Best oils for hair growth — I’ve searched that exact phrase more times than I can count.
If you’re here, I’m guessing you’ve done the same.
Maybe your hair feels thinner than before.
Maybe you see more strands on your pillow.
Or maybe you just want thicker, healthier hair naturally.
Let me tell you something honestly — the best oils for hair growth are not magic potions. They won’t turn you into Rapunzel in 7 days. But when you use the right natural oils for hair growth consistently, they do improve scalp health, reduce breakage, and help your hair grow stronger over time.
And that’s exactly what we want — stronger roots, less hair fall, thicker-looking hair.
Let’s break it down properly.

Why Oils Help (But Aren’t Miracles)
Before we jump into the best oils for hair growth, let’s set expectations.
Hair grows from the scalp. If your scalp is dry, inflamed, or poorly nourished, your hair won’t thrive.
Oils help by:
- Improving scalp hydration
- Reducing protein loss
- Supporting blood circulation
- Protecting hair from breakage
- Adding shine and softness
But — and this is important — oils don’t fix hormonal hair loss or medical conditions. If you notice sudden or extreme hair fall, please see a dermatologist.
Now, let’s talk about what actually works.
1️⃣ Rosemary Oil for Hair Growth 🌿

If there’s one oil that dominates every conversation about the best oils for hair growth, it’s rosemary oil for hair growth.
I was skeptical at first. Another internet trend? Maybe.
But here’s what changed my mind.
A 2015 study published in Skinmed Journal compared rosemary oil to minoxidil (a common hair growth treatment). After 6 months, both groups saw similar improvement in hair count — but rosemary had fewer side effects.
That caught my attention.
Why I Like It
- May improve scalp blood circulation
- Supports healthier follicles
- Reduces itchiness
But please — never apply it directly.
It’s an essential oil. Always mix 3–4 drops with a carrier oil like coconut oil before applying.
How I use rosemary oil for hair growth:
- Mix 3 drops with 2 tablespoons coconut oil
- Massage into scalp for 5–10 minutes
- Leave for 1 hour
- Wash gently
I do this twice a week. Slowly, my hair shedding reduced.
Not overnight. But steadily.
2️⃣ Coconut Oil for Hair Fall 🥥

If you grew up in India like I did, coconut oil was part of childhood.
Sunday = oil massage day.
And guess what? Science supports it.
Studies show coconut oil for hair fall works because it reduces protein loss in both damaged and undamaged hair. That’s huge. Hair is made of protein (keratin), and when it loses protein, it becomes weak and breaks.
Why Coconut Oil Is One of the Best Oils for Hair Growth
- Penetrates hair shaft deeply
- Reduces breakage
- Prevents dryness
- Strengthens strands
It doesn’t regrow lost hair. Let’s be honest.
But less breakage = thicker-looking hair.
When my hair felt rough and brittle last summer, coconut oil brought it back to life.
Sometimes the simplest natural oils for hair growth are the best.

3️⃣ Castor Oil for Hair Growth 💧
Okay. Let’s talk about the thickest oil on earth.
Castor oil for hair growth feels like honey. Heavy. Sticky. Hard to wash.
So why use it?
Because it’s rich in ricinoleic acid, which may support scalp circulation and moisture retention.
When I started using castor oil for hair growth, I mixed it with coconut oil. Otherwise? Impossible to apply.
Benefits I Noticed
- Hair looked fuller
- Extra shine
- Less scalp dryness
But here’s the truth — there’s limited scientific proof that castor oil directly grows hair. It mainly improves scalp condition and reduces breakage.
Still, when used properly, it’s one of the popular oils for thick hair naturally.
4️⃣ Argan Oil Benefits for Hair ✨
Now let’s talk about luxury.
Argan oil benefits for hair are mostly about smoothing and protection.
It’s rich in vitamin E and antioxidants. Unlike castor oil, it’s lightweight. Perfect if you hate greasy hair.
I use argan oil after washing my hair — just 2 drops on damp hair.
What It Does
- Controls frizz
- Adds shine
- Reduces breakage
- Makes hair manageable
It doesn’t directly boost growth, but preventing breakage supports longer hair over time.
That’s why it still deserves a place among the best oils for hair growth routines.
How to Use Oil for Hair Growth (The Right Way) 🧴
Using oil properly matters more than which oil you choose.
Here’s exactly how to use oil for hair growth:
✔ Always dilute essential oils
✔ Massage gently (don’t scratch your scalp)
✔ Apply 1–2 times per week
✔ Leave for 1–2 hours (overnight if mild oil)
✔ Wash with mild shampoo
Consistency beats quantity.
More oil doesn’t mean more growth.
When I over-oiled my hair, my scalp felt greasy and itchy. Lesson learned.
