The only recommendation I have is to make sure the dryer is on low and if it is a loud one, look around for one meant for pets as they are usually a bit quieter. Put the dryer on a stand so you have both hands free.
Then, you can use both hands to comb thru her hair and pet her and sooth her. Give little treats along the way. Build up to how long you have the dryer blowing on her. Just a few seconds at first - break - comb and treat - talking calm and soothing. Then repeat - building how long you keep the dryer on as you go.
Soon, she will associate the dryer with treats
