Dermatologist Suggested Cortisone for Stress Hair Loss

(male)
I experienced a lot of stress in 08 and now have a patch of hair missing on top left portion. A dermatologist on two occasions injected cortisone and I went to another who said I did not need another injection and gave samples of luxiq. Small stubbles are growing back but does not appear to be terminal hair like on the right side. Any suggestions or just wait and see?

I am not a fan for the use of steroid injections into the scalp to treat any form of hair loss that is not an autoimmune disease. Stress does not qualify as an indication for such treatment, as these injections often causes more permanent hair loss than it helps. Good luck.
