Dear Dr. Rassman,
I was reading through your blog with regards to histamine positive scalp. (Which I have). My question has to do with autoimmune response and hair transplants. I have a very over-active auto-immune response to some things, especially poison ivy/oak.
Several years ago (2006, age 50 at the time) I had a transplant done. Top-flight hair transplant surgeon! My hair was relatively dense, with receding hairline. The histamine reaction to the transplant was severe, with a tender and red scalp for over 8 months. Today, I have lost over 50% of my 2006 density, my hair has turned nearly white (was salt and pepper), and miniturization is everywhere (when there was none prior to transplant in 2006). A prolonged histamine response can cause antibodies to attack the body (or follicles). I am convinced this is what happened. Any thoughts from the information I have given you?
Well, if you are convinced that is what has happened, what more can I say?
I do not know of histamine response connected with hair loss. Maybe you need an allergist or a good diagnosis of what is going on with your hair. Maybe you have diffuse unpatterned alopecia (DUPA), which is causing more thinning everywhere. I really do not know without examining you.
I realize you are trying to establish a cause and effect relationship between histamine and hair loss, but I do not know how it is relating. When I talk about histamine reaction of the on the scalp it is the redness that a person sees when you scratch the skin/scalp. Your body releases histamine and makes the skin turn red temporarily. This is not an autoimmune response you are referring to. This is not the histamine reaction from poison ivy/oak. Moreover, histamine is used by your body in many other ways (other than auto-immune related). So you see, biochemistry and our human body is very complicated.
