Porcupine Tips—If you're over ombre (and who isn't?), but you're still hankering for something high-drama, this look is probably just extreme enough for you. A process like this can work on anyone, since you can choose whatever shade you want. The important thing to remember is that this is still a color treatment and needs to be done correctly — don't try this at home! Once it's done, treat your hair to a restorative conditioner and color-friendly oil on the ends, to maintain a soft, manageable texture.
