I am here to tell you that as you age your hair will change colors on its own, without even asking you first. You will go from a cute strawberrish blonde to a shit-water-brown-blonde. It will be great. You will enjoy it.
Over the course of my twenties, I went from generic-mousy-brown to a fantastic, almost-black-brown that nobody in my family has. Now if I could just get it to go back to its teenage texture AND convince all the greys to gather into one badass streak instead of being salt-and-pepper for the next thirty years, I’d be perfectly content with my life.
