Hi Porkypig007,
I have a hooded hair dryer and I only use it for deep conditioning treatments or roller sets. Other than that I never put heat to my hair.
Yes it is better to "air dry" but I think that when you put excessive heat to your hair such as using a blowdryer with high heat on a regular basis is what causes so much damage.
I hope this helps. /images/graemlins/grin.gif
