These Scalp Oils Will Help Your Hair Grow Longer and Thicker (2024)

Key ingredients: Ashwagandha, amla, safflower seed oil, sesame seed oil, jojoba seed oil, castor seed oil

Size: 1.8 oz.

Sephora rating: 4.4 oz.

An ELLE editor says: “For so long, wash day was a dreaded chore that I rushed through just so I can say my hair is clean. These days, I like to take my time to give my hair the proper TLC it deserves, and every wash session begins with this Fable & Mane pre-wash oil. Since my hair is also always under a protective style, clarifying shampoos are a must in my routine, so nourishing my hair before cleansing helps keep my strands strong and ready. This oil has all the Ayurvedic goodness to fortify my hair and keep breakage at bay.” —Nerisha Penrose, ELLE.com beauty commerce editor

For thinning hair, this serum is a must-try. The formula features castor oil, along with molecules that make hair look thicker and denser with consistent use.

Key ingredients: Redensyl, Procapil, Baicapil, castor oil

Size: 2 oz.

Sephora rating: 3.8/5 stars

An ELLE editor says: “I honestly can’t recall the number of times I’ve waxed poetic about this hair serum. But whenever anyone comes to me with concerns about thinning, this is the first product that springs to mind. Because it’s so lightweight, I rarely feel like it’s weighing down my hair, even if I don’t wash my hair in between uses. The first time I tried it, I saw baby hairs sprouting all over my scalp after just a few weeks. Plus the volume it gives my hair should be studied. I have a bottle open right now, and there’s probably a backup floating around in my room.” —Carol Lee, ELLE.com associate beauty e-commerce writer

SickScience’s PowerCycle isn’t exactly a hair oil, but it increases hair growth and thickness like one. While it hasn’t been out on the market for long, there’s plenty of proof to back its capabilities; in an eight-week clinical study, 100 percent of participants saw an increase in hair thickness, and they experienced a 15 percent average improvement in hair density or new growth.

Key ingredients: Garlic vesicles, wheat peptide, niacinamide, glycerin, BiotinoylTripeptide-1, rosemary leaf extract

Size: 2.1 oz.

SickScience rating: 5/5 stars

An ELLE editor says: “The before and after pictures featured on the site for this product are unbelievable. How can a product encourage growth like that in just a month? But after trying it for myself, I’m turning into a believer. First of all, it feels thick and moisturizing when you first put it on, but the scalp completely absorbs it so that there’s no greasy residue left behind. I’ve been using it daily for a few weeks now, and I’m already spotting tiny new hairs on my scalp as well as promising new growth on some spots on my hairline, which have been bare for far too long.” —Carol Lee

This scalp oil contains a plethora of nourishing essential oils that encourage circulation, leading to stronger, longer hair, but rosemary oil is the real star. “My mother has long told me about the benefits of rosemary oil. She has a huge bush in front of her home that allows her to make it from scratch for personal and medicinal benefits. Unfortunately, I live in NYC, so I’m nowhere near her precious plant—this rosemary oil plays a close second. I’ve used it off and on for years, and it strengthens your strands with consistent use. It’s also a scalp soother after a protective style that may have tugged at my hair a bit too hard,” says Danielle James, ELLE digital beauty director

Key ingredients: Soybean oil, castor seed oil, rosemary leaf oil, jojoba seed oil, peppermint oil

Size: 2 fl. oz.

Amazon rating: 4.5/5 stars

An ELLE editor says: “I grew up in a family full of strong female voices and personalities—sisters, aunties, and close family friends who were also considered aunties—each of whom helped shape me into the woman I am today. One thing I learned was oiling our scalps was a nightly ritual that none of us dared to skip. This oil, in particular, is a staple in my household. Its soothing formula feels so calming on the scalp, and this has also been key to maintaining healthy hair, especially with protective styles. I can confidently say that this oil is rarely out of stock in my beauty cabinet, and if it is, there’s another one close by.” —Tasha Nicole Smith, ELLE beauty assistant

When dehydrated, hair can be prone to split ends and breakage, making it harder to retain length. With this oil in hand, you don’t have to worry about that. The seven-oil concoction deeply hydrates the scalp and strands, making hair stronger over time.

Key ingredients: Sunflower seed oil, olive oil, jojoba oil, coconut oil, black cumin seed oil, linseed oil, castor oil, soybean oil

Size: 4.2 fl. oz.

