I kinda liked that phase a lot of guys went through where they bleached out their hair, then let their natural color grow out and had the two-tone thing going on
.
I've dyed my hair burgundy and eggplant... I am a bit obsessed with red hair and if it wasn't so much work, I'd have stop-sign red hair all the time. During one phase I had a shorter bob cut, and when the red faded, it was a milder version of LeeLoo from The Fifth Element. Unfortunately, the upkeep was way more work and expense than I was willing to invest. But my favorite thing was to do something unannounced and unexpected, like get a perm on a whim or grow my hair for about three years and then suddenly chop it all off without warning.
It made my friends look twice, and my hairdresser bite her nails.
