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.

Dutasteride and finasteride may reduce sperm count and volume but don't affect movement or shape; effects are reversible after stopping.

Genetic variation in the androgen receptor gene mainly causes early-onset hair loss, with maternal inheritance playing a key role.

The ZIP7 gene helps control zinc levels in cells by moving zinc from the Golgi apparatus to the cytoplasm.

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

The 2003 guidelines suggest that while some treatments can regrow hair in alopecia areata, none alter the disease's progression, and wigs may be the best option for extensive hair loss.

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

Jumonji genes are important for development and their mutations can cause abnormalities, especially in the heart and brain.

Bone Morphogenetic Proteins (BMPs) help control skin health, hair growth, and color, and could potentially be used to treat skin and hair disorders.

Stem cell niches support, regulate, and coordinate stem cell functions.

Blocking JAK-STAT signaling can lead to hair growth.

Some skin medications are safe during pregnancy and breastfeeding, but others can harm the baby and should be avoided.

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

Chemotherapy-induced hair loss significantly affects patients' well-being, and nurses are key in helping them cope, but more research is needed to find effective treatments.

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

Humans lost body hair relatively recently in evolution.

Postpartum depression is linked to changes in brain chemicals, inflammation, stress, and certain genes, and can potentially be identified by markers like specific steroids, serotonin levels, and vitamin D levels.

Some viruses can cause cancer by changing cell processes and avoiding the immune system; vaccines and targeted treatments help reduce these cancers.

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

Facial feminization surgery is effective in helping transgender women appear more feminine and has high patient satisfaction.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

Finasteride may help some male chronic pelvic pain patients, but more research needed.

The conclusion is that FFA and LPP have similar scalp biopsy features, making them hard to distinguish histologically, and FFA may be a specific kind of scarring hair loss.

Foxp3 is crucial for regulatory T cell function, and targeting these cells may help treat immune disorders.

Fat cells in the skin help start healing and form important repair cells after injury.

Diffuse alopecia in women may be related to androgens and iron deficiency, and basic hormone and nutrient screening is useful.

Potassium channel openers are effective in treating heart conditions, high blood pressure, pulmonary diseases, bladder issues, and hair loss, but more selective drugs are needed.

Thyroid hormones help hair grow, reduce hair loss, and increase hair pigment.

Zinc is crucial for nutrition, especially in patients with specific health conditions, and requires careful supplementation and monitoring.

Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.
