If you're looking to channel your inner Barbie girl, you can start by using Schwarzkopf Professional's BLONDME All Blondes Rich Shampoo ($23, $16) and All Blondes Rich Conditioner ($25, $18), both of which are used by Robbie's colorist, Jacob Schwartz, to maintain and protect her golden-blonde hair. The best part? They're now 30 percent off, courtesy of Amazon Prime Day.
The brand uses 3D bond creation technology to design its products, which are meant to "stabilize the hair structure and maintain the bonds at home between salon visits." And according to the official website, they cater to the needs of diverse blonde hair types, ranging from normal to coarse.
Both products are sulfate-free, and the key ingredient is cashmere protein complex, which helps to strengthen the inner hair structure and boost moisture.
