Hair oils aren’t exactly a groundbreaking invention, but here’s the problem: most of the stuff on the shelves may not do much. A lot of the “big name” oils are basically water padded with a splash of oil so they can make claims on the label. That doesn’t mean oils like rosemary, argan, or peppermint don’t work for growth – they might – but nobody really wants to sit at home mixing their own scalp potion.
And with hair health blowing up across social media, the market’s more cluttered than ever. Influencers are pushing every bottle under the sun, prices are all over the place, and half the blends may not deliver. That’s why reviewers for this article stripped it back and worked with dermatologists, aestheticians, and ingredient researchers to nail down the 10 best hair oils that may actually help with growth, thickness, and overall hair health in 2025.

Editors’ Quick Picks
- Best Day-to-Day Oil – St. Felix
- Best for Quick Growth – Toxique
- Best for Men – Mengine
Best Overall Hair Growth Oil
- Form: Oil (100ml)
- Key Ingredients: Cold-pressed argan oil, biotin, broccoli, sunflower
- Price: $36
St. Felix earns the top spot because it may be the most usable oil day in, day out. It’s lightweight enough to leave in without making you look like you dunked your head in a fryer, but still packs clinical-level actives. Broccoli extract works on scalp DHT, biotin may work to strengthen brittle hair, and the formula is formulated to protect from breakage while potentially speeding up growth.
Potential Pros
- Rich in potentially proven DHT blockers like rosemary and saw palmetto
- Biotin for possibly stronger, less brittle hair
- Lightweight and non-greasy
- May be safe on all hair types (even color-treated)
- Absorbs quickly and clinically tested
Cons
Premium pricing compared to simpler blends
Conclusion
St. Felix nails the balance between performance and usability. From follicle stimulation to strengthening, it may be the most well-rounded oil for everyday growth support.
2. Toxique Honey Infused Hair Growth Serum
Best for Women
- Form: Oil serum (220ml)
- Key Ingredients: Moroccan argan oil, rosemary, castor, lavender, peppermint, honey
- Price: $39
Toxique is the value champ. No fillers, no cheap carrier oils – just pure argan as the base with standardized rosemary, peppermint, and castor extracts. That means rosmarinic acid for possibly blocking scalp DHT, menthol to help aid blood flow, and castor oil for possible density. The optional honey-infused 220ml bottle at $49.99 may be one of the best deals in the category. Honestly, there may not be much that even comes close to this in terms of value.
Potential Pros
- Large volume for the price
- 100% argan base, no cut oils
- Targets hormonal hair loss with rosemary
- May be excellent for dry or damaged hair
- All-natural, cruelty-free, vegan
Cons
Strong natural scent that not everyone will love
Conclusion
With clinical-grade actives and a clean base, Toxique may be the go-to for women wanting faster, thicker growth and stronger ends without filler oils.
3. Mengine Hair & Beard Growth Oil
Best for Men
Form: Oil (60ml)
Key Ingredients: Argan, peppermint, thyme, rosemary, lavender, cedarwood
Price: $29.99
Mengine takes the men’s crown by doubling as both a scalp and beard growth oil. It’s got a potent blend of blood flow boosters and DHT blockers, with zero silicone or fragrance padding it out. The only downside is the smaller bottle – you’ll need frequent top-ups if you’ve got long hair – but for guys juggling early thinning and patchy beards, it might be the best two-in-one solution.
Potential Pros
- Strong blend of anti-inflammatories and follicle stimulants
- Works on both scalp and beard
- Zero fillers, silicones, or synthetic fragrance
- According to manufacturer, it is safe for daily use, even on sensitive skin
Cons
Small bottle runs out quickly for longer hair
Conclusion
Mengine may be the smart pick for men. Whether it’s thickening up the beard or slowing scalp thinning, it could deliver results without unnecessary extras.
4. Kiehl’s Magic Elixir
Best for Fast Pre-Shower Use
- Form: Oil (125ml)
- Key Ingredients: Rosemary leaf oil, avocado oil, safflower oil
- Price: $38
Kiehl’s Magic Elixir is the quick-fix option. It’s designed as a 10-minute pre-shower scalp treatment, so you get the potential stimulation benefits without committing to overnight oiling or long massages. Avocado and safflower give hydration, while rosemary may boost circulation. It’s not loaded with advanced actives, but it may be great for people who want convenience without skipping scalp care.
Potential Pros
- Fast, 10-minute treatment
- May boost scalp circulation quickly
- Hydrating blend with avocado and safflower
- Rinses out easily
Cons
- Not potent enough for serious regrowth
- Contains mild preservatives
Conclusion
For busy people who may want scalp stimulation and hydration without the hassle, Kiehl’s Magic Elixir might just do the job. It’s more maintenance than miracle, but it may work well in a routine.
5. Mielle Rosemary Mint Hair Oil
Best Budget Pick
- Form: Oil (59ml)
- Key Ingredients: Rosemary, mint, biotin
- Price: $9.99
Mielle is the budget gateway into hair oils. At under $10, it may be hard to beat for experimenting with rosemary-based growth. It’s lightweight, includes biotin and mint for possible stimulation, and suits oily hair types. The trade-off is the formula includes silicones and the actives aren’t highly concentrated, so it may be more of a starter product than a long-term solution.
Potential Pros
- Extremely affordable
- Contains biotin and mint for stimulation
- Lightweight and beginner-friendly
Cons
- Has silicones
- Weak concentrations overall
- Not great for long-term regimens
Conclusion
If you’re dipping your toes into hair oils without spending much, Mielle is fine. It won’t transform thinning hair, but it may give you a cheap entry point into scalp oiling.
6. rthvi Revitalize Ayurvedic Oil
Best for Strengthening Damaged Hair
- Form: Oil (60ml)
- Key Ingredients: Amla, bhringraj, rosemary, argan, jojoba, castor
- Price: $34
rthvi’s Revitalize Oil leans into Ayurvedic tradition with a formula aimed more at hair strength than direct follicle regrowth. Amla and bhringraj may strengthen strands, while rosemary and castor could give mild growth support. If your main issue is damage, breakage, or weak lengths, this oil may help preserve what you’ve got.
Potential Pros
- Ayurvedic strengthening blend
- Great for split ends and breakage
- 100% natural and silicone-free
Cons
Less effective for actual regrowth
Conclusion
This one may be best for people with damaged or fragile hair who want to protect and retain length. It’s not a growth powerhouse, but it might keep hair fibers healthier for longer.
7. Titan Groom Beard & Hair Oil
Best for Facial Hair
- Form: Oil (50ml)
- Key Ingredients: Jojoba, coconut, thyme, caffeine
- Price: $29
Titan Groom is built with men’s facial hair in mind. The formula combines caffeine for follicle stimulation with lightweight oils that may not clog pores. It’s scented with cedar and thyme, which gives it more of a grooming vibe than a clinical scalp oil. It’s not the best for full-scale scalp regrowth, but for beard density and daily use, it could be a solid option.
Potential Pros
- Targets beard density
- Caffeine stimulates follicles
- Lightweight, non-greasy
- Subtle natural scent
Cons
Limited impact on scalp regrowth
Conclusion
For guys who care more about their beard than their hairline, Titan Groom may be the pick. It’s practical, light, and beard-focused – more grooming product than hardcore treatment.

