Sulfate-free shampoos have tons of benefits — including preserving color-treated hair and eliminating frizziness — but one of the biggest complaints most people have is that it's hard to get a good lather. Nancy's Kitchen Products solves that problem with their ingenious applicator bottle top that makes it so much easier to apply the product directly onto your roots. This deliciously-smelling product (it smells like frosting!) packs real cleaning power, too. Follow up your shampoo with the brand's argan oil conditioner, which gives your locks a wonderful boost of moisture without weighing it down ($15.99 each, nancyskitchenproducts.com).
