graying Revisited: Principles, Misconceptions, and Key Research Frontiers
Hair graying is caused by damage and cell depletion but might be temporarily reversible with drugs and hormones.
research 4th Intercontinental Meeting of Hair Research Societies 2004 The "World of Hair"
The meeting presented new findings on hair stem cells, pigmentation, genetics, and modern hair treatment techniques.
research Isolation of a Novel Population of Multipotent Adult Stem Cells from Human Hair Follicles
Human hair follicles can provide stem cells for regenerative medicine.
research Premature Greying of Hair (Premature Canities): A Concern for Parent and Child
Genetics, stress, and health issues can cause early hair greying, which affects self-esteem, and there's no cure, only hair dye.
research Hair Follicle Pigmentation
Hair color is determined by melanin produced and transferred in hair follicles.
research Topical Application of a Protein Kinase C Inhibitor Reduces Skin and Hair Pigmentation
Applying a specific inhibitor lightens skin and hair color.
research Identification of hair shaft progenitors that create a niche for hair pigmentation
Scientists found cells in hair that are key for growth and color.
research CD34 defines melanocyte stem cell subpopulations with distinct regenerative properties
CD34+ and CD34- melanocyte stem cells have different regenerative abilities.
research Histopathology of aging of the hair follicle
Hair becomes gray and thin as we age, and while most hair loss in older people is due to genetics, there's a chance for gray hair to regain color under certain conditions.
research Dermal Adipose Tissue Secretes HGF to Promote Human Hair Growth and Pigmentation
Fat under the skin releases HGF which helps hair grow and gain color.
research B-Raf and C-Raf Are Required for Melanocyte Stem Cell Self-Maintenance
B-Raf and C-Raf are essential for maintaining melanocyte stem cells to prevent hair graying.
research Vitamin A in Skin and Hair: An Update
Vitamin A is important for healthy skin and hair, influencing hair growth and skin healing, but UV light reduces its levels.
research Characterization of a new, inducible transgenic mouse model with GFP expression in melanocytes and their precursors
A new mouse model helps study melanocyte cells using GFP expression.
