The multi-billion dollar hair coloring industry might be in for a bumpy ride ahead.
It’s generally always been assumed that once hair goes gray, it stays that way.
But a new study might be calling that into question.
The study is from researchers at Columbia University, and it’s the first study of its kind to find evidence of natural re-pigmentation, a.k.a. the possibility of actually reversing gray hair.
It could be huge news, but there’s a lot more we have to figure out.
