July 2020 in “BMC genomics” The research found genes that change during cashmere goat hair growth and could help determine the best time to harvest cashmere.
January 2025 in “BMC Genomics” Key genes and RNA networks regulate hair growth and follicle density in Rex rabbits.
16 citations,
April 2015 in “Lasers in Surgery and Medicine” Using a fractional laser can stimulate hair growth, but the intensity and duration of inflammation are crucial. Too much can cause ulcers and scarring. Lower beam energy and fewer treatments are recommended to avoid damage.
38 citations,
June 2019 in “International Journal of Molecular Sciences” Tiny particles called extracellular vesicles could help with skin healing and hair growth, but more research is needed.
2 citations,
May 2023 in “Marine Drugs” Marine-derived saccharides may help reduce aging effects on skin and hair by promoting cell growth and collagen production.
December 2024 in “Frontiers in Genetics” EGFR and mTOR inhibitors may help manage Olmsted syndrome symptoms.
25 citations,
June 2022 in “Developmental cell” Overactivating Hedgehog signaling makes hair follicle cells in mice grow hair faster and create more follicles.
1 citations,
July 2017 in “Clinical research in dermatology” Hair loss, known as Androgenetic Alopecia, is often caused by hormones and can be diagnosed using noninvasive techniques. Treatments include topical minoxidil and oral finasteride, with new treatments being explored. There may also be a link between this type of hair loss and heart disease risk.
January 2017 in “Journal of Investigative Dermatology Symposium Proceedings” The 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.
