Hey NoComb
I saw your photos on your earlier post about switching meds. I can't tell for sure, but it looks as if your hair is fairly dense on the sides and I would assume on the back as well. You could get a transplant and it may look good for a year or two. But if you're genetically predisposed (did I say that right?) to lose all of your hair by the time you reach 30, the transplant would be a waste of time and money. Not to mention the fact that you would have permanent scars as a result. I wouldn't want to make that gamble.
However, there are other solutions. I don't necessarily advocate any of them, but you may want to look into them.
(A.) Dr. Feller made a recent post about platelet rich plasma as a hair restoration treatment. (I'm still doing research on that one)
(B.) If you look good with a shaved head, (I don't) you may want to consider that.
(C.) Apparently there have been great advancements in hair pieces and systems. And once again, I'm not advocating. If you read other threads on this forum, you'll see strong arguments for and against. I'm just trying to make sure you're aware of all your options.
