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

High mTORC1 activity slows hair growth and causes it to lose color.

Red ginseng oil is believed to have various health benefits and is safe, but more research is needed to fully understand how it works.

Bmpr2 and Acvr2a receptors are crucial for hair retention and color.

Tiny particles called extracellular vesicles show promise for treating skin conditions and promoting hair growth.

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

Nanofat shows promise for facial rejuvenation and treating skin issues but needs more research for long-term safety.

Tiny particles called extracellular vesicles show promise for skin improvement and anti-aging in facial care but face challenges like low production and lack of research.

Some Chrysanthemum samples from the USA, Europe, and China differ in quality and some contain harmful cadmium.

Natural skincare products may help reduce sun damage and support the skin's daily cycle.

Retinoids are effective for various skin conditions and hair loss but have serious side effects, so low doses are recommended.

Cell-based models help test if cosmetic ingredients really work for hair growth and skin health.

Bone marrow stem cells and their medium help hair regrowth.

Researchers created a long-lasting mouse skin cell strain that may help with hair growth research and treatments.

Marine-derived saccharides may help reduce aging effects on skin and hair by promoting cell growth and collagen production.

Araliadiol may promote hair growth like minoxidil without being toxic.

Plant extracts may help prevent or reverse hair graying.

Melanocytes are important for normal body functions and have potential uses in regenerative medicine and disease treatment.

Genetic analysis of rabbits identified key genes for traits like coat color, body size, and fertility.

Hair loss in Androgenetic Alopecia is caused by genetics, aging, and lifestyle, leading to hair follicle shrinkage and related health risks.

People with alopecia have shorter hair follicles and more c-kit, a stem cell factor receptor, which could predict how the condition progresses.

The 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.

Stressed fibroblasts greatly increase melanin production in hair, skin, and eye cells, mainly due to a growth factor called bFGF.

Epimedium extract helps increase skin pigmentation and could be a new treatment for conditions with reduced pigmentation.

New findings suggest potential treatments for melanoma, hyperpigmentation, hair defects, and multiple sclerosis, and show skin microbiome changes don't cause atopic dermatitis.

Some cells may slow melanoma growth, a protein could affect skin pigmentation, a gene-silencing method might treat hair defects, skin bacteria changes likely result from eczema, and a defensin protein could help treat multiple sclerosis.

Hair follicle melanocytes die during hair regression.

SCF and ET-1 together significantly increase skin pigmentation and melanin production.

Patient-derived melanocytes can potentially treat vitiligo by restoring skin pigmentation.

Hair color is determined by different melanins and changes with age.