Best for Scalp Detox & Hydration
- Form: Oil (60ml)
- Key Ingredients: Aloe, castor, maracuja, açaí, meadowfoam
- Price: $36
Ceremonia blends traditional Latin American botanicals into a scalp-first oil. It’s focused more on detox, hydration, and scalp balance than direct regrowth.

Potential Pros
- Unique botanical blend
- May be good for scalp detox and hydration

Best for Root Strengthening
- Form: Oil (120ml)
- Key Ingredients: Rosemary, grapeseed, jojoba, castor, coconut
- Price: $17
The Mane Choice packs a wide mix of oils and vitamins at a mid-level price point. It may be good for improving root strength and overall scalp condition, though it does include perfume and silicones that may make it less appealing for purists. Still, it’s affordable and accessible.
Potential Pros
- Broad vitamin and oil profile
- May strengthen hair at the root
- Decent price for the size
Cons
- Contains perfume and silicones
- Not ideal for long-term purity-focused users
Conclusion

10. Vegamour Gro Hair Serum Oil
Best for Plant-Based Users
- Form: Oil-Serum Hybrid (30ml)
- Key Ingredients: Mung bean, curcumin, red clover, caffeine, hemp seed oil
- Price: $58
Vegamour’s Gro Oil leans on plant actives and peptides rather than traditional oils.

