You can try minoxidil, it has been approved for hairloss, as I assume you know so this is a silly question. Yes, it can help people grow back hair, even around the temples. Will it help you? Only way to find out is to try it. I wish you luck.
As for Mingebreath's advice I would just like to express a bit of anger and frustration with people going around this site posting false information.
Anyone who has used the search function on this site (or even browsed around for a few minutes as from your question I can tell you have) could tell you that dog saliva, not cat saliva, is an essential catalyst for hair regrowth. Cat saliva will do absolutly nothing for combating your hairloss. Scientists arnt sure why or how this phenomena actually works (they suspect is has to do with hormones released from the animals toungue) but it is, without question, an essential element to ones hairloss regimen. Along with masterbation.
