5.Do Health Problems Turn Hair Gray?
They could. These conditions include:
Lack of vitamin B12
Certain rare, inherited tumor conditions
Thyroid disease
Vitiligo, a condition that destroys pigment-making cells in the scalp
Alopecia areata causes patches of hair (usually ones with color) to fall out. This can look like sudden graying because the hair that’s left is gray or white. When your hair regrows, it could be gray, white, or your normal color.
6.Does Stress Make You Go Gray?
Not directly. But it can cause a condition that causes your hair to shed about 3 times faster than normal. It’s possible that when your hair grows back, it’s gray instead of your original color.
