I've been coloring my hair the same hair color (brand and name of color) for 20 years.
Most people don't either know me with my natural color, or if they did, they don't remember anymore.
I bit my nails down to the nubs for 56 years, but I finally managed to quit and stay quit. I wear gel polish and I love it when people compliment me on how pretty my nails are. Mani/pedis are my only vice.
I've only had my hair done at a salon 3 times in my life, twice in my teens, once in my thirties. Usually I just grow it out until I can't stand it anymore, then cut it and donate.