Amazon rating: 4.6/5 stars

An ELLE editor says: “Seven oils work together to restore and maintain hair health. I enjoy using this oil because of its nozzle applicator, which gets deep into my braids or twists without making an oily mess. My hair had a phase where it broke off, and using this oil helped me see less fallout. I will always repurchase!” —Nerisha Penrose

Like the other products in Augustinus Bader’s lineup, The Scalp Treatment employs TFC8 technology, a combination of peptides, vitamins, and lipids. The scalp oil also contains oak kernel oil, vitamin B5, and more to balance the scalp’s pH level and bolster the production of collagen and keratin—two essential proteins present in hair.

Key ingredients: Oat kernel oil, watercress, Indian cress, maca root extracts, vitamin B5

Size: 1 oz.

Dermstore rating: 4.8/5 stars

A Dermstore reviewer says: “I occasionally have itchy, dry scalp. I have thin hair, but lots of it. I love the conditioner and this oil. You only need a few drops at the top of your head, massage in and blow dry. It adds shine and body. My hair is looking much healthier. It should last for many months.”

Excess sebum can block the pores on your scalp, which can result in thinner hair. The Act+Acre Cold Processed Scalp Detox contains ingredients like moringa oil and basil leaf to break down buildup. “It promotes scalp health by removing impurities, balancing oil production, and nourishing with antioxidants and vitamins, resulting in improved hair growth, reduced inflammation, and healthier, shinier hair,” says Holdorf. Clarify your scalp, and your hair will thank you.

Key ingredients: Sunflower seed oil, soybean oil, baobab seed oil, moringa seed oil, aloe extract

Size: 3 fl. oz.

Dermstore rating: 5/5 stars

A Dermstore reviewer says: “This is a great product to reset your scalp. It’s soothing, detoxing, and a real treat to use. And the scent is so calming. Perfect for a little pre-shower massage on lazy mornings.”

Oils are often too heavy for low-porosity hair. Instead of sinking in, it can stay on the surface, weighing strands down. However, Tracee Ellis Ross’ Pattern Beauty developed an extremely lightweight oil that hydrates and alleviates flaking without feeling too heavy.

Key ingredients: Safflower oil, jojoba oil, rosehip oil, olive oil, lavender oil

Size: 3.9 fl. oz.

Amazon rating: 4.6/5 stars

An Amazon reviewer says: “I love this product—it’s light and adds moisture to my curls. I was having a hard time finding a product to moisturize and keep my hair curly.”

Even those with oily scalps and hair could use a scalp oil. Argan oil and ginger root, the stars of this Moroccanoil formula, “regulate sebum production, balance the scalp's natural oils, and soothe inflammation,” says Holdorf. In other words, by using an oil, you can help your scalp become less greasy while nourishing your locks at the same time.

Key ingredients: Argan oil, ginger root oil, biotin, peptides, lavender oil

Size: 1.5 oz.

Sephora rating: 4.4/5 stars

A Sephora reviewer says: “I was blown away that this worked! My hair is really oily and normally starts to get oily the day after I wash it, but it’s been three days, and it still feels fresh! I’m really happy with it!”

You should never use this scalp oil on wet hair. Instead, use the precise applicator to apply it on the scalp while your hair is dry, which lets the formula do its magic as it soaks into your strands and skin. The formula quenches dry scalps and even makes your hair feel softer.

Key ingredients: Avocado oil, safflower seed oil, sweet almond oil, rosemary leaf oil

Size: 4.2 fl. oz.

Nordstrom rating: 4.5/5 stars

A Nordstrom reviewer says: “I’ve had very fine hair with a flaky scalp with severe itching for a very long time due to autoimmune issues. I have tried so many different products over the years, and I found that most of them made my symptoms worse—including other oil scalp treatments. This oil is AMAZING. After one use, I had a super clean, itch- and flake-free scalp. My hair has been shinier and looks a lot healthier. As long as you apply it sparingly, it isn’t overly greasy, and it’s really easy to wash out. The only downside for some may be the avocado and rosemary oil smell—which is kind of like salad dressing. I actually enjoy it though.”

This pick from Briogeo moisturizes and stimulates the scalp to improve its health and promote growth. “​​Its pre-wash application allows for maximum penetration and nourishment, making it beneficial for addressing dryness and irritation, and promoting stronger, healthier hair,” explains Holdorf.

