"Mommy, why is her hair *insert color here*?"

Chances are, you're the first person with green/purple/blue/etc. hair that a child may see in their life. They've never seen a color sprouting out of someone's head that isn't some variation of brown (be it a warm brown, a light brown, a dark brown, etc.).

"You must eat a lot of *insert food that is the same color as your hair*."

This is a dad joke that you'll get a lot, and it will never get any funnier.

"Did you know your hair is *insert color here*?"

No, I had no idea that I had bright green hair. Must've missed it when I looked in the mirror to brush my teeth this morning.

"Wow, that is some *insert color here* hair!"

Thank you...?

"Does that wash out?"

All colored hair dyes are non-permanent. Permanent hair dyes alter the color of your natural hair permanently, for example with hydrogen peroxide, whereas semi-permanent or temporary colors add color on top of your natural one and fade over time.

There is no such thing as a pink hair dye that will last "forever" and not fade away eventually, whether it's after one wash or twenty washes (which is realistically almost impossible to achieve for a pink dye).

So, yes, it will wash out, but most likely not as quickly as a lot of adults would like it to.
