Do we really need to be concerned about what's in our shampoo? It's on our heads for, like what? 2 minutes tops?

Okay. You’re thinking that it’s just hair. It’s dead. Who cares if there are some toxic ingredients in it? Hair can’t absorb it and we’re washing it out anyway.

It sounds like a logical argument. It's wrong. But it does sound logical.

This is not the area to be lax with your health awareness. Your hair isn’t the concern. It’s the wonderfully thirsty, porous, spongy layers of your scalp! They are the most sensitive and absorbent part of your body.
