Hi. You may have read this before, but I did a little 'digging' on the internet to see if I could find anything that might help out and found this article:
About 50% of patients' hair will regrow in one year without any treatment.[1] If the affected region is small, it is reasonable to observe the progression of the illness as the problem often spontaneously regresses and the hair grows back. In 90% of cases, the hair will, ultimately, grow back. In the other 10%, only some or no hair will regrow.
In cases where there is severe hair loss, there has been limited success treating alopecia areata with clobetasol or fluocinonide, steroid injections, or cream. Steroid injections are commonly used in sites where there are small areas of hair loss on the head or especially where eyebrow hair has been lost. Some other medications used are minoxidil, irritants (anthralin or topical coal tar), and topical immunotherapy cyclosporine, each of which are sometimes used in different combinations.
Oral corticosteroids decrease the hair loss, but only for the period during which they are taken, and these drugs have adverse side effects.[3]
Initial stages may be kept from increasing by applying topical corticosteroids. However, topical corticosteroids frequently fail to enter the skin deeply enough to affect the hair bulbs, which are the treatment target.[3]

Hope that helps atleast a little! :-)
