Go to www.facebook.com/lorealparis and click on “Advanced Haircare” to sign up for a free sample before it hits stores.

You have to “like” the L’Oreal Paris Facebook page and be a U.S. resident age 18 or older.

The site doesn’t say how big the sample is, just that you’ll get it in eight to 12 weeks. The offer is good through Dec. 15 or until the approximately 60,000 supplies are exhausted, the page says.
