January 2015 in “Genetics and molecular research” The RORα gene is active in different parts of cashmere goat hair follicles and may be influenced by melatonin, especially in December when hair growth changes.
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.
