"I was turned on to this haircare brand from hairstylist Mara Roszak recently, and I'm smitten. It's ultra-gentle, smells amazing, and has left my hair feeling silky smooth. I use both the shampoo and conditioner, and yes, it comes in travel sizes," Wu says.

What's so special? This clean formula uses coconut-based surfactants to gently remove buildup from the roots, hydrating and strengthening hair. Its ingredients include the brand's signature Botanicomplex, which is a blend of potent botanicals featuring ginger root, frankincense, grape extract, and walnut to promote scalp restoration and preserve hair color.
