I just reviewed that thread about Sunny D and it is a bit confusing because he was with another foster and it was reported to me that he was improving. When he came to me, my vet was not convinced of the diagnosis...so that is when other testing was done as I mentioned above. That thread really tells nothing about that...but it is a good thread none the less because it shows that often what looks like something may not be. In his case the correct testing had not been done.
Here are some before and after pics of Sunny D....he does have hypothyroidism as well and is on meds for it; but the Melatonin is what made his hair return. It takes about 3 months to work.
