Researchers found new hair and nail genes, how hair reacts to UV, differences in white and pigmented hair growth, nerve changes in alopecia, treatments for baldness and alopecia, a toenail condition linked to a genetic disorder, and that nail fungus is more common in people with psoriasis.

Mouse hair cells respond to male hormones by growing less, and this can be stopped by certain blockers.

Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.

Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.

New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

CD8+ T cells play a key role in graft-versus-host disease in certain mice models.

Exogenous stem cells can effectively integrate into hair follicles, promoting hair growth.

Skin structure complexity and variability are crucial for assessing skin toxicity in safety tests.

Aging changes hair stem cells and their environment, leading to gray hair and hair thinning, but understanding these changes could help develop treatments for hair regeneration.

T-regulatory cells are important for skin health and can affect hair growth and reduce skin inflammation.

Immortalized hair follicle cells could be useful for regenerative medicine and treating inflammation and oxidative stress.

Lavender, lemongrass, rosemary, and chamomile essential oils may help protect cells important for hair growth from damage and could promote hair growth.

Deleting the BRD4 protein in certain skin cells causes hair loss and skin inflammation.

The new skin model can predict how chemicals might cause skin allergies.

Immune cells are crucial for hair growth and preventing hair loss.

Researchers created a mouse cell line to study hair growth and test hair growth drugs.

The document concludes that the hair cycle is a complex process involving growth, regression, and rest phases, regulated by various molecular signals.

Chitosan and surface-deacetylated chitin nanofibers may help treat hair loss.

Adiponectin may stimulate hair growth and could be a potential treatment for promoting hair growth.

Alopecia areata affects hair follicle structure, even in non-balding areas.

A patient with Sézary syndrome showed improvement after treatment and the study suggested follicular mucinosis might indicate future lymphoma risk.

Some brain cancer cells avoid immune system detection, and certain treatments could target this to slow their growth; also, certain fat cell precursors help regenerate hair and skin after injury.

New cell sources for bone tissue engineering are promising due to easier harvesting and availability.

Hair growth is regulated by a combination of hormones, blood vessels, and nerve signals.

Basal cell epithelioma-like changes are most similar to normal basal cells.

Human hair cells can change based on their environment, especially interactions with certain skin cells.

Only skin melanocytes, not other types, can color hair in mice.

Human hair grows better in a special gel that mimics skin.

A new compound, BOI, can help hair grow by changing hair cycle phases and increasing certain cell contents.
