February 2018 in “BMC Genomics” Certain genetic markers linked to reproductive potential were identified by their impact on a protein's ability to bind to genes.
1 citations,
May 2017 in “InTech eBooks” Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
6 citations,
February 2022 in “The journal of neuroscience/The Journal of neuroscience” Deleting the PTEN gene in mice causes nerve cells to grow larger and heal better after injury, but may cause overgrowth and hair loss in older mice.

42 citations,
March 2008 in “Molecular and Cellular Endocrinology” Hormones and neuroendocrine factors control hair growth and color, and more research could lead to new hair treatment options.
36 citations,
November 2009 in “Journal of Investigative Dermatology” Prolactin may affect hair growth differently based on gender and scalp area.
25 citations,
December 1992 in “Seminars in cell biology” Skin stem cells are maintained by signals from nearby cells and vary in their ability to renew and mature.
62 citations,
July 1993 in “Journal of Investigative Dermatology” Hair growth is influenced by interactions between skin layers, growth factors, and hormones, but the exact mechanisms are not fully understood.
March 2024 in “Journal of Endocrinological Investigation” Finasteride treatment in rats changed the expression of genes related to psychiatric and neurological functions, and these changes persisted after stopping the drug.
