Scientists have found a way to create hair follicles from skin cells of newborn mice, which can grow and cycle naturally when injected into adult mouse skin.

Lactate production is important for activating hair growth stem cells.

The hedgehog signaling pathway is crucial for hair growth but not for the initial creation of hair follicles.

Dermatologists need to understand hair products to treat hair and scalp issues better.

Minoxidil boosts growth factor in hair cells, potentially promoting hair growth.

Hair follicle stem cells use specific chromatin changes to control their growth and differentiation.

Some herbal therapies may help with skin conditions, but more research is needed to confirm their safety and effectiveness.

Hair follicle dermal stem cells are key for regenerating parts of the hair follicle and determining hair type.

Hair follicles significantly increase the speed and amount of caffeine absorbed through the skin.

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

Wnt signaling controls whether hair follicle stem cells stay inactive or regenerate hair.

A substance called DKK-1 increases in balding areas and causes hair cells to die when exposed to DHT.

Some medicinal plants can help heal wounds and may lead to new treatments.

Wnt ligands are crucial for hair growth and repair.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Blocking COX, especially COX-2, in the skin can reduce inflammation and pain and may help prevent skin cancer.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Vitamin D and its receptor regulate skin functions like cell growth, immunity, hair cycle, and tumor prevention.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

Understanding hair growth involves complex interactions between molecules and could help treat hair disorders.

Male pattern baldness involves genetics, hormones, and needs better treatments.

Caffeine in cosmetics may reduce cellulite, protect skin, and stimulate hair growth, but more research is needed on its use and effects.

Stem cell self-renewal is complex and needs more research for full understanding.

The document concludes that more research is needed to better understand and treat primary cicatricial alopecias, and suggests a possible reclassification based on molecular pathways.

Patients with certain skin symptoms and high ANA titers should be monitored for potential systemic lupus.

Too much Smad7 changes skin and hair development by breaking down a protein called β-catenin, leading to more oil glands and fewer hair follicles.

Cancer cells often have more copies of TERT and TERC genes, which helps them grow and could affect patient outcomes.

Aging causes skin stem cells to work less effectively.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

Vitamin D is important for skin health and may affect conditions like psoriasis and hair loss, but more research is needed to understand its role fully.
