TL;DR
- The Root of Your Routine: Divi Scalp Serum supports fuller-looking hair and helps reduce scalp buildup, giving you two good reasons to reach for the dropper.
- Itchy Scalp Ally: Pattern Beauty Scalp Serum helps calm a dry, itchy scalp, whether you’re wearing braids, locs, or your curls loose.
With scalp health, it’s not always clear whether a skincare or haircare approach is best; after all, the scalp is skin. That’s where hair oils come in. They fall somewhere in between, working wonders on scalp skin and the hair that grows from it. According to trichologist Kate Holden (who owns a clinic where she treats hair and scalp conditions), applying oils to the scalp has many benefits. “Tea tree, peppermint, ginger, and cade oil can help alleviate itchy scalps and reduce inflammation,” she explains. “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.”
With that in mind, we set out to find the best scalp oils money can buy. We tested countless scalp oils, read reviews, and tapped hair experts for their recommendations. The result: This list of scalp treatments that treat concerns like dry, itchy, or thinning scalps. Without further ado, let’s get into it.

You don’t even need to book a flight to incorporate this into your daily routine (although we wouldn’t blame you if this product inspired a trip to Punta Cana).
Adi Giesey, former beauty editor with type 1C hair: “I love the Ceremonia scalp oil because it doesn’t feel heavy on your hair, has only a subtle scent, and instantly calms my scalp/skin. The texture is super easy to manipulate and massage into the base of your roots, almost a spa-like experience. You truly can’t go wrong with this scalp oil.”

There are so many good things to say about this oil. For one, it contains 13 different nourishing oils that work on both the scalp and the lengths. It’s very lightweight—despite said 13 oils—and it doesn’t weigh down hair when used sparingly. After use, it makes hair feel super soft, adds loads of shine, and moisturizes the scalp in the process.
Shauna Beni-Haynes, former senior editor with 3C/4A hair: “If I have an itch on my scalp, I just massage some of the oil, and it relieves the area immediately. What makes it stand out from other oils I’ve tried is how lightweight it feels. The texture is smooth and liquidy, and it smells yummy thanks to the blend of plant-based oils.”
Best for Damaged Hair
Carol's Daughter Goddess Strength Hair & Scalp Oil
Strengthens breakage-prone hair
Contains a plethora of nourishing oils
Large bottle

This Goddess Strength Hair & Scalp Oil from Carol’s Daughter is a thick and soothing formula that is the perfect addition to your post-shower routine. After shampooing and conditioning, on damp or dry hair, use the pointed tip to apply the oil directly to your scalp and gently massage it in. The ingredients, aka moisturizing castor oil and strengthening black cumin seed, nourish dry scalps and treat heat-damaged strands. Just keep in mind that it can be somewhat heavy, so it’s ideal for thick or curly hair types. (Those with very fine hair may want to opt for something else.)
Jasmine Phillips, former social media editor with type 4B hair: “I first started using the entire Goddess Strength collection from Carol’s Daughter to remedy my hair after suffering from heat damage, and I can definitely say it has made a huge difference in the health, look, and feel of my natural coils. The formula is thick, so I would recommend it for type 4 hair, as it would be too heavy for fine strands.”

Byrdie
Lauren Pardee, associate editorial director with type 1B/2A hair: “I used to have thicker hair and with age (and stress!) I’ve experienced a good amount of thinning and shedding. This serum helps keep your scalp healthy so it thrives—I noticed new baby hairs in three weeks.”
Best for Braids and Protective Styles
Pattern Jojoba Oil Hair Serum
Adds slip for easier braiding
Softens dry ends and boosts shine
Absorbs quickly without a greasy feel
Contains lavender oil, which may irritate sensitive scalps
Type of Product: Hair and scalp oil | Key Ingredients: Jojoba oil, safflower oil, lavender oil | Size: 3.9 oz

The jojoba and safflower oil blend helps hair retain moisture, softens dry ends, and adds shine without a greasy feel. Before braiding, work a few drops through damp or dry hair for extra slip that makes strands easier to handle. Once your style is in place, massage a few drops into exposed areas of your scalp to help keep dryness in check between wash days. It absorbs quickly and didn’t cause scalp buildup during testing, so you can give your scalp some attention without leaving your roots feeling oily. You can also use it as a prewash treatment when it’s time to take your braids down.

Bianca Lambert, tester with thick, type 4 coily hair: “This made braiding my hair so much easier because it gave my hair extra slip sans the greasy feeling.”
What to Look for in Scalp Oils
- Type: Different scalp oils will do different things. If you are experiencing itchiness or flaking, a scalp oil with soothing ingredients like castor oil will be your best bet. (Note: See a medical professional if your skin is inflamed or flaking excessively.) If you want something that’ll eliminate buildup, try something with clarifying properties, like tea tree oil.
- Your Needs: Think of scalp care like skincare, and base your scalp oil choice on 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: Regardless of the type of formula or your needs, seeking, ingredients such as hyaluronic acid, argan oil, biotin (vitamin B7), and even niacinamide (vitamin B3) are ideal for maintaining a healthy, well-balanced scalp.
How We Tested Scalp Oils
We believe in using products we recommend, so we prioritize testing them in real life.

- Factors Considered: Ingredients, product size, design, intended purpose, overall results, and value.
