I had a look at this 'fairy' site you mention Dawn.

It is quite fascinating to notice someone else has picked up on the 'fairies' on the hair. I have been noticing this for some time also. I have taken many photographs and discovered "little people" sitting on the top of people's heads and also sitting in their ears and eyes as well. I will have to post photos on my forum about it, to demonstrate what I am seeing.

The implications as to of what exactly the fairies are doing on/in - our heads/ear/eyes, is quite exciting!
