I used to have very blonde hair and now I've got really brown hair which is the second most common color.
That's interesting. I myself had blonde hair til like 11 years and then it turned brown.
How dark did it get? Mine is pretty dark but it can vary from dark to light brown.
That's cool. It's pretty light actually when i get sun it turns a little more blondish, but still mostly brown.
That's the same as mine actually. It makes sense that brown hair is so common since it is very common in western populations.
