Yes. Way back in college days, I used Clairol to keep my honey blonde from darkening as I got older. Later I had my hairdresser maintain my dark blonde/light brown, while it went gray underneath, and we kept that up for years.
The pandemic was the perfect opportunity to let it grow out, since I wasn’t going to be seeing anybody. That’s how I got through the very awkward stage of having roots dramatically different from the main color. Now my hair is well past shoulder length, and after many trims there’s only maybe an inch left of the faded light brown at the ends. This has made a very interesting gradient as the color phased downward over the past three years.
These days I wear a modest streak of aquamarine over my virgin white hair. Each time my hairdresser refreshes the color streak, I have him offset it a little so there are varying degrees of depth across the width of the streak. Eventually it fades away.
When my blond son was in high school, he wanted to color his hair blue, and I said fine and helped him do it. My rule is: It’s your hair and you can do anything you want with it.
