Get excited because I have fantastic news for you. Natural, plant based oils really can promote hair loss and encourage hair growth. I’m living proof and have the before and after picture to prove it. In this post I’ll give you 7 oils that have been known and some proven to regrow hair. I will also give you a DIY hair growth serum recipe that is easy to make and easy to use!

DIY Hair Growth Serum

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.

Upon doing research for my latest recipe, my new & improved brow serum, I realized there were so many natural oils that had hair re-growth capabilities.  I personally am not experiencing thinning hair on my scalp but I can only imagine how disheartening it is and how a natural solution would be so amazing.  

I’ve compiled 7 oils that promote hair growth + a DIY Hair Growth Serum recipe to help you on your journey to thicken, strengthen and regrow hair. 

First, let me list some causes of hair loss.  If we don’t identify and treat the root cause, the chances of prolonged re-growth are greatly reduced.

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 circulations which in turn wakes up hair follicles.  Circulation is key when it comes to hair growth.  Rosemary also increases cellular metabolism.

Hazelnut oil is full of fatty acids, proteins, and vitamins, which can nourish your 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!

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.

DIY Hair Growth Serum

3 TBSP. Black Cumin Seed Oil (find it HERE)

1 TBSP. Hazelnut Oil (find it HERE)

2 TBSP. Castor Oil (find it HERE)

1.5 TBSP. Jojoba Oil (find it HERE)

30 drops Cedarwood Essential Oil (find it HERE)

20 drops Rosemary Essential Oil (find it HERE)

10 drops Lavender Essential Oil (find it HERE)

How to Use:

  • 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.
  • I suggest using 10 drops in the palm of your hand, then massaging all over the scalp, paying closer attention to thinner areas.
  • Massage as long as you have time because massage also promotes blood flow.
  • Leave the oil treatment on your scalp for at least 15 minutes.
  • After the oil has set on the scalp, shampoo your hair.  *If shampoo is not removing the oils enough, massage conditioner into your scalp before you get into the shower.
  • 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.  Plus, shampooing out in the morning will be more effective.
  • Use once daily for at least 3 mos.  Results vary from person to person.

I used a 4 ounce dropper bottle for this recipe.  You can find one HERE.  Also, a small funnel is helpful.  If you’d like, you could easily cut this recipe in half.

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.  

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 usual 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.  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 those of you who have oily scalp, 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 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.
