Aveeno can't seem to give away enough samples of their Nourish+ Hair Care Collection. They're now giving away samples from their Facebook page. This is the 4th sample I've signed up for and posted about, from a different source. But hey, I'm not complaining! I can always use shampoo and conditioner samples for traveling.
To sign up for your free sample, visit the Aveeno Facebook page. You must first "like" Aveeno on Facebook, then give the application access to your profile. From there, you can fill out a form for a sample of Nourish+Volumize, Nourish+Shine, Nourish+Revitalize, or Nourish+Moisturize. The sample will be delivered within 4-6 weeks.
