Rac1 is essential for proper hair structure and color.

Advancements in hair biology include new treatments and tools for hair growth and alopecia.

Hair growth and health are influenced by factors like age, environment, and nutrition, and are controlled by various molecular pathways. Red light can promote hair growth, and understanding these processes can help treat hair-related diseases.

Hair in mammals likely evolved from glandular structures, not scales.

IL-6 from stem cells helps repair skin and grow hair.

Alk1 in specific cells is crucial for proper nerve branching and hair function.

The mTurq2-Col4a1 mouse model shows how the basement membrane develops in live mammals.

The document concludes that more research is needed to reduce frequent hospital visits, addiction medicine education improves with specific training, early breast cancer surgery findings are emerging, nipple smears are not very accurate, surgery for older melanoma patients doesn't extend life, a genetic condition in infants can often be treated with one drug, doctors are inconsistent with blood clot medication, a certain gene may protect against cell damage, muscle gene overexpression affects many other genes, and some mitochondrial genes are less active in mice with tumors.

Melatonin affects certain genes and pathways involved in cashmere goat hair growth.

Dandruff might be caused by changes in how hair follicles naturally release oils and an immune response to this imbalance.

Melatonin can increase cashmere yield by altering gene expression and restarting the growth cycle early.

The conclusion is that proper signaling is crucial for hair growth and development, and errors can lead to cancer or hair loss.

Hair loss is common in lupus patients and can be permanent or reversible, depending on the type, with various treatments available.

Follistatin helps hair growth and cycling, while activin prevents it.

iNKT cells can help prevent and treat alopecia areata by promoting hair regrowth.

A man's severe skin reaction from cancer treatment improved with early diagnosis and proper medication.

Two people had unusual ring-shaped hair loss due to an autoimmune disorder.

Androgens can cause hair growth in some areas and hair loss on the scalp.

Stem cell therapy may help treat tough hair loss cases.

CD98hc's role in skin health decreases with age.

Reflective confocal microscopy can potentially diagnose epidermoid cysts without a biopsy.

PRP helps skin regeneration but needs standardized testing for consistent results.

Proper niche formation in Drosophila requires Slit-Robo signaling for cell migration.

The study found that the cause of alopecia areata can be identified through tissue analysis, and vertical sections are enough for diagnosis.

Some alternative medicine treatments might work for skin conditions, but their effectiveness and safety differ a lot.

Nail stem cells and Wnt signaling are important for fingertip regeneration but not sufficient for regenerating more complex limb structures.

High DHA levels delay wound healing and worsen skin repair quality.

Tiny infundibular cysts are the main lesions in chloracne, not comedones.

Grafted rodent and human cells can regenerate hair follicles, but efficiency decreases with age.

The gene Msx2 is crucial for hair follicle regeneration during wound healing.
