As an ISFP, which stands for introverted, sensing, feeling and perceiving, you're quiet, easygoing, and always down for an adventure — meaning there's no better trend for you than the "underlayer" hair colour. It takes the "classic, peekaboo colour look to a new, more dramatic level with statement shades hidden throughout the nape and ear area of the head," celebrity hairstylist Jason Backe previously told POPSUGAR. That means you can keep to your natural hair colour when it's down, or throw it up in a pony and reveal a whole new side of you.
