The 17 Best Scalp Oils to Soothe Itchiness and Encourage Hair Growth

With scalp health, it's not always clear whether a skincare or haircare approach is best. Oils fall somewhere in between—they can do wonders not only for the skin on your scalp but also for the hair that grows from it.

According to trichologist Kate Holden, there are many potential benefits of applying oils to the scalp. "Tea tree, peppermint, ginger, and cade oil can help alleviate itchy scalps and reduce inflammation," she tells Byrdie. "Coconut oil is sometimes recommended as an emollient to help with dry skin and dandruff, and there is some evidence that rosemary oil may help with hair growth."

We love Kiehl's Magic Elixir, an oil-based formula that can be used on both your scalp and hair. Its hero ingredients include avocado oils and safflower oils, which provide deep moisture and nourishment while minimizing inflammation. You'll also get a dose of rosemary oil, which, as Holden notes, has been shown to support hair growth. Considering you only need a few drops at a time, we appreciate the generously sized bottle. You can use it as a pre-shampoo treatment or an overnight scalp mask, but the brand advises against applying it to wet hair.

Key Ingredients: Tea tree and alma oils, blue algae, kelp | Free of: Gluten, soy, GMOs | Dosage: A few drops per section | Size: 1 oz | Cruelty-Free: Yes

For an option you an quickly pick up at the drugstore, we love the Derma-E Scalp Relief Treatment. This pretty blue tincture calls on tea tree oil to cleanse and reduce buildup, plus blue algae and kelp to promote thicker, healthier hair growth. It feels like menthol upon contact with the skin (so those that don't like tingling may not like this one) and helps address stubborn dry scalp, dandruff, and more.

Best Serum

$36 at Amazon $28 at Ulta

Key Ingredients: Ginger essential oil, birch bark extract | Free of: Sulfates, parabens | Dosage: 1 to 2 drops per section when hair is dry | Size: 1.7 oz | Cruelty-Free: Yes

Holden recommends this serum-style treatment from The Body Shop. The nongreasy formula promises to nourish the scalp and balance oil production while soothing itchy, flaky skin with the help of ingredients such as ginger essential oil and birch bark extract.

Key Ingredients: Rahua and palo santo oils | Free of: Mineral oil, sulfates, dyes | Dosage: Small amount left on overnight | Size: 1.3 oz | Cruelty-Free: Yes

If you're battling dandruff, reach for Rahua Founder's Blend. According to the maker, the rare combination of plant-derived oils dissolves the bacteria that causes the condition, then calms irritation and creates a healthy environment for hair growth. The fragrance is a bit strong, so if you're sensitive to smell, this one might not be for you.

Best for Damaged Hair

Carol's Daughter Goddess Strength 7 Oil Blend Hair & Scalp Oil

$14 $12 at Amazon $12 at Target $13 at Ulta

Key Ingredients: Castor and jojoba oil | Free of: Parabens, mineral oil, dyes | Dosage: Small amount as needed | Size: 4.2 oz | Cruelty-Free: Yes

Key Ingredients: Tea tree and borage seed oils, aloe vera, oat extract | Free of: Sulfates, mineral oil, silicone | Dosage: 1 to 2 drops to affected area | Size: 2 oz | Cruelty-Free: Yes

SheaMoisture Scalp Soother was formulated specifically with wigs, weaves, and braids in mind. Tea tree oil helps dissolve buildup, while borage oil offers immediate relief from tightness, tension, and overall scalp discomfort. The wallet-friendly price doesn't hurt either. The only caveat: Some say the formula is runny, so use a gentle hand when applying.

Best for Curly Hair

$28 at Amazon $28 at Sephora $28 at Target

Apply this treatment oil to your scalp, then run it through your hair and let it sit for 15 minutes before hopping in the shower. After shampooing, you can expect shinier, healthier-looking hair. The citrusy-amber scent is pretty incredible too. Since it's so rich, you may have to use some elbow grease to get it completely out of your hair.

Best Exfoliating

Moroccanoil Dry Scalp Treatment

$40 at Amazon $40 at Sephora $40 at Nordstrom

Key Ingredients: Argan oil, salicylic acid | Free of: Parabens, sulfates, mineral oil | Dosage: 3 to 6 drops per section | Size: 1.5 oz | Cruelty-Free: Yes

$10 at Amazon $10 at Target $25 $10 at Walmart

Key Ingredients: Olive and tea tree oils | Free of: Sulfates, parabens | Dosage: Small amount as needed | Size: 4 oz | Cruelty-Free: Yes

For itch relief, Holden says to look for products containing tea tree oil, like this generously sized blend from As I Am. It's also formulated to dissolve buildup and prevent dandruff while minimizing any flakes you might already have. Just keep in mind that it’s not suitable for frequent use as it is a targeted treatment, so use it sparingly as needed as too much tea tree oil can dry out the hair.

Best Overnight

Key Ingredients: Adaptogenic centella asiatica, lactobacillus ferment, hyaluronic acid | Free of: Sulfates, parabens | Dosage: Small amount as needed | Size: 1.7 oz | Cruelty-Free: Yes

This overnight oil treatment from Aveda helps defend the delicate skin on the scalp from signs of aging (read: shedding, hair loss, and dryness) while you sleep.

Apply it directly to the scalp at bedtime to wet or dry hair and massage it in. Something to keep in mind: It's water-based, so those with natural or chemically treated hair might cause hair to curl up.

The serum is lightweight and nongreasy and even has a nice fresh scent to it. Consistency will be the key with this one, so be patient and apply as directed.

What to Look for in a Scalp Oil

• Type: If you are already experiencing some itchiness or flaking, you'll want to help treat the area with a scalp oil that has soothing ingredients. (If your skin is inflamed or flaking excessively, see a medical professional.) However, if your scalp is already in tip-top condition, opt for a well-rounded formula containing ingredients designed to keep your scalp balanced and hydrated.
• Your Needs: Just like you would with skincare concerns, base your scalp oil choice on what your scalp needs. What works for one scalp may not be a benefit to another. Thanks to today’s massive offering, you’ll find options specially formulated for oily scalp, dry scalp, curly hair, thinning hair—you name it. 
• Ingredients: Do you find yourself to be a fan of a certain ingredient because you love what it does for your skin? Then you’ll most likely love what it could do for your scalp, too. And like skincare, trendy ingredients such as hyaluronic acid, argan oil, biotin, and even niacinamide (vitamin B3) are making their way into many a scalp oil formulation.
