I think all of us know someone struggling with thinning hair or baldness or struggled ourselves at some point in time. If you’ve ever had a baby, you know how frustrating postpartum hair loss can be. I recently found out that hair loss is also a repercussion of a high fever typically from a virus. Lord knows most of us have had a virus lately!

Upon doing research for my latest recipe, my new & improved brow serum, I realized there were so many natural ingredients that had hair re-growth capabilities that don’t include coconut oil or olive oil. I personally am not experiencing thinning hair at the moment however I have shed copious amounts of hair after two bouts with Covid as well as 2 pregnancies that took a major toll on my hair. These 4 different instances have inspired me to explore the possibility of an all natural DIY that could help.

I understand how disheartening it is and how a natural diy hair oil that worked would be so amazing. 

My DIY hair growth oil is stimulating, deeply moisturizing, smells amazing, and takes minutes to make. This homemade hair regrowth oil is perfect for restoring dry, damaged hair, nourishing the scalp and waking up the hair follicles to encourage new growth. It can be used from root to tip as a conditioning hair oil but also and more importantly should be massaged into the scalp. 

This DIY hair growth oil works well for all hair types. Whether you have thin, fine hair or thick, course hair, everyone could use a natural hair oil to revitalize their strands, balance the scalp and encourage blood flow.

Where blood flows, healing and healthy function can happen.

First, I’ve compiled 7 natural, plant based oils that promote hair growth. I explain why they’re effective as well as provide you with several popular studies that have proven that they work. 

What are some causes of hair loss? It is so important to identify and treat the root cause of thinning hair. The chances of prolonged re-growth are greatly reduced if you don’t acknowledge where the issue is coming from.

Possible Hair Loss Causes

  • Emotional stress
  • Physical stress
  • Postpartum
  • Menopause
  • Hormone imbalance
  • Thyroid issues
  • High Blood Pressure
  • Exposure to toxins
  • Extreme weight loss
  • Vitamin & mineral deficiencies
  • Allergies
  • Heredity
  • High Fever
  • Side effects of prescription drugs

7 Oils That Promote Hair Growth:

Black Cumin Seed Oil Not only does this oil strengthen hair, it addresses hair loss. No one quite understands why it happens, but it most likely has something to do with its powerful antioxidant and antimicrobial properties. Strengthening hair follicles will in turn cause healthier hair growth. There have been MANY studies showing just how effective this oil has been.

Castor Oil is probably the most well-known and most-used oil when it comes to regrowing hair. Because of castor oil’s high concentration of ricinoleic acid, it is great for increasing circulation. By massaging it into the scalp, increased blood flow will occur, insuring delivery of nutrients to hair follicles. The antioxidants in castor oil also support the keratin in hair and help make hair stronger and smoother.

Cedarwood Essential Oil is an extremely important ingredient when re-growing hair. Study after study prove cedarwood oil (usually mixed with jojoba oil) is very effective when it comes to re-growing hair.  

Rosemary Essential Oil stimulates blood circulation which in turn wakes up the hair shaft. Circulation is key when it comes to hair growth. Rosemary also increases cellular metabolism. Plus, rosemary oil has anti-fungal properties as well as antibacterial properties.

Hazelnut oil is full of essential fatty acids, proteins, and vitamins, which can nourish dry hair along with the scalp. It is a great oil for maintaining good hair growth and ideal for stimulating the hair follicles and nourishing them to alleviate dry scalp. As a side note, hazelnut oil is also great at preserving your hair color.

Clary Sage Essential Oil is very stimulating to hair follicles, encouraging hair growth. It also helps balance scalp oils. I’m not sure if it can help balance hormones by applying to your scalp, but it is known as the most effective essential oil for regulating hormones! It also has powerful anti-inflammatory properties.

Jojoba Oil is said to stimulate hair growth. Jojoba also cleanses the scalp of excess sebum build-up which can clog hair follicles. Also, jojoba oil stimulates circulation on your scalp, bringing blood flow to your hair follicles and encouraging growth.

