Dark hair colour has been common since the dawn of time because the genes for brown and black hair are dominant. The genes for blonde and red hair are recessive and came about from mutations of brown/black hair genes, that's why they are way less common. Just like how 80% or more of the world has brown eyes.
If you're talking about artificial colour though, then yeah. It seems fashionable to dye your hair brown or black nowadays.
