Your hair may feel drier than usual from summer’s rising temperatures or after a year away from the salon. That’s where a moisturizing hair treatment can do wonders. Kathleen Hou, beauty director at the Cut, is a fan of this Christophe Robin serum, which she says transformed her “crispy hair” into locks “so smooth and silky that I kept running my split ends across my face during Zoom calls to make sure that it was real.” Unlike other leave-in conditioners or hair oils she has tried before, just two to three drops of this serum and, she says, “Instead of looking limp or flat, my hair was bouncy and looks like it meets its hydration goals on the daily.” It’s now her go-to after every shower. The serum’s standout ingredient is prickly-pear oil, which is known for being rich in omegas and having double the fatty acid and proteins of argan oil. Right now, the deeply hydrating serum is 30 percent off, bringing it down from $50 to a more affordable $36.
