Get a free sample of Dove Hair Therapy. Choose Heat Defense or Intense Damage shampoo/conditioner samples. It’s fun to try new hair products through free sampling, and Dove is one of the best companies about sending out samples. You should get your free sample within 8 to 12 weeks.
Update 6/7/09: I got my sample of Heat Defense shampoo/conditioner plus a $1 coupon in my mailbox.
