Best oil for itchy scalp and hair loss

Itchy, irritated scalp? Yeah, we know the feeling, and the answer is surprising: oils. They're occlusive, says dermatologist Francesca Fusco, which means they seal in hydration. Here, nine of 'em that lock in moisture and provide soothing relief when your scalp goes berserk.

• 

• Ogx Renewing Argan Oil of MoRoCco Penetrating Oil

  This silicone-spiked formula also contains ultrahydrating argan oil, which "is great for conditioning hair and soothes a dry scalp," says Ron Robinson, a cosmetic chemist and founder of beautystat.com. Plus, it smells rich and sweet (kind of what we'd imagine liquid gold would smell like) and is thick enough to moisturize dry skin; apply a little bit directly onto a damp scalp to seal in the water, and smooth what's left on your hands over the length of damp hair to calm frizz.

• Palmer's Coconut Oil Formula Strong Roots Spray

  This hydrating oil comes in an easy-to-use spray bottle and contains nourishing vitamin E, soothing eucalyptus, peppermint oil, and coconut oil. Its tropical piña colada scent doesn't hurt, either.

• Sheamoisture Organic African Black Soap Dandruff & Dry Scalp Elixir

  "As chemists, we prefer to use a mixture of ingredients because there may be some synergy," says Robinson. This blend of African black soap, tea tree oil (to remove product buildup), plantain enzyme (to soothe), and willow-bark extract (to exfoliate) restores balance to your scalp and soothes it without leaving oily residue behind. Just spray directly onto your scalp and massage gently before styling your hair as you would normally.

• Clear Scalp & Hair Ultra Shea Conditioner

  For a normal scalp that gets dry occasionally, dermatologist Francesca Fusco recommends a conditioner or hair mask with a blend of shea butter and oils, like this one from Clear Scalp & Hair. (Fusco consults for Clear.)

• MoRoCcanoil Dry Scalp Treatment

  This lightweight blend of argan, lavender, and geramium oils is one of Robinson's favorites for soothing very dry scalps. One catch: You'll either love or hate its warm amber scent.

• Ors Hairepair Vital Oils for Hair & Scalp

  "If I were formulating a product, I wouldn't use one oil, I'd use a few," says Robinson. "That's what a consumer should look for." This blend of light oils (including grape-seed, soybean, and sweet almond) easily penetrates the hair and scalp without being too greasy.

• Rejuvenol Dry Scalp and Skin Therapy With Argan Oil

  You've probably learned by now that argan oil is a dry scalp's best friend, and not only does this weightless serum star the super oil, but it also contains hyaluronic acid, which can hold 1,000 times its weight in water, pulling that hydration into your skin. Even better: As a bonus, this pick can also be used to combat dryness elsewhere (like elbows and cuticles).

• One 'N Only Argan Oil Dry Scalp Treatment

  If you're looking for a no-frills product, this one's for you. Though the formula is slightly smelly (think bug repellent, but less pungent), it's easy to use and is effective at providing relief for a dry, itchy scalp.

• Badger Jojoba Herbal Hair Oil for Dry Scalp

  This blend of plant oils (including hydrating jojoba and sunflower oils and antibacterial tea tree oil) moisturizes and soothes the scalp, while peppermint essential oil lends a cool, tingly sensation.