- Botanical blend for DHT control
- Lightweight, serum-style texture
- Contains caffeine for follicle stimulation

11. Wild Growth Hair Oil
Best for Thickness
- Form: Oil (118ml)
- Key Ingredients: Olive, jojoba, coconut, peppermint, eucalyptus
- Price: $12.99
Wild Growth is a cult classic that’s been around forever – and the formula shows. It’s a heavy, old-school oil with a simple but potent base of olive, jojoba, and coconut, supported by scalp stimulants like peppermint. It’s messy and strongly scented, but it may work for thickness.
Potential Pros
- Large bottle, low cost
- Tried-and-tested formula
- Great for coarse or very dry hair
- May see noticeable thickness improvements with regular use
Cons
- Strong scent
- Heavy, greasy feel
- Not for fine hair
Conclusion
If you want sheer density and don’t mind a heavier formula, Wild Growth may deliver. It’s not elegant, but it may be effective for thickening strands over time.
12. Briogeo B. Well Organic + Cold-Pressed Castor Oil
Best Single-Ingredient Oil
- Form: Oil (30ml)
- Key Ingredient: Castor oil
- Price: $26
Sometimes simple is best. Briogeo’s B. Well is pure cold-pressed castor oil – no blends, no fillers, just the tried-and-true classic for potential growth and thickness. Castor oil is thicker than most oils, so it’s best used sparingly or mixed into a routine rather than slathered on daily.
Potential Pros
- Pure, uncut castor oil
- Rich in ricinoleic acid for growth
- Versatile: scalp, lashes, brows
- Organic and cold-pressed
Cons
- Thick texture, hard to wash out
- No supporting actives for faster results
Conclusion
Briogeo may be the go-to if you want pure castor oil in a premium package. It won’t replace a full blend, but as an add-on for extra thickness, it could work.

- Form: Oil (118ml)
- Key Ingredients: Jamaican black castor oil, shea butter, peppermint, keratin
- Price: $13.99
SheaMoisture’s castor oil blend is built for textured and curly hair. Jamaican black castor oil and shea butter may deliver intense moisture, while peppermint potentially stimulates the scalp.

Potential Pros

- Thick, nourishing blend
- Affordable and widely available
- May strengthen with keratin

Final Thoughts
Hair oils aren’t miracle cures, but the right formula may make a visible difference if you use it consistently. The key is cutting through the hype and avoiding watered-down blends that do more for marketing than your scalp.
- St. Felix may be the most balanced daily option, with clinical-level ingredients in a lightweight base.
- Toxique could give women a high-value, filler-free formula that supports both growth and moisture.
- Mengine may stand out for men thanks to its dual-purpose scalp-and-beard profile.
From there, the rest of the list fills out the niches: quick pre-shower oils, budget picks, heavy-duty Ayurvedic blends, and even beard-specific formulas. No matter your starting point – breakage, early thinning, or just wanting denser, stronger strands – there’s something in this lineup that may fit.
FAQs About Hair Growth Oils
Do hair oils really help hair grow?
They do, but only the right ones. Oils like rosemary, peppermint, and castor contain compounds that may improve scalp circulation or block DHT locally. They don’t create new follicles, but they may help preserve and strengthen existing ones while reducing breakage.
How often should I use a hair oil?
2–3 times per week may ideal for most people. Lighter oils like St. Felix may be used daily, while heavier ones like castor may be best reserved for weekly treatments.
Can I leave hair oil in overnight?
Yes, but it depends on the formula. Lightweight blends absorb easily, while thicker oils may stain pillowcases or clog pores. Always check the brand’s instructions.
Which oil is best for thinning hair?
Rosemary oil has the strongest evidence for slowing thinning, especially when standardized for rosmarinic acid. Blends with peppermint, castor, or DHT blockers (like saw palmetto) also help.
Are hair oils safe for color-treated hair?
Most natural oils may be safe, but avoid blends with silicones or harsh preservatives if you want to protect dyed hair. Lightweight oils like argan and sunflower are especially color-friendly.
What’s the difference between a hair oil and a serum?
Oils are mostly natural extracts, while serums often combine oils with actives like peptides, caffeine, or vitamins in a lighter base. Serums may absorb faster, but both could support growth.
Do men and women need different hair oils?
Not necessarily – the same actives (rosemary, peppermint, castor) may work for everyone. However, men may prefer dual-purpose beard + scalp oils like Mengine, while women may often need more moisture-focused blends like Toxique.
