Repigmentation patterns in vitiligo depend on melanocyte source, lesion status, and therapy choice.

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.

Hair follicle melanocytes die during hair regression.

We need more research on human hair follicle pigmentation, not just mouse models.

Melanocytes are crucial for skin pigmentation and can affect conditions like melanoma, vitiligo, and albinism, as well as hair color and hearing.

Minoxidil and Finasteride are effective for male baldness; more research is needed for hair aging treatments.

Hair grays due to oxidative stress and fewer functioning melanocytes.

Hair greying is caused by oxidative stress damaging hair follicles and melanocytes.

Vitiligo causes white skin patches and is linked to autoimmune issues.

MicroRNAs are crucial for controlling skin development and healing by regulating genes.

Androgens like testosterone affect hair growth and oil production differently across body parts and individuals.

Premature graying of hair may suggest health issues and currently lacks effective treatments.

Gray hair may be caused by lower antioxidant activity in hair cells.

Melanocytes appear in fetal skin early, but their development details are still unclear.

Superoxide dismutase (SOD) can prevent hair graying in mice.

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.

FFA patients have fewer melanocytes and thinner skin compared to others.

Three types of stem cells help maintain and repair skin, responding to health and environmental changes.

Light therapy using helium-neon lasers can help restore skin color in vitiligo by promoting skin cell growth and movement.

Genes related to pigmentation, body rhythms, and behavior change during hares' seasonal coat color transition, with a common genetic mechanism in two hare species.

Calcipotriol plus betamethasone with microneedling works better than tacrolimus for treating vitiligo.

Vogt-Koyanagi-Harada disease can develop during interferon therapy for chronic hepatitis C.

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.

Vitamin A is important for healthy skin and hair, influencing hair growth and skin healing, but UV light reduces its levels.

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.

Melanoma development can be linked to the breakdown of skin's melanin-producing units.

A certain signaling pathway in mice, when increased, causes hair to gray by depleting the cells that give hair its color.

Superoxide dismutase (SOD) can prevent hair graying in mice.

Sox2 controls hair color by affecting pigment production in hair follicles.

An 82-year-old man's white hair regained color after taking etretinate for psoriasis.
