Tiny hairs

I'm still losing hair from my scalp. More than I want to admit. But the quarter sized bald patch that I have on my wrist that I noticed the day after my cortizone injections to my scalp (3 weeks ago) has tiny hairs on it. I have been drinking 2 ounces of aloe vera juice 2 times per day and rubbing aloe vera gel onto my skin. I don't know if it will all grow back or not.
