I never dried my children's hair with a hairdryer when they were little. My grandaughter has never had her hair dried with one either, and hers is very long and thick. Nonsense to say you will catch a cold if you go to bed with wet hair. A cold is caused by a virus, not wet hair! I do remember my dad once bringing home a Morphy Richards hairdryer when I was about 10 (in the mid-60s). It was bright pink - although I think you could also buy a blue one if you were so inclined. My mum looked at it very suspiciously and only used it on "special occasions", and it took so long to dry her hair anyway that she decided it wasn't worth the effort of holding this huge, heavy gadget and it was eventually relegated to the kitchen cupboard along with the "teasmaid" that he also bought on a whim!!!!
