Since sometime in the 80's a myth has been circulating that blow drying your hair, and other heat applications, are bad for your hair.  What a load of hot air.

Your body vents tremendous amounts heat through your scalp 24 hours a day.

Short of igniting your hair with a blow torch, heat is not bad for your hair at all.

Frequently people report seeing smoke come from their hair while blow drying.  Rightly so but it is not smoke, it is the hair product evaporating.  What you see is condensation, not smoke.

Any reasonable application of heat is just fine. That is not to say that you can kick start a curling iron full throttle and then just let it sit in your hair for 10 minutes.  Use prudent care.  Otherwise, no problem.
