Shu Uemura Essence Absolue Nourishing Taming Overnight Serum
The top-rated Shu Uemura Essence Absolue Nourishing Taming Overnight Serum ($69) is a rich oil that provides a ton of moisture to dry hair. Its magical ingredient is red camelia oil, which nurtures hair overnight so it's smooth and protected once the sun rises. I don't rinse this product out and find it leaves my hair shiny (not greasy) and well-hydrated even after a long period in the sun.
