Done all the colors by now. Started with red and black, moved through fire-hues like red orange and pink, tried green, have finally settled these days on a nice pink-purple-blue-teal ombre, which looks nice and mermaidy in my wavy hair. Hardest to keep in is reds and pinks, easiest to keep is blue and green. I love blues and teal because they suit my eyes and skin tone - red and pink make me look flushed, but I do keep pink and purple around my face to keep things bright and fun and show some contrast & movement. Every Sunday I take some me time to refresh any fading colors, try to paint my nails, and take a nice long shower to wash out the dye. Edit to add: if you have medium length hair or longer, pay a professional to do your bleach! I do all my own color, but having someone do the bleach keeps my hair really healthy, even with lots of dye and product. When I did my own bleach, I had to keep cutting my hair shorter and shorter because I would always fry it somewhere and it would get frizzy.
