From family recipes passed down through generations to simple two-ingredient blends shared online, people are constantly experimenting in hopes of growing longer, healthier hair without spending a fortune.
But with so many recipes using different oils and essential oils, it can be difficult to know which ingredients are actually worth trying and which are simply popular trends.
This blog breaks everything down in one place.
You’ll learn which DIY hair growth oil suits different hair types, how to mix your own blend, use it the right way, and what results to realistically expect.
Does DIY Hair Growth Oil Actually Work?
Home oil blends can help your scalp and make your hair look stronger. But they won’t reverse pattern hair loss or regrow hair lost to conditions like alopecia areata.
The American Academy of Dermatology (AAD) notes that how you care for your hair matters, and the right care can prevent certain types of hair loss and leave hair looking healthy.
That’s different from treating a medical form of hair loss.
There’s a real gap between “healthy growth” and “hair loss reversal.” Healthy growth means your hair works better. You get less breakage.
Reversing hair loss means growing hair back where follicles have shrunk or stopped working. That usually needs a prescription treatment or a dermatologist’s help.
Best Carrier Oils for DIY Hair Growth Oil
Carrier oils form the base of your blend. They dilute strong essential oils and coat each strand of hair. Here’s how the most common picks compare.
| Oil | Benefits | Best For | Possible Drawbacks |
|---|---|---|---|
| Coconut Oil | Soaks in fast, cuts protein loss | Fine to medium hair, pre-wash care | Can feel heavy, may worsen dandruff |
| Castor Oil | Rich in fatty acids, locks in moisture | Dry ends, brows, lashes | Sticky, needs a second shampoo to rinse |
| Jojoba Oil | Matches natural scalp oil, absorbs easily | Oily or acne-prone scalps | Pricier than most carrier oils |
| Argan Oil | Light, smooths frizz, adds shine | Dry, frizzy, or color-treated hair | Too light for very dry or coily hair alone |
| Sweet Almond Oil | Softens strands, eases dry scalp itch | Sensitive or dry scalps | Skip if allergic to tree nuts |
| Olive Oil | Moisturizes shaft, calms irritation | Thick or coarse hair | Can leave hair flat if overused |
Essential Oils to Add to Your Carrier Oil
Once you’ve picked a carrier oil, essential oils add the extra benefits, like scalp stimulation or a calming effect.
- Rosemary: Studies show it may help boost blood flow to the scalp.
- Peppermint: Gives a cooling, tingly feel. That signals more blood flow to the area.
- Lavender: Eases stress-related tension. It also showed support for hair growth in animal studies.
- Cedarwood: Helps balance oil production. It also fights fungus that can affect scalp health.
- Tea tree: Used for dandruff and flaking.
Easy DIY Hair Growth Oil Recipe
Each recipe here makes about one ounce, enough for four to six uses. Pick the one that matches your hair or scalp needs.
1. Classic Rosemary Growth Oil
This is the all-purpose blend most people start with: simple, cheap to make, and gentle enough for regular use.
Ingredients: 2 tablespoons of jojoba oil, 1 tablespoon of castor oil, 5 drops of rosemary essential oil, and 3 drops of peppermint essential oil.
Steps:
- Measure the jojoba oil and castor oil into your bowl.
- Add the rosemary and peppermint essential oils.
- Stir gently until fully mixed.
- Pour into your glass bottle using the funnel.
- Label the bottle with the date.
If you enjoy mixing your own hair treatments, try a homemade hair mask on the weeks between oiling.
2. Lightweight Oil for Oily Scalp or Fine Hair
This version skips heavy oils, so it won’t weigh hair down or add extra shine to an already oily scalp.

Steps:
- Measure the jojoba oil and grapeseed oil into your bowl.
- Add the rosemary and tea tree essential oils.
- Stir gently until fully mixed.
- Pour into your glass bottle using the funnel.
- Label the bottle with the date.
3. Deep Moisture Blend for Dry or Coily Hair
This blend uses heavier oils that coat the strand and lock in moisture, which works well for dry, thick, or coily hair.
Ingredients: 2 tablespoons coconut oil, 1 tablespoon castor oil, 1 teaspoon olive oil, 5 drops rosemary essential oil, and 3 drops lavender essential oil.
Steps:
- Measure the coconut, castor, and olive oil into your bowl.
- Add the rosemary and lavender essential oils.
- Stir gently until fully mixed.
- Pour into your glass bottle using the funnel.
- Label the bottle with the date.
4. Scalp Treatment for Dandruff and Flaking
This blend leans on tea tree and cedarwood for their antifungal properties, which can help with a flaky or itchy scalp.
Ingredients: 2 tablespoons jojoba oil, 1 tablespoon castor oil, 4 drops of tea tree essential oil, and 3 drops of cedarwood essential oil.
Steps:
- Measure the jojoba oil and castor oil into your bowl.

- Stir gently until fully mixed.
- Pour into your glass bottle using the funnel.
- Label the bottle with the date.

