Get an Aveeno NOURISH+ Shampoo and Conditioner Sample ”LIKE” Aveeno and scroll down until you see the green “FREE Sample” button, just under the "Scan my profile" banner. Note: Their site has been loading super slow, so you may need to keep trying. I didn't have any issues though. You should get a little pop-up screen saying, "Thank you for requesting a sample! We'll send you a FREE sample from our NOURISH+ Hair Care collection soon."
If you got this previously from this thread, you can double-dip and get another.