What You’ll Need to Make DIY Hair Growth Oil

DIY Hair Growth Serum

DIY Hair Growth Oil

Yield: 4 ounces
Prep Time: 5 minutes
Total Time: 5 minutes

This super easy DIY hair growth oil is simply a powerful combination of scientifically tested plant based oils that have been successful at encouraging hair regrowth. This oil is meant to be applied to the scalp in order to improve scalp health and hair follicle health by encouraging increased blood circulation, follicle detox and overal conditioning of the hair and scalp.


  • 3 TBSP. Black Cumin Seed Oil
  • 1 TBSP. Hazelnut Oil
  • 2 TBSP. Castor Oil
  • 1.5 TBSP. Jojoba Oil
  • 30 drops Cedarwood Essential Oil
  • 20 drops Rosemary Essential Oil
  • 10 drops Lavender Essential Oil


  • 4 ounce glass dropper bottle
  • Small Funnel


How to Use:

  1. In order to get the most out of this serum, it must be massaged into the scalp and left on for a period of time.
  2. I suggest using 10 drops in the palm of your hand, then massaging all over the scalp, paying closer attention to thinner areas.
  3. Massage as long as you have time because massage also promotes blood flow.
  4. Leave the oil treatment on your scalp for at least 15 minutes.
  5. After the oil has set on the scalp, if you feel it necessary, shampoo your hair. However, shampooing is not necessary if you are not experiencing greasy hair. These oils are able to set on the scalp as a face oil or mositurizer would set on the face. 
  6. I personally suggest using this serum before bed and leaving it on all night.  This will encourage the oils to penetrate deeper and more thoroughly.
  7. Use once daily for at least 3 mos.  Results vary from person to person 


I used a 4 ounce dropper bottle for this recipe.  Also, a small funnel is helpful.

Benefits of Using this DIY Hair Growth Serum

  • Nourishes the scalp
  • Relieves dandruff
  • Strengthens hair
  • Conditions hair
  • Increases shine

A Few Hair Growth Studies…

If you’re experiencing thinning hair, I really encourage you to try this recipe out.  I couldn’t get over all the studies where people were using cedarwood essential oil or black cumin seed oil and seeing great improvement that rivaled a prescription treatment.

Funny enough-there are no studies showing castor oil effective for hair loss. However, many, many people have reported an increase in hair when using it on a regular basis, myself included. 

This study shows how effective the essential oils cedar wood, rosemary, lavender and thyme are with regrowing hair from alopecia.

According to this study, rosemary oil performed as well as minoxidil, a common hair growth treatment, but with less scalp itching as a side effect.

Black Cumin Seed Oil proved 76% effective in reducing hair loss in this study.

This study showed that 70% of people found an increase in hair density and strength after using black cumin seed oil.

My Personal Experience:

I have been using a roll on version of this DIY hair growth serum for my eye brows. Within 1 month, I experienced a noticeable difference in my brows. The change is easy to see and I couldn’t be more thrilled! Try this serum. I believe you will see improvement minus the side effects! In fact, I sell it HERE in my Etsy shop.

The Importance of Ingredient Quality:

Of course, you must choose high quality oils in order to create an effective DIY.  I got all my oils from Mountain Rose Herbs for this DIY.  While it might be pricey up front, if this works-it’s so worth it.  If it’s not effective for you, all these oils can be used in plenty other amazing DIYs!  

Plus, these oils are very healthy for your whole head of hair.  Your hair from root to tip can benefit from the conditioning and strengthening qualities of this recipe. In fact, you should check out my Hair Strengthening Oil for Color Treated Hair-it’s one of my most used DIYs to date and I love adding cedarwood to it.

For essential oils I go back and forth from Mountain Rose Herbs and Plant Therapy. I love them both however, Plant Therapy has free shipping and lower prices.

