"I'm delving deep into self-care right now, and that includes lots of hair masks to finally get my brittle hair problems under control. This Moroccan Gold Series Black Truffle Mask ($30) is going to do that and more. It's loaded with shea butter and oils to seriously hydrate both hair and scalp, and the truffle gives it a boost of essential fatty acids and antioxidant power. Plus, the incredible scent lingers for days — and fortunately smells more like wild flowers than truffle fries." — Dawn Davis, senior editorial director
