October 2013 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” FGF9 from certain T cells helps create new hair follicles during wound healing, which could potentially be used for hair loss treatments.
June 2013 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” A substance called FGF9 from certain immune cells can trigger new hair growth during wound healing in mice, but humans may not have the same response due to fewer of these cells.
June 2013 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” FGF9 from certain cells can trigger new hair growth during wound healing, but humans have fewer of these cells, which may limit hair regrowth.
April 2018 in “The journal of investigative dermatology/Journal of investigative dermatology” Aging causes changes in scalp cells that can negatively affect hair health.
April 2017 in “Journal of Investigative Dermatology” The hair follicle dermal sheath is essential for hair shedding and needs to communicate with the outer root sheath for normal hair growth cycles.
Testosterone and dihydrotestosterone can slow down the growth of certain hair follicle cells.
