I've been experiencing diffuse shedding (scalp) and noticed that most of the hairs that fall out have that little bulb/root at the end - is this good or bad?

I appreciate any input or experience regarding this because I read conflicting information on the internet.

Thanks.

Well, not bad, not good either - that depends on you.
I think, when you see the root at its base, means that this hair will never grow again. It's like a plant. If you cut the leaves...it will grow again but if you pull out the plant with the root...it's impossible for the plant to grow again in the pot. :)

The white bulb is not the hair root – you can’t lose the root. Rather, it is a part of the hair nearest to the root. Since the active hair root doesn’t come out with the hair, there is always the possibility for new growth.
On the other hand, if the fallen hair does not have a white bulb at the end of it, then the hair is broken. This can be caused by blow dryers, perms or chemical processes. Specific treatment shampoos and conditioners can be used to correct this problem.

I have hair loss and find that the white bulb used to be bigger years ago when my hait was healthy (when I had hairs pulled for an employment drug test). When it falls now it is really little. Is there a connection?