Many of us love Amazon’s quick free shipping so I created an Amazon shop where I recommend only the ingredients I have tried and can vouch for. Visit my Amazon storefront HERE.

For those of you who struggle with limp, greasy hair, like me-I created a Hair Growth Spritzer that is water based but contains the essential oils we talked about today. It smells wonderful and you simply spray it on your scalp morning and night! However, if you are desperate for quick results, I would give this recipe a go because I believe black cumin seed oil is a powerhouse hair growth oil.

  1. Hello,
    I was looking at this again and noticed you mention clary sage in the article but you didn’t mention it in the recipe. Is this correct?
    Thank you,

    1. Kerry-Yes, I actually hate the smell of clary sage so I nixed it. I believe what I did add is effective enough but if you’d like to add it, I would smell it first then add anywhere from 3-10 drops.

      1. Hello you posted this as scientifically proven and tested, I was wondering what studies you’re referencing? Not trying to be rude just wanting to read up on the same as you did.

  5. Hi there. I was wondering if I could somehow doctor this recipe (perhaps with less essential oils) for my eye lashes. I’m 8 weeks postpartum and with both of my babies I lost a lot of the thickness and length of my lashes. Thank you!

    1. Hi Cassandra-I’m not sure because some people can take essential oils around the eyes without any irritation. I am not one of them so I have no idea how much to say. I do have a lash serum recipe HERE though!

  6. Hi Jenni

    I was diagnosed with multiple sclerosis and have thinning hair. There is a lot of breakage due to dryness. I hydrate a lot and supplement with omega 3. Is there a DIY serum that I could put into my hair and use it as a leave-in? Any help would be appreciated!

    Thank you.

  7. Hello – thanks for the great recipes. MRH’s hazelnut oil is out of stuck. Do you have another trusted source to replace it? I checked Sparks Naturals but they didn’t have it. I have been under a lot of stress recently and have lost a lot of hair and would love to try this recipe to feel better. Thanks in advance!

    1. Mina-Shoot! I hate when that happens! I do like Plant Therapy and they can be found on Amazon. I just checked and you can find it HERE. Good luck-maybe your hair loss is from summertime? I loose so much hair when the weather gets hot and it’s pretty normal. But you’re right-stress wreaks havoc on so many functions of the body-good luck and I hope your stress will lessen soon!! Thanks!!

  8. HI Jenni,

    Would this work for female or male-pattern balness?

    I started using black seed and castor oil together, mixing the two according to what I read on multiple sites: 1 1/2 T. black seed oil and 1/2 T. castor oil. I used about half of the blend in one shot (the first time I left it in for about an hour, the 2nd time 30 minutes)and oddly enough, it seemed that within days of doing it, my bald spots were bigger and my “parts” wider. A couple of times I did put some black seed oil directly on the scalp. Is it possible that this drastic result happened because I didn’t add anything else to the mix and on their own, it was too much of these oils?

    1. Claudia-I’m at a loss-I have no idea if these 2 ingredients could make things worse. I’m thinking you personally just don’t respond to these oils in the typical way. I’m sorry to be no help on this. I just can’t imagine!! Best of luck in finding a solution.

  9. Hi there-

    Thank you for this information. Is this mixture something that takes months to notice and, if so, do you know if it really does work? I use mountain rose herbs and like them very much. I will have to purchase a few more of the ones you suggested.

  10. Hello! I am planning to try this serum recipe for some significant hair loss. Would sweet almond oil be an acceptable substitute for the hazelnut oil?

    1. Hi Kelly-Unfortunately it would not. Hazelnut has particular properties to help stimulate hair follicles. Sweet Almond Oil is nourishing but it doesn’t have properties to help with hair growth. I’m sorry your dealing with hair loss-best of luck!

