The Best Hair Growth Oils That Actually Work (+ DIY Recipes You Need to Try)

Maybe you’re grieving a haircut you said yes to when your entire soul was screaming no. Maybe you have curly hair that technically grows an inch a month but shrinks right back, and you are so tired of looking in the mirror and seeing the same length you had in 2022. Or maybe you went through a rough season, stress, a health scare, postpartum, whatever it was, and your hair took the hit, and now you want it back.

Whatever your situation, knowing which hair growth oil actually works is the fastest natural hair growth tip you can act on today, and this post is going to hand it all to you so you don’t have to spend another hour going down a Reddit rabbit hole at midnight.

Every oil here has a specific reason to be in your life, with exact how-tos and zero “you’ll figure it out” energy. Let’s go.

Rosemary Oil: The One With Actual Clinical Receipts

Let’s lead with the overachiever. A 2015 study published in SKINmed Journal compared rosemary oil directly to minoxidil (the active ingredient in Rogaine) for hair regrowth. Result? They performed equally well after six months. The difference? Rosemary users didn’t suffer the itchy, flaky scalp that minoxidil users complained about.

If you’ve been low-key wondering whether your hair fall situation is something to look into more seriously, it might be worth taking this free hair fall quiz before diving into oils so you know exactly what you’re working with.How to use it properly, because just dropping it on your head does nothing:

Mix 5 drops of rosemary essential oil with 1 tablespoon of jojoba or olive oil
Part your hair in sections and apply directly to the scalp, not the lengths
Massage in circular motions for at least 4 minutes (this matters more than you think; more on that below)
Leave on for 30 minutes minimum, or overnight with a shower cap
Wash out with your regular shampoo

Do this 2–3 times a week. Give it 90 days. Take a photo NOW so you can actually witness the glow-up. Find 100% pure rosemary essential oil here and check that it’s not a fragrance blend.

Castor Oil: The Slow Burn That Absolutely Pays Off

Castor oil is thick, sticky, a little dramatic to work with, and one of the most effective hair growth oils that exists.

Its ricinoleic acid content increases circulation to the scalp, blocks the enzyme that can stunt follicle activity, and keeps the scalp environment clean with its antifungal properties.

It’s also the go-to for edges, temple regrowth, and thickness in general.

The mistake most people make: using it straight. Undiluted castor oil is too heavy and can actually cause breakage. Here’s the move:

The castor oil blend that works:

2 tablespoons castor oil (Jamaican black castor oil is the upgraded version)
1 tablespoon argan or sweet almond oil to thin it out
3 drops of peppermint essential oil for an extra circulation kick

Mix, apply to scalp, massage for 5 minutes, leave on for at least an hour or overnight. Use a clarifying shampoo once a week if you’re oiling frequently so buildup doesn’t become your new problem.

Batana Oil: The Underground Oil Everyone’s About to Be Obsessed With

If you haven’t heard of batana oil yet, consider yourself early. It comes from the American oil palm nut and has been used for centuries by the Miskito people of Honduras, a community literally nicknamed “the people of beautiful hair.”

It’s rich in oleic acid, tocopherols, and beta-carotene, all of which nourish the scalp and strengthen the hair shaft from the inside.

What makes it different from most oils: it actually penetrates the shaft rather than just sitting on top of the hair. It’s been linked to reduced breakage and visible regrowth in areas of thinning, which makes it particularly interesting if your hair fall was concentrated in specific spots.

Use it as a pre-wash treatment:

Take a small amount (it’s potent, so less is more)
Warm it between your palms
Apply to scalp and mid-lengths
Leave on for 1–2 hours before washing

Shop batana oil here and look for cold-pressed, unrefined options.

The DIY Hair Growth Oil Recipe You’ll Actually Make Tonight

This is the one. You can order the ingredients right now and have your first batch ready by the weekend. It combines the best hair growth oils into one bottle so you’re not juggling five products or making three different decisions every wash day.

