You're entering your "second childhood" maybe.does anyone know of anything that will cause white hair to begin regaining it's old color?
I had that too, usually after stroking my beard while changing the oil in my car, a shower fixed it.
I just got a "burr haircut for the first time in 50 years, noticed I had "patches" like spots on a dfog, so I went back and got shaved ... now It's cooler, but I have discolorations on my scalp like mole colored liver spots .... I"m guessing we all just change with age.
Melatonin is what causes skin coloration I think and hair too ... Dr. Oz had a show on it, where the pot of melatonin by the hair follicle runs dry .... I didn't watch it much, my Sister-in law watches it.
After chemo, sometimes hair grows thicker and darker when it used to be grey .... perhaps you are just regenerating, diet/exercise change.
