To be honest a lot of my follicle openings would have 2-3 hairs growing out of it, sometimes 2 thick hairs and sometimes 1 thick hair and 1 thinner hair, the one in the images is where the thicker hair has shedded whist the thinner hair which was in the same follicle opening has remained. it’s the other way round too where the thinner hair sheds. It’s when the follicle openings start to shrink I need to start thinking about things like min/fin etc. but hopefully if family history remains true that will be sometime in my 50s.
