I really like this intelligent āout loudā thinking. Basically, I think it is very clear that you are correct that hair loss, as with pain and other symptoms result from underlying causes, and there can be very many totally different underlying causes, but have similar symptoms. So we should not expect one silver bullet or mystical energy to cure all ills.
This is clear thinking. Which is why it keeps raising a red flag for me why PEMF should have so many beneficial effects on so many vastly different health issues. And apparently light has the same generalized effect. Iām not suggesting that either one does everything, but both seem to have surprisingly wide ranging benefits. Which brings us back to a consideration of mechanisms, and why hair loss (or any other problem) may benefit from one specific intervention, but someone else with hair loss may not see the same benefit.
Iāll try to boil down my thoughts, please excuse technical gaps and simplicity, I am painting in broad brush strokes:
Many mainstream medical treatments as we all know are targeted to a single mechanism presumed to be the problem. But several things that promote health do not target a single mechanism, and seem generally to be permissive rather than forceful, in the sense that these things allow cells and tissues to function normally, rather than trying to force one specific outcome by coercing one targeted mechanism.
I think three key such things are: nutrition, light, and PEMF
I think all three act on cells to promote many normal and healthy mechanisms of cellular activity. This makes sense to me:
Nutrition: fairly obvious - nutrients are the substrate of all cellular activity.
Light: Fairly obvious - sunlight is essential to life, and increasingly we are learning about the importance of full solar spectrum light in all areas of health
PEMF: Why this should be on the list is not at all obvious. PEMF this is not natural (or is it?). I think PEMF is on this list because PEMF emulates the effects of physical activity and motion. This is why exercise (which should also be on this list) such as simple walking is so essential to health. I hypothesize that PEMF moves ions in and around cells and tissues in the same way that normal physical activity and walking does, and thus it has many similar benefits and acts on many diverse cellular mechanisms.
I have discussed this hypothesis in detail in many other places, but for me this generally explains why a few things (Light, nutrition, PEMF) can have such broad beneficial effects that do not depend on one or two cellular mechanisms.
So, I guess I can see how light, nutrition, and PEMF all could benefit hair loss, without depending on a single mechanism that causes the problem.
