480-510 / 1000+ results research Changes in Characteristics of Murine Hair Follicles and Tissue Stem Cells Throughout Life
Mouse hair follicles age, causing more white hairs due to fewer pigment stem cells.
research Adiponectin negatively regulates pigmentation, Wnt/β-catenin and HGF/c-Met signalling within human scalp hair follicles ex vivo
Adiponectin reduces hair pigmentation and affects hair growth signals.
research A pig model exploring the postnatal hair follicle cycle
Pigs are a good model for studying human hair growth and disorders.
research Pseudopili Annulati in a Dark‐Haired Individual: A Light and Electron Microscopic Study
A dark-haired Chinese girl had hair that looked banded under certain light but was normal under a microscope.
research The effect of flavonoids on regenerated hair follicles with pigmentation
Certain flavonoids can improve the growth of pigmented hair in mice.
research Melanogenesis is coupled to murine anagen: Toward new concepts for the role of melanocytes and the regulation of melanogenesis in hair growth
Hair color production in mice is closely linked to the hair growth phase and may also influence hair growth itself.
research Hair morphogenesisin vitro: formation of hair structures suitable for implantation
Scientists created early-stage hairs from mouse cells that grew into normal, pigmented hair when implanted into other mice.
research Prostanoid receptors in anagen human hair follicles
Human hair follicles contain a complex network of prostanoid receptors that may influence hair growth.
research 15. Hair and Nails
Women with androgenetic alopecia have fewer terminal hairs, phenol in nail surgery is safe, and a new hair transplant method is faster and less damaging.
research Hair cycle and hair pigmentation: dynamic interactions and changes associated with aging
As people age, their hair follicles produce less pigment, leading to gray and white hair, due to factors like reduced enzyme activity and damage to melanocyte DNA.
research Fine Structure of Perifollicular Nerve Endings in Human Hair
research Towards a “free radical theory of graying”: melanocyte apoptosis in the aging human hair follicle is an indicator of oxidative stress induced tissue damage
Oxidative stress causes hair to gray by damaging and killing pigment cells.
research Influence of Depigmenting Chemical Agents on Hair and Skin Color in Yellow (Pheomelanic) and Black (Eumelanic) Mice
Certain chemicals cause hair graying in black mice but not yellow mice.
research Anomalous Fluorescence of White Hair Compared to Other Unpigmented Keratin Fibres
White hair has weaker tryptophan fluorescence than other unpigmented fibers, possibly due to UV exposure or unknown substances.
research Characterization of Growth Secondary Hair in Min Pig Activated by Follicle Stem Cell Stimulated by Wnt and BMP Signaling Pathway
Wnt and BMP pathways stimulate hair growth in Min pigs, with Wnt being more effective.
research Melanocyte Subpopulation Turnover During the Human Hair Cycle: An Immunohistochemical Study
Melanocyte activity in hair follicles is linked to the hair growth cycle, being active in growth phases and inactive in rest phases.
research Removal of Intact Hair Papilla and Connective Tissue Sheath by Plucking Anagen Hairs**From the Department of Dermatology of the University of Hamburg, Germany.
Plucking hairs in a certain way can result in intact hair roots, not related to baldness.
research Human hair keratins
research Interaction of Minoxidil with Pigment in Cells of the Hair Follicle: An Example of Binding without Apparent Biological Effects
Minoxidil binds to hair pigment but doesn't affect hair growth.
research Trichopigmentation or Scalp Dermopigmentation
Trichopigmentation is a non-invasive, reversible treatment for hair loss that offers natural-looking results for both men and women.
research Untersuchungen der Fremdstoffbindung in permanenten Keratinozyten- und Melanozyten-Zelllinien sowie die Eignung von Primärkulturen aus humanen Haarfollikeln zur In-vitro-Messung der Fremdstoffaufnahme im Haar
Unpigmented keratinocytes absorb substances faster, while melanocytes bind more strongly to melanin.
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 Expression and distribution patterns of spermine, spermidine, and putrescine in rat hair follicle
