I bought 2 of the dry oil hair products at Walgreens and plan on going back to get more. It looks like there is also shampoo, conditioner and hair masque to choose from also. This rebate is good through Oct. 1, 2013 too so you have plenty of time to purchase your items. Allow 6-8 weeks for your check to arrive.
