Vitamin d & hair

Vitamin D & hair seemed to spark some interest when research was carried out in the year 2002.
 
The research carried out by Cedars-Sinai Medical Centre/University of California Los Angeles School of Medicine.
 
From what I understand, an active form of vitamin D3 is able to regulate peidermal keratinization. This is done by inducing terminal differentiation. Apparently it is found that mice lacking the vitamin D receptor display defects leading to postnatal alopecia.
 
It seems that from these observations that vitamin D3 is the pathway to regulating hair growth.
According to there tests, 1, 25 dihydroxyvitamin D3 and its synthetic analogs are able to stimulate actual hair growth in nude mice. It seems as though the vitamin d3 analogs impressively stimulated the growth of hair in these nude mice.
 
With out going into too much detail, they found that vitamin D3 analogs were able to act on keratinocytes in order to initiate hair follicle cycling and stimulate hair growth in mice that actually do not grow hair.
 
Keeping this in mind, did you know that your hair follicles actually have large numbers of vitamin D receptors? At this point in time there function is still not known.
 
So, how do we take this bit of interesting info? Should we be getting excited? Men? Baldness? Vatimin d, New hair? ....who knows :-)
