Of the many beauty indulgences out there, one of my favorites has to be putting on a hair mask. Unlike, say, getting my roots touched up, which can take hours, or getting my eyebrows threaded, which is quick but painful, a hair mask is painless, effective and fast. Plus, I can multitask with a hair mask in — I usually exfoliate and brush my teeth while I let mine work its magic. That’s why I couldn’t wait to try the new L'Oréal Paris Elvive Dream Lengths Savior Fiber Mask. I was intrigued by the fibrous formula and hoped it would give my dry ends the moisture they crave. Below, find a breakdown of the formula and my full review.The L'Oréal Paris Elvive Dream Lengths Savior Fiber Mask FormulaOne of the reasons I was so excited to try the L'Oréal Paris Elvive Dream Lengths Savior Fiber Mask is because it’s not your traditional, conditioner-like formula. Per the brand, it’s a “fiber concentrate” that you clap between your hands to activate a sticky, stretch-y consistency. It reminded me of the peaks that egg whites form when you beat them to make a meringue — glossy and stiff. The fiber technology is meant to strengthen weakened strands in just two to three minutes, which is how long you’re supposed to leave the mask on for. Added collagen peptides are designed to add strength and preserve the ends of your hair, which tend to bear the brunt of a lot of damage.
