Hey Healthyhair,
I'm close to your age and have beein dealing with hairloss for 12 years, so I totally hear you there. Where on your head are you losing hair? Some things are easier to hide for a while than others with products like Topick or Dermatch. A hair transplant is a permanent change, so you need to decide if you are at a stage where you need that, for whatever reason.
I just had my HT with Dr. Hasson after literally 7 years of research. This site has a list of surgeons that are all recommended, some near you, others quite far away. I would suggest you read the reviews section of the forum, take some pictures, and send them to 2-3 drs that you're most interested in. If you could find one in LA, schedule a visit to consult in person.
My advice, and I think everyone here will agree, is to not panic and take your time. The sad reality is that while there are many doctors that perform HTs, there are only a handful of truly great ones. Figure out what your needs are, determine the expense, and make your decision from there. I would just say don't rush or compromise, because if you do there's a chance you'll be unhappy with the result.
Good Luck!