  11. I have found 3 Oils that women in India use regularly for their hair. I believe they work because I have never seen an Indian Woman with thin fine hair, have you?
    The oils are: Amla, Bhringraj and Brahmi oils, which I would replace for the hazelnut and jojoba oils (jojoba is actually a wax, not an oil)

    I use these three along with Castor oil and now have added Black Cumin Seed oil as well to my hair oil recipe along with the essential oils mentioned. (including peppermint)

    Also, Peppermint E.O. is good for stimulating Follicle growth.

    Question: in the two photos you have of before and after, in the bottom it appears that you are wearing mascara. If so, it would have been better to see actual growth by having identical situations for comparison: no mascara in either.

    I have been under severe stress for several years and am actually now being treated by a Naturopathic doctor for stress and adrenal and now thyroid issues.

    My brows have almost completely disappeared and my
    lashes are short and have gone ‘naturally’ blond. I have used oils on my brows for a long time with little to no results. Hoping adding in day AND nighttime applications as well as Black Cumin Seed oil will help.

    Thank you for the recipe

    1. Carol-Best of luck-I too am working on my adrenals and thyroid. Just to be clear-I don’t use my brow serum on my lashes which is why I didn’t mind wearing mascara in the after photo. I have yet to find a gentle recipe that my eyes can handle and not burn. Would love to be able to use essential oils for lash growth but it’s just too risky. Thank you for reading and commenting!!

    2. Hi, Carol. I was just curious if you’re experiencing any positive (re-growth) results with the oils you mention? Stress has me at a disadvantage with my tresses as well – I think I was also suffering from adrenal drain, but I never sought the help of a practitioner, but have gone coffee-free finally (first time in 40 years). Unfortunately, there are other factors in our environment that are very difficult for us to control (EMF’s for one), that can contribute to our overall health, including the health of our scalp/hair.

  12. I so wish you sold this in your Etsy shop! I used this years ago when you first posted the recipe and loved the effect it had on my hair! I just don’t know if I can put out the expense to buy all the individual ingredients to make it. I struggle to use up all the ingredients before they go bad. Hate wasting them and the money!

    1. Katie-I just double checked and I’m out of black cumin seed and caster oil. Otherwise I could make it. Perhaps I’ll think about selling it. I’m glad to hear you liked it! Thank you!

  13. Hi Jenni,
    I am so glad I came across your recipe. About a year ago I was diagnosed with Hashimoto and over the year my hair has fallen out in handfulls. I have tried some things but nothing even the meds I’m on are helping. I am going to try your recipe and also the one for brows as mine are almost gone too. Thank you for the information about these recipes. Mary

  14. Hi Jenni,
    I hope you consider making this hair growth serum and selling on your site. I think this might help or I’m very hopeful. I started losing my hair by the hands full a year and a half ago when I found out I had cancer. When I started chemo is when the hair started coming out. I would love to try this so I could show the other ladies there is hope to possibly get their hair back. If you could share the sites that carry the oils for purchase or your site if you would sell.
    Bless you & thank you

    1. Hi Patty-I’m sorry you’re going through cancer. I hope you’ve had success with getting treated. I have backed off of my Etsy shop some and simplified what I sale due to life getting too busy. I do link all the oils I mention in the article. I believe the linked items are in pink. When in doubt-I always recommend Mountain Rose Herbs. They have the best quality oils and a large selection. Their pricing is very fair as well.

  15. Hi Jenni,
    I’ve been reading up on EO’s for hair growth and a couple I’ve seen come up several times are Sandalwood and Orange. Sandalwood: has a unique ability to trigger the main building block of the protein keratin. Orange: stimulates blood flow and is rich in Vitamin C and B, fundamental to building collagen and keratin.
    Would these be a possible add in or sub for the ones you recommended? I only wash my hair once a week and since I work in the hospitality industry, I would like a scent profile that would be pleasing. I was thinking, lavender, orange and sandalwood.
    Any input would be appreciated, thanks 😊
