I used to, but I read this article and apparently letting it air dry can have disadvantages too. I don’t straighten or use a curling iron, but I do use the lowest heat setting of the hair dryer. I have a dyson, fwiw. I have curly hair so I use lots of get which gets rid of frizz, so I don’t need to worry about that.
