research A Rare Repigmentation Pattern in a Vitiligo Patient: A Clue to an Epidermal Stem-Cell Reservoir of Melanocytes?
Repigmentation in vitiligo may come from melanocyte stem cells in the skin.
research Histopathologic Findings of Cutaneous Hyperpigmentation in Addison's Disease and Immunostain of the Melanocytic Population
The study found increased skin pigmentation and variable melanocyte density in a patient with Addison's disease.
research The Early Repigmentation Pattern of Vitiligo Is Related to the Source of Melanocytes and the Choice of Therapy: A Retrospective Cohort Study
Repigmentation patterns in vitiligo depend on melanocyte source, lesion status, and therapy choice.
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 Do Hair Bulb Melanocytes Undergo Apoptosis During Hair Follicle Regression (Catagen)?
Hair follicle melanocytes die during hair regression.
research The Cell Biology of Human Hair Follicle Pigmentation
We need more research on human hair follicle pigmentation, not just mouse models.
research Melanocytes: The New Black
Melanocytes are crucial for skin pigmentation and can affect conditions like melanoma, vitiligo, and albinism, as well as hair color and hearing.
research Pharmacologic Interventions in Aging Hair
Minoxidil and Finasteride are effective for male baldness; more research is needed for hair aging treatments.
research Aging of the Hair Follicle Pigmentation System
Hair grays due to oxidative stress and fewer functioning melanocytes.
research Age-Induced Hair Greying: The Multiple Effects of Oxidative Stress
Hair greying is caused by oxidative stress damaging hair follicles and melanocytes.
research Vitiligo
Vitiligo causes white skin patches and is linked to autoimmune issues.
research MicroRNA/mRNA Regulatory Networks in the Control of Skin Development and Regeneration

Androgens like testosterone affect hair growth and oil production differently across body parts and individuals.
research Premature Graying of Hair: Causes, Associations, and Treatments
Premature graying of hair may suggest health issues and currently lacks effective treatments.
research Premature Graying as a Consequence of Compromised Antioxidant Activity in Hair Bulb Melanocytes and Their Precursors
Gray hair may be caused by lower antioxidant activity in hair cells.
research Melanocytes in Human Embryonic and Fetal Skin: A Review and New Findings
Melanocytes appear in fetal skin early, but their development details are still unclear.
research Protective Effect of Superoxide Dismutase Against Hair Graying in a Mouse Model
Superoxide dismutase (SOD) can prevent hair graying in mice.
research Hair Repigmentation Associated with the Use of Lenalidomide: Graying May Not Be an Irreversible Process
An 81-year-old man's white hair began to regain its original color while he was treated with lenalidomide, suggesting that graying hair might be reversible.
research Hypopigmentation in Frontal Fibrosing Alopecia
FFA patients have fewer melanocytes and thinner skin compared to others.
research Building and Maintaining the Skin
Three types of stem cells help maintain and repair skin, responding to health and environmental changes.
research Mechanisms of Repigmentation Induced by Photobiomodulation Therapy in Vitiligo
Light therapy using helium-neon lasers can help restore skin color in vitiligo by promoting skin cell growth and movement.
research Transcriptomic Regulation of Seasonal Coat Color Change in Hares
Genes related to pigmentation, body rhythms, and behavior change during hares' seasonal coat color transition, with a common genetic mechanism in two hare species.
research Evaluation of the Efficacy of Transdermal Drug Delivery of Calcipotriol Plus Betamethasone Versus Tacrolimus in the Treatment of Vitiligo
Calcipotriol plus betamethasone with microneedling works better than tacrolimus for treating vitiligo.
research Vogt-Koyanagi-Harada Disease Occurring During Pegylated Interferon-α2b and Ribavirin Combination Therapy for Chronic Hepatitis C
Vogt-Koyanagi-Harada disease can develop during interferon therapy for chronic hepatitis C.
research Pigmentation of Regenerated Hairs After Wounding
Regenerated hairs can regain their color if the wound occurs during a certain stage of hair growth, and this process is helped by specific skin cells and proteins.
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 Cell and Tissue Damage After Skin Exposure to Ionizing Radiation: Short- and Long-Term Effects After Single and Fractional Doses
Ionizing radiation causes irreversible skin damage, with single doses leading to acute injury and hair graying, and fractional doses causing more severe long-term tissue damage.
research Loss of Epidermal Melanin Unit Integrity in Human Skin During Melanoma Genesis
Melanoma development can be linked to the breakdown of skin's melanin-producing units.
research Wnt/β-Catenin Signaling Promotes Aging-Associated Hair Graying in Mice
A certain signaling pathway in mice, when increased, causes hair to gray by depleting the cells that give hair its color.
