I'm not 100% sure what I am looking for, but...

I love the look of oil slick here or of "regular" colored hair that "ombres" into purple, lavender, or frosty blue. While I would love to just dye my hair, I don't think I can for work reasons.

I have never used extensions before. Does anyone have a recommendation for high quality extensions that come in colors? I want them to look as real as possible, and I want to be able to style them with a curling iron or straightener.

TIA!
