hair (and eye) (and nail) changes
Posted: Wed Mar 06, 2019 9:30 am
so i remember noticing changes in the appearance of my irises, and that my hair colour changed when i first made the switch from vegan to omni 13 yrs ago.
today i noticed something else - i have been greying at one temple (more like a white patch) since my late 20s but in recent years there's been more, and the other temple got involved as well.
today though, i found a hair that is white and wiry at the tip for about 75 mm/3'' back. then there's a stark change to flexible 'my colour' hair, all the way (ie 99 mm/3.5'') to the root.
wikipedia informs me that hair growth rates average 12.5 mm/0.5'' per mo. and what was i specifically doing 7 months ago, in addition to all the other groundwork i'd been doing over the past year?
i was working on getting vit d3 back up over 100 nmol/l. in two week-long sessions.
the july 2018 session got me to 90, and coincides with the hair change *if* my growth rate is average.
the second round with d3 got me to 166, but that wasn't until november, so not connected unless my hair grows REALLY really fast.
now to go see if there are studies which show correlation between greying and serum d3 levels haha (later... back to work for now!)
edit: couldn't resist.

d3 implicated, see table 2 (all cases <30 ng/ml aka <75nmol/l; i started last year at 20 ng/ml ie 50 nmol/l)
still loads of deficient/insufficient controls mind you. just not so many.

in this group, d3 not significant - iron and b12 more likely to be correlated
