Is spontaneous hair colour restoration normal?
So, I am a 44yo male with a speckling of grey hair, and I have been taking a mix of compounds that are often discussed in the forums. I started in about mid-January this year.
Over the last few weeks, I have noticed some grey hairs in my beard that looks strange. The tip is clearly grey, but all the regrowth is black, like the surrounding hair. Judging by the length of regrowth, it roughly coincides with when I started taking my supplement mixture.
As I wasn't on the lookout for such an effect earlier, I have no idea if it was already occurring naturally before I started taking the supplements. I also don't know if colour restoration even occurs spontaneously naturally.
Has anyone else had this experience, either naturally or with supplements?

Went to have a shave, and I decided to snip a few grey-to-black beard hair to record some data.
Here are two, root-end on the left (thicker), tip on the right (very fine). Both have about 6-7mm of grey at the tip, before regrowing in black. I will throw them under the microscope later, to see what the transition zone looks like.

I have been trying out various things over the past couple of years and in fact I have had a very gradual colouring of part of my hair, but more recently it has accelerated.
I think I understand the theoretical underpinning, but I want to study it more. What I have not yet seen (in the most recent iteration) is a white hair turning dark. I have seen lots of dark hairs growing from the start.
