Brooke and Britt shared their favorite and affordable shampoo and conditioner. Tresemme Keratin Smooth Shampoo and Conditioner has great online reviews. 93% of people would recommend the product to a friend. That made them immediately want to try it out. The bottles retail for $5.99, but right now, you can buy 1 and get one for 50% off. Together that is $9 for shampoo and conditioner that can last you up to 6 months! Go to ulta.com for the deal.