Key ingredients: Castor seed oil, grape seed oil, rosemary leaf oil, coconut oil, olive oil, avocado oil

Size: 3.4 oz.

Dermstore rating: 4.8/5 stars

A Dermstore reviewer says: “I’ve seen significantly less breakage during my weekly wash-and-go since I started using this. A great addition to my routine.”

As its name suggests, this scalp oil is like a supplement for your scalp; nutrient-rich botanicals like castor seed oil and pea sprout extract dominate the ingredient list. Holdorf reports that the “unique formula supports hair growth, reduces inflammation, and enhances scalp health, resulting in thicker, healthier hair and a balanced scalp environment.”

Key ingredients: Peptides, hyaluronic acid, castor seed oil, olive oil, pea sprout extract

Size: 2 fl. oz.

Dermstore rating: 4.6/5 stars

A Dermstore reviewer says: “I noticed a soothing sensation that immediately eased the discomfort associated with eczema. The formulation is gentle yet potent, providing a nourishing touch that feels like a sigh of relief for irritated skin. The treatment doesn't just mask the symptoms; it actively promotes healing, making it a standout product in my skin care routine. The lightweight and non-greasy texture of the product makes it easy to apply and ensures that it gets absorbed quickly without leaving any residue. The persistent dryness that used to plague me is now a thing of the past, and the eczema flare-ups have become significantly less frequent.”

This provides a slightly warm sensation that helps stimulate hair follicles and support circulation. “Its revitalizing formula helps alleviate dryness, flakiness, and irritation, while providing a refreshing sensation,” says Holdorf. Your scalp ends up feeling relieved and revitalized, and your hair shinier and healthier.

Key ingredients: Orange peel oil, castor seed oil, soybean oil

Size: 2 fl. oz.

Philip B. rating: 4.9/5 stars

A Philip B. reviewer says: “I am 50 years old and did not know how to handle my hair loss without spending thousands of dollars. Started using the booster and I have seen great results in two months. I use every other day and leave it on for 30 minutes. Highly recommend!”

“The Leonor Greyl Régénérescence Naturelle nourishes and revitalizes the scalp due to its blend of coconut oil, jojoba oil, and essential fatty acids,” says Holdorf. With so much nourishment, your scalp can’t help but stay healthy.

Key ingredients: Borage oil, rosehip oil, apricot kernel oil, lemon peel oil

Size: o.67 oz.

Dermstore rating: 4.7/5 stars

A Dermstore reviewer says: “Would recommend! I already feel like my scalp is healthier after a few uses.”

Nikita Meht is Fable & Mane’s co-founder and creative director.

Lindsay Holdorf is a licensed esthetician and Dermstore’s resident esthetician.

It’s a resounding yes from us! “Hair types and hair conditions differ due to climate, environment, and ethnicity, but the scalp’s needs and the techniques required for a healthy scalp and healthy roots are universal, no matter location, ethnicity, age, or sex,” explains Mehta. However, depending on the climate you live in and your hair type, the amount and type of products you need, as well as how often you need to apply them, can vary. Here’s Holdorf’s easy-to-follow guide:

• Dry Hair: Those with dry hair may benefit from regular scalp oiling to provide moisture and nourishment to both the scalp and hair strands. Lightweight oils like argan oil or almond oil can be suitable for dry hair types.
• Oily Hair: People with oily hair may need to be more cautious with scalp oiling to avoid exacerbating oiliness. Lighter oils such as jojoba oil or grapeseed oil can be more suitable for oily hair types, and it’s essential to avoid applying too much oil or applying it too frequently.
• Normal Hair: Individuals with normal hair can generally benefit from occasional scalp oiling to maintain scalp health and promote hair strength and shine. Medium-weight oils like coconut oil or olive oil can work well for normal hair types.
• Fine or Thin Hair: Those with fine or thin hair may need to use scalp oils sparingly to prevent weighing down the hair and causing limpness. Lighter oils like argan oil or avocado oil can be suitable for fine hair types.
• Thick or Coarse Hair: People with thick or coarse hair may require more substantial oils to effectively moisturize and nourish both the scalp and hair strands. Richer oils like castor oil or shea butter can provide deep hydration for thick or coarse hair types.
