Experts Recommend These Hair Oils for Hydration, Growth, and Overall Hair Health

"Our hair weakens for several reasons—chemically processed treatments, color-treated damage, etc.—and this oil gets to the root of the problem," says celebrity hairstylist Cody Renegar. A key ingredient? Green tea oil, which nourishes the hair and boosts radiance and shine.

"This gel-oil hybrid contains avocado, coconut, shea, and cocoa to add hydration, volume, and shine while protecting against humidity," says Renegar. It also adds a dose of UV protection, which helps protect curls from the havoc caused by the sun's rays.

Justina Blakeney, hairstylist and founder of Niawigs, says this is one of the hardest-working hair oils out there. "Thanks to a combination of maize, pracaxi, camellia, and argan oils, you'll have smooth, luminous hair even after a single use."

This is a lighter version of the bestselling oil; it won't leave fine strands limp and greasy, says Renegar. Still, it effectively controls frizz and adds softness and strength. Use it before styling or as needed for quick conditioning or touch-ups.

Gisou Honey Infused Hair Oil has a mouthwatering aroma that might pass for food, but that isn't the only reason to use it, says Blakeney. "The honey functions as a humectant, drawing moisture to the hair shaft and giving it a glossier, frizz-free appearance."

"Hot tools like blow-dryers and curling irons can leave hair dull, dry, and without luster, but this hair oil—good for all hair types—works to protect hair from the heat and lock in moisture all at the same time," says Teresa Romero, artistic director for Sam Villa and artistic/education director for Jose Luis Salon.

"This hair oil has a combination of strengthening keratin and detoxifying ingredients, including arginine, which helps protect and strengthen chemically lightened hair, preventing it from becoming brassy," says Renegar.

"If you have thicker, curlier hair that's desperate for moisture, try this oil," says Blakeney. It contains an abundance of shea butter to deeply moisturizer and give your hair softness and shine. "The gorgeous finish provides a nourished silky feel, reduces frizz, defines curls, and offers just the right amount of hold," she says.

Use this "miracle-working" product after blow-drying to reduce frizz and add shine to coarse hair, says hairstylist Cindy Marcus. But note: A little goes a long way—a pea-size amount is perfect for most hair types.

Worried about how a heavier oil will sit on your hair? Romero says this lightweight formula is a great option for those with thinner hair, since it provides polish and luster without making locks limp.

"Expensive? Yes, but this ultra-lightweight hair oil has a blend of super-moisturizing oils and plant-derived butter to better condition dry, damaged hair," says Renegar. Ingredients are a mix of natural things like watermelon seed oil and edelweiss flowers, which protect against heat and environmental damage. And to help further justify the price, a little goes a long way.

Renegar says this affordable pick is great because it can be used on any hair type. It's infused with biotin to help nourish and strengthen your hair, while helping to prevent dandruff and heal a dry scalp.

For weightless moisture that expertly tackles frizzy hair and flyaways, try this lightweight serum. "It provides control and protection not only for your natural hair but for any hair extensions you use as well," says celebrity hairstylist Bradley Leake. "I also like that it can be used daily on wet or dry hair."
