YES!
Some of my hair fell out after diagnosis and i asked my nurses the same question... was it the insulin?
Nope! not the insulin, it's probably stress related. His body would have been under stress pre-diagnosis, and although he may not be emotionally stressed, he will probably be physically stressed... it will stop falling out when his body recovers from what it's been through.
It could also be the time of year... if the weather over there has changed recently, that can actually cause a bit of loss of hair. but it's most likely to be the stress.
