The magic of hair oils They’re nourishing yet lightweight, can go on wet or dry hair, and create instant luster. We tested dozens—in the tropics! in the cold! on curls! on thin strands!—to find your perfect match. BY MARISSA OLIVA
Best for hiding split ends : Ojon Rare Blend Oil Moisture Therapy Medium Texture
This lighter version of the brand’s original best-selling oil is made for fine to normal hair that’s dry on the ends. It’s packed with lipids and nutrients that temporarily seal split ends and protect them from further damage.
“My frayed ends looked and even felt smoother.”
—Leslie Robarge, deputy editor
Best for kinky, curly hair: Mizani Supreme Oil
Heavy-duty oils like avocado and apricot make this formula ideal for the driest of hair types. We found that the teensiest bit goes a long way, so spread a little through damp hair, then dab just a touch on ends as needed.
“Just one drop helped my kinky curls air-dry completely frizz-free.”
—Tiffany Blackstone, deputy editor
Best for hot-tool addicts: Dove Pure Care Dry Oil Nourishing Treatment
A slew of our testers were crazy for this super-light, heatprotecting oil. Worked through pre-styling, it made everything from fine, straight hair to thick curls silkier and softer.
“I used it every day before flat-ironing, and my hair was healthier in a week.”
—Molly Klinefelter, copy editor
Best for dyed hair: Garnier Fructis Marvelous Oil Color Illuminate 5-Action Hair Elixir
This is designed to restore shine to color-treated hair—but we took it on a humid Caribbean vacation and discovered it also nixes frizz and keeps salt and chlorine from turning your shade brassy.
“It made my fine blonde hair more luminous—and not at all weighed down.”
—Victoria Kirby, beauty director
Best overnight treatment: Weleda Rosemary Hair Oil
Our testers loved using this in place of a deep-conditioning mask. Before bed, massage a small amount on your scalp, brush it through hair to the ends, then shampoo the next morning.
“My thick hair was suddenly sleeker and more manageable: yay!”
—Samantha Roman, fashion assistant
Best for fine hair: Pantene Advanced + Keratin Repair Keragloss Oil Mist,
It’s geared toward all hair types, but we found that this protein-rich spray, which also helps strengthen hair, was the ideal choice for skinny strands. Just mist a little into your palms, then smooth over the length of damp or dry hair.
“I loved the shine, and the spray made it easy to control how much I used.”
—Cristina Pearlstein, fashion editor
