As far as I know, steroid shots don't cause hair loss, certainly not permanent hair loss. So I'm not sure how to explain or interpret your observation, unless it's the scarring itself that caused the thinning (certainly possible), and you just didn't notice until the injection brought the area to your special attention.
Perhaps asking the doctor who gave you the injection (or one of the transplants) would be a good idea.
Take care.

I'm not sure, but I think the first doctor was correct. If you're uncompfortable taking his word, I'd consult a dermatologist with specail hair expertise. An academic medical center in your area would be a good place to start.

Well, since the doctor who gave me the shot, was a hair transplant surgeon, I'm sure he doesn't believe it would cause permanent hair loss (or at least wouldn't admit to it). He said I have asymmetrical male pale balding.
I only came up my theory after a very prominent hair transplant doctor (and dermatologist) Dr. Bernstein from the New Hair Institute told me that steroid shots can cause skin atrophy and cause permanent hair loss. But I have since talked to other hair transplant surgeons (including one who is a dermatologist) and they agree with your opinion that it can't cause permanent hair loss. But of course, they want to charge me $100 for each series of shots to get rid of the rest of the scar tissue.
If this is temporary, how long would it be before my hair returns?
Or after seven months, should I assume it is asymmetrical male pattern baldness like the first doctor told me?
