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 grays due to oxidative stress and fewer functioning melanocytes.

Aging in hair follicle stem cells leads to hair graying, thinning, and loss.

The article concludes that while we understand a lot about how melanocytes age and how this can prevent cancer, there are still unanswered questions about certain pathways and genes involved.

Graying hair happens due to aging and might be delayed by new treatments.

Low ERCC3 gene activity is linked to non-pigmented hair growth.

Wheat sprout extract (fr. 5) promotes hair growth similar to minoxidil.

Polydopamine is a safe, effective, and permanent hair dye that turns gray hair black in one hour.

Melanocyte stem cells in hair follicles are key for hair color and could help treat greying and pigment disorders.

Hair graying is caused by the loss of pigment cells due to poor maintenance of stem cells in the hair follicle.

Different types of inactive melanocyte stem cells exist with unique characteristics and potential to develop into other cells.

Lamivudine might reverse hair graying and needs more research for potential treatments.

Oxidative stress causes hair to gray by damaging and killing pigment cells.

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

Hair ages and thins due to factors like inflammation and stress, and treatments like antioxidants and hormones might improve hair health.

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

Hair graying happens because certain cells aren't maintained properly.

Melatonin affects skin and hair color and protects skin cells, with potential benefits for hair growth and skin health.

Skin aging is a complex process influenced by various factors, leading to wrinkles and sagging, and should be considered a disease due to its health impacts.

The symposium concluded that environmental factors significantly contribute to skin aging.

Mouse skin and hair aging starts at 200 days, with changes in hair follicles and more white hairs as signs of aging.

Mice skin matures by day 200, leading to aging signs like curved hair follicles and white hairs due to changes in skin stem cells.

Gray hair is caused by reduced melanin production or transfer issues, linked to aging and possibly health conditions, with treatments focusing on color camouflage.

Hair graying may be caused by stem cell depletion from stress or melanocyte damage.

The research found that a specific skin cell type not only triggers hair growth but also controls hair color, and that aging can lead to hair loss and color changes.

The paper concludes that understanding melanocyte development can help in insights into skin diseases and melanoma diversity.

The study concludes that regulating apoptosis could lead to new treatments for various skin and hair conditions.

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

Different stem cells are key for hair growth and health, and understanding their regulation could help treat hair loss.

Mouse hair follicles age, causing more white hairs due to fewer pigment stem cells.