How to Use DIY Hair Growth Oil the Right Way?
Using hair oil the right way helps it reach the scalp without leaving the hair overly greasy. The amount, massage time, treatment length, and washing method can all affect the final result.
- How much to apply: Start with about a teaspoon for shoulder-length hair. Focus on the scalp, not just the strands.
- How to massage the scalp: Use your fingertips, not your nails. Make small circles from the hairline to the crown for 3 to 5 minutes.
- How long to leave it on: Thirty minutes is enough for most oils to soak in.
- Overnight vs. short treatment: An overnight treatment works well for a very dry scalp. Wrap your hair in an old towel or shower cap to protect your pillow.
- How often to use: Try two to three times a week to start. Daily use can lead to buildup for most people.
- When to wash it out: Shampoo it out the same day or the next morning. Use a clarifying shampoo if the oil feels hard to remove.
Which Hair Growth Oil Is Best for Your Hair Type?
Different hair types respond to different oil textures.
The same logic that separates wavy or curly hair applies here: match the oil to your scalp and strands for moisture and shine without buildup or weighed-down hair.
| Hair Type | Best Oil Choices | Why it Works |
|---|---|---|
| Dry Hair | Castor, olive, avocado | Heavier oils seal in moisture and cut breakage |
| Oily Scalp | Jojoba, argan | Light oils balance oil production without adding grease |
| Fine Hair | Argan, grapeseed | Thin oils add shine without weighing hair down |
| Thick Hair | Coconut, castor, olive | Richer oils soak into dense strands better |
| Curly and Coily Hair | Castor, jojoba, coconut | Coats and seals the cuticle, cutting down on frizz |
| Color-Treated Hair | Argan, jojoba | Gentle oils won’t strip color or dry out treated strands |
Mistakes that Slow Down Hair Growth Oil Results
Hair oil works best as part of a balanced hair care routine. Even a good blend won’t work well if it’s applied the wrong way.
- Using Too Much Essential Oil: A heavy hand with rosemary or peppermint can irritate the scalp rather than help it.
- Applying to a Dirty Scalp Every Time: Oil layered over days of buildup traps dirt against the follicle instead of Feeding It.
- Expecting Overnight Growth: Hair grows about half an inch a month. Real change takes several oiling cycles, not one weekend.
- Being Inconsistent: Skipping weeks at a time undoes the progress your scalp was making.
- Skipping Patch Testing: Test a small patch on your inner arm first. Wait 24 hours before using on your scalp. This catches allergic reactions early.
- Leaving Oil on Too Long: More than a day or two invites buildup and clogged follicles instead of better results.
- Using Oils that Don’t Suit Your Scalp: Heavy oils on an oily scalp can worsen shedding and flaking.
Real Experiences with DIY Hair Growth Oil
Here’s what people in DIY hair care communities on Reddit say about mixing their own oil blends.
1. Combining Carrier Oils With Rosemary
A poster in the r/longhair community asked other users what formula they mix at home and what’s actually helped their hair the most. One reply suggested starting with a carrier oil like batana, castor, or jojoba, then adding rosemary to support growth.
2. Looking for a Measured Recipe
Someone in r/essentialoils had jojoba, coconut, castor, rosemary, lavender, and chamomile oils on hand but couldn’t find a recipe with real measurements. They wanted to mix a full bottle they could use regularly instead of guessing ratios each time.
3. Making Hair Oil to Cut Costs
A user in r/Naturalhair shared a jar of hair oil they made at home to avoid buying hair growth serums. They planned to mix it into shea butter later and asked how long a homemade batch lasts before it starts to mold, letting theirs sit for about four weeks.
4. Avoiding Silicone Buildup
A member of r/DIYBeauty wanted a lightweight sealant oil similar to a Moroccanoil treatment, but without the silicone buildup. They asked how to combine “no buildup” silicones into a featherweight recipe, since some natural alternatives weren’t easy to find where they lived.
5. Skipping the Double Boiler
In r/ZeroWaste, someone wanted to mix rosemary essential oil with a carrier oil but didn’t want to buy a double boiler for one bottle. They asked if shaking the oils together in a dropper bottle works as well as heating them, since keeping the process low-waste mattered more to them than following the standard method.
Other Habits to Adopt Which Support Healthy Hair Growth
Making your own hair oil blend lets you choose ingredients that suit your scalp, hair type, and routine. Start with a simple recipe, use clean tools, and test a small amount before applying it across your scalp.
- Eat Enough Protein: Hair is built mostly from a protein called keratin. Low protein intake can show up as weaker strands within a few months.
- Get Enough Iron and Vitamin D: Both play a role in the hair growth cycle. A shortage of either is a common, fixable cause of shedding.
- Reduce Heat Styling: Frequent blow-drying or flat-ironing weakens the hair shaft over time. That adds to breakage that oil alone can’t fix.
- Avoid Overly Tight Hairstyles: Constant pulling from tight ponytails or braids can cause hair loss at the hairline, called traction alopecia.
- Protect Hair While Sleeping: A silk or satin pillowcase reduces friction that causes breakage overnight.
- Manage Stress: Chronic stress can push more hairs into the shedding phase. Dermatologists call this pattern telogen effluvium.
- Trim Split Ends Regularly: A trim every 8 to 12 weeks prevents splits from traveling up the shaft and causing further damage.
Final Thoughts
The best DIY hair growth oil isn’t the one with the longest ingredient list; it’s the one you’ll use consistently, and that suits your hair and scalp.
A simple, well-balanced blend, paired with gentle scalp massage and healthy hair care habits, can help reduce breakage, improve shine, and support stronger-looking hair over time.
Start with a small batch, pay attention to how your scalp responds, and adjust your recipe as needed rather than chasing every new trend.
Homemade oils work best as part of a long-term routine, not as an overnight fix.
