I always give my hair a Henna treatment when fall starts. I always choose the red-ish color. My hair is several colors from dark brown to blond ends, so the result is a bit like autumn-colors on my head and it feels fitting to do it once a year around the time the fall starts.
I have some Lindebloesemwater that I have red works as a hairwash very well. I have not tried it yet but I will very soon.
