Yes, only if the person uses hair dye.
I just found a hair in my hairbrush that was brown from the root to 4cm down the shaft, then turned white. So it can turn back to its natural colour.
yes it can after some time it will. Your roots will grow out and your natural hair (which is gray) will need to be coloured again.
dye it
yes
yes e.g. if you have black hair it will turn brown , blonde and then grey
temporary haircolor will not effect dark hair, but at the same time gray hair is very resistant to haircoloring in general so it may not take the blonde. If what you want is to turn your gray hair into blonde to look like blonde highlights you would be best going to a hairstylist and tell them you want a weave to cover the gray
Yes
Yes, it is possible for pubic hair to turn gray with age, just like hair on the scalp. This is due to a decrease in melanin production, causing the hair to lose its pigment and appear gray or white.
Get grey hair dye or just let it turn natural grey.
This totally depends. Gray hair can occur very early in life (20's) or very late in life. Some people never turn gray, but instead have white hair. However, in this day and age, you can have whatever color you want!!
yes since I have seen yorkies with blue gray hair Mine had the blue gray hair when we got him at 8mos.
Hair goes grey because pigment cells in the hair base at the roots of the hair stop producing melanin.
