January 2005 in “Experimental dermatology” Melatonin receptors in hair follicles help regulate hair growth and could treat hair loss.
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.
1 citations,
January 2012 in “International journal of trichology” Sheep hair follicle cells can grow a lot but need the dermal papilla to do so.
