research Dopamine is a novel, direct inducer of catagen in human scalp hair folliclesin vitro
Dopamine stops hair growth and pigment production in human scalp hair follicles.
research The Hair Pigmentation Unit and Hair Graying
Hair color is due to active pigment cells in hair during growth.
research Human Epidermal Neural Crest Stem Cells (hEPI-NCSC)—Characterization and Directed Differentiation into Osteocytes and Melanocytes
Human epidermal neural crest stem cells can become bone and skin pigment cells, making them useful for therapies.
research Repigmentation through Melanocyte Regeneration in Vitiligo
UV light can help stimulate the growth of new pigment cells from hair follicles in people with vitiligo.
research Wnt10b Promotes Differentiation of Mouse Hair Follicle Melanocytes
Wnt10b helps hair follicle cells mature and produce pigment.
research Dose–hair concentration relationship and pigmentation effects in patients on low-dose clozapine
Clozapine levels in hair reflect dosage and bind more to pigmented hair.
research Hair regrowth in alopecia areata and re‐pigmentation in vitiligo in response to treatment: Commonalities and differences
Hair regrows faster in alopecia areata than skin re-pigments in vitiligo due to differences in stem cells and treatment effects.
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 Paracrine Secreted Frizzled-Related Protein 4 Inhibits Melanocytes Differentiation in Hair Follicle
A protein called sFRP4 from skin cells stops the development of pigment-producing cells in hair.
research Culturing of Melanocytes from the Equine Hair Follicle Outer Root Sheath
Researchers successfully grew horse skin cells that produce pigment from hair follicle samples.
research Stingless bee propolis promotes hair follicle regeneration and melanocyte function in chemotherapy-induced alopecia mouse model
Stingless bee propolis may help regenerate hair follicles and improve pigment function in chemotherapy-induced hair loss.
research Hormonal Induction of Feather Pigmentation in Ptarmigan
Hormones can change ptarmigan feather color from white to pigmented.
research Mechanisms of Hair Graying: Incomplete Melanocyte Stem Cell Maintenance in the Niche
Hair graying is caused by the loss of pigment cells due to poor maintenance of stem cells in the hair follicle.
research The Peripheral Clock Regulates Human Pigmentation
Certain genes control the color of human hair by affecting pigment production.
research Vitiligo: Auto‐immunity and immune responses
Vitiligo is caused by the immune system attacking skin pigment cells.
research Pimecrolimus increases the melanogenesis and migration of melanocytes in vitro
Pimecrolimus boosts melanin production and movement of skin pigment cells.
research Subclinical speckled perifollicular melanosis of the scalp.
The scalp has a natural speckled pattern of increased pigment around hair follicles, possibly linked to local hormone production.
research The Suppression Effects of Fat Mass and Obesity Associated Gene on the Hair Follicle-Derived Neural Crest Stem Cells Differentiating into Melanocyte by N6-Methyladenosine Modifying Microphthalmia-Associated Transcription Factor
The FTO gene hinders stem cells in hair follicles from becoming pigment cells.
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 MiRNA-24 downregulates KLF6 affecting STAT3 protein expression and phosphorylation regulating melanogenesis in cashmere goat coat
miRNA-24 affects goat coat color by controlling proteins involved in pigment production.
research Scalp Micropigmentation
Scalp micropigmentation is a process where tiny dots of pigment are tattooed onto the scalp to create the appearance of a shaved head or fuller hair.
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 Downregulation of nuclear factor-kappaB activation in human keratinocytes by melanogenesis inhibitors
Melanogenesis inhibitors like kojic acid and niacinamide can reduce inflammation and pigment production in skin cells.
research A Microscopic Study of the Hair of the Rabbit, with Special Reference to its Form of Cross-section and Granular Pigmentation
Rabbit hair color is influenced by the shape and distribution of pigment granules.
research Hair Follicle Stem Cells Provide a Functional Niche for Melanocyte Stem Cells
COL17A1 is crucial for preventing hair graying and loss by supporting hair and pigment stem cells.
research Temporary hair removal by low fluence photoepilation: Histological study on biopsies and cultured human hair follicles
Low fluence photoepilation temporarily removes hair by targeting the hair follicle's pigmented area without severe damage.
research Electron paramagnetic resonance (EPR) spectroscopy for investigating murine telogen skin after spontaneous or depilation-induced hair growth
EPR spectroscopy showed that spontaneous hair growth results in thicker skin and less pigmented hair than depilation-induced growth.
research Anatomical development of the skin in foetuses of Red Sokoto goats (Capra hircus)
Red Sokoto goat fetuses develop firmer, pigmented skin with hair follicles as they grow.
