Too much of anything can be bad for you, and haircare is no exception. You may maintain your mane by washing, conditioning, and treating on a regular basis, but the ingredients in your products may build up and do more harm than good. That’s why Aveeno is introducing the Pure Renewal Collection — a line of natural, gentle products that revive your lavish locks without sulfates and parabens. The formula contains a seaweed extract that cleanses and balances moisture in the hair. It also includes Natrasurf Technology, a potato-derived component that’s sulfate-free and biodegradable, which allows for gentle cleansing without the harsh chemicals. The result: manageable and weightless locks that are up to seven times healthier after regular use.
