Hair greying is linked to reduced ATM protein in hair cells, which protects against stress and damage.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Apoptosis may contribute to hair loss in androgenetic alopecia.

Mitochondrial problems in tooth cells lead to bad enamel and dentin development in mice.

Azelaic acid treats acne, rosacea, and hyperpigmentation with minimal side effects.

The new lab-grown skin model is good for testing sunscreen's protection against DNA damage from UV light.

A young Russian girl with Meier-Gorlin syndrome has two new mutations in the CDC6 gene.

Low oxygen levels improve the function of hair and skin cells when they are in direct contact.

Melatonin affects mouse skin and may regulate skin functions.

Sheep wool follicles can metabolize both glucose and acetate using different pathways important for wool growth.

Epigenetic changes control how adult stem cells work and can lead to diseases like cancer if they go wrong.

Melatonin helps regulate hair growth and protects the hair follicle from stress.

Caffeine applied to the scalp can protect hair follicles from UV damage.

Vitamin D receptor may help protect against UV-induced skin cancer.

Mice without the vitamin D receptor are more prone to UV-induced skin tumors.

Some traditional Chinese medicines may have anti-aging benefits and could help with hair growth, but more research is needed.

Nanotechnology is improving drug delivery and targeting, with promising applications in cancer treatment, gene therapy, and cosmetics, but challenges remain in ensuring precise delivery and safety.

Pregnancy right after giving birth in mice lacking IL-10 causes milk that leads to liver issues and hair loss in their babies.

Some human genetic markers work for genetic studies in pig-tailed and stump-tailed macaques, which can help in their conservation.

Zinc is essential for plant growth and human health, but many soils lack enough zinc, affecting crops and potentially leading to health problems.

Anticancer drugs are increasingly found in surface waters, and their long-term environmental effects are not well understood, requiring better testing methods.

Human skin cells produce proenkephalin, which changes with environmental factors and skin diseases.

Oestrogens help maintain healthy skin, heal wounds, and may protect against skin aging and cancer.

Eclipta alba extract may work as an anticancer agent and help reverse drug resistance.

New treatments for hair loss are being developed using molecular biology.

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

Gene therapy shows promise for treating skin disorders and cancer, but faces technical challenges.

Neurohormones help control skin health and could treat skin disorders.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Immunosuppressive and anti-TNF therapies in IBD patients can increase the risk of skin cancer and cause various skin issues.