The Sunny Growth Oil (makes one small bottle):

3 tablespoons castor oil
2 tablespoons jojoba oil (it mimics your scalp’s natural sebum, which means it absorbs without clogging)
1 tablespoon argan oil
5 drops rosemary essential oil
4 drops peppermint essential oil (boosts scalp circulation noticeably)
3 drops cedarwood essential oil (wildly underrated; it stimulates follicles and smells incredible)

Pour everything into a dark glass dropper bottle and shake before each use. Light degrades essential oils fast, so skip the clear bottles. Apply directly to scalp 2–3 times a week, ideally at night before bed.

This homemade hair growth oil hits multiple mechanisms at once: stimulating circulation, nourishing follicles, and creating a clean scalp environment for growth.

Onion Oil: Not Cute, But It Works

Yes, onion oil smells. Yes, you will feel like a cauldron witch. But onion oil for hair growth is one of the most researched natural options out there.

A study in the Journal of Dermatology found that applying onion juice to the scalp twice daily for two months led to hair regrowth in 86% of participants.

The active compounds are quercetin and sulfur, both of which feed follicles and improve circulation to the scalp.

How to do it without making your whole apartment smell:

Buy a prepared onion hair oil (many are deodorized and actually pleasant)
Or blend 1 medium onion, strain the juice, mix with 2 tablespoons of coconut oil, apply to scalp
Cover with a shower cap and leave for 30–45 minutes
Wash out with a scented shampoo and feel zero shame

Do this twice a week and pair it with a scalp massage every single time.

The Scalp Massage Secret That Makes Every Oil Work Harder

Here’s something that changes the math on all of this: a 2016 study from Japan found that just 4 minutes of scalp massage daily for 24 weeks significantly increased hair thickness. The participants didn’t even use oil. It was the massage alone doing that.

When you add a hair growth oil to stimulated, circulation-rich follicles, you’re essentially delivering nutrients directly to where they need to go instead of hoping they drift there. It’s the difference between watering dry concrete versus moist soil.

Use a scalp massager tool if your hands get tired, and use it every single time you oil. Four minutes. You can do it while watching The Bear or doomscrolling. No excuses.

Amla Oil: The Ayurvedic Oil for Thickness and Shine

Amla, Indian gooseberry, has been a cornerstone of Ayurvedic hair care for over 3,000 years for a reason.

It’s loaded with Vitamin C, tannins, and fatty acids that reduce premature hair loss and actively promote thick hair growth.

It’s particularly powerful for those dealing with gradual thinning or slow regrowth after a period of hair fall.

It works best as a weekly pre-wash scalp treatment. If you find it too heavy on its own, mix equal parts amla oil with coconut oil before applying. Find amla oil here. Your hair will thank you, and your scalp will genuinely feel different within a few weeks.

Mustard Oil: The Underdog Nobody in the West Is Talking About (Yet)

Mustard oil for hair growth is a staple in South Asian households and has been for generations.

It contains beta-carotene, omega-3 fatty acids, zinc, and antifungal compounds that keep scalp buildup and dandruff in check while actively stimulating follicle activity.

When your scalp is clean and well-circulated, hair grows. It’s not complicated, it’s just chemistry.

Warm it slightly before applying, either a few seconds between your palms or a quick 10-second dip in warm water. Apply to your scalp, leave on for 30–60 minutes, then wash it out. Use it weekly. Shop mustard oil here. Your great-grandmother was right all along.

Consistency Is the Actual Secret Ingredient

None of these oils will do anything if you use them once, take a selfie, see no results in 48 hours, and quit.

The hair growth cycle means that what you do for your scalp today shows up in your hair 2–3 months from now.

The people who get results aren’t the ones with the most expensive products; they’re the ones who showed up twice a week, every week, without drama.

Pick two or three oils from this list.

Make your DIY blend or grab one product.

Commit to a twice-a-week routine.

Take monthly photos so you don’t gaslight yourself into thinking nothing is working.

If you’ve been dealing with a specific concern like thinning or slow regrowth and aren’t sure what’s actually behind it, this free quiz about what’s blocking your hair growth is worth three minutes of your time before you spend money on anything.

That’s the whole system. It just requires you to actually do it.
