DIY Natural Brow Growth Serum

Let’s just cut to the chase here: when I was in high school, I totally over-plucked my eyebrows. I went to school in the 90’s and early 2000’s, a time when Jennifer Aniston and Kate Moss had their perfectly plucked brows all over TV and magazines. I believed plucking your eyebrows was just something you had to do to be beautiful, along the lines of shaving your legs or filing your nails.

These beliefs of mine have since shifted, not least of all the one about my brows. Thankfully, I discovered a few natural ingredients that help restore hair growth, and since I’ve been using it I’ve noticed that eyebrow hairs I thought were gone forever have started cropping back up again. So today I wanted to share my recipe for this all natural brow growth serum with you!

DIY Natural Brow Growth Serum

It’s a pretty simple recipe with only three natural ingredients. I should note first that this serum will not make new hairs grow where there were never hairs before. It’s not magic! But, if you’re like me and plucked your brows a little too heavily in your teenage years, this might just be able to help them grow back.


  • Castor oil
  • Aloe vera gel (preferably fresh)
  • Rosemary essential oil (optional)


DIY Natural Brow Growth Serum

Mix equal parts castor oil and aloe vera gel in a re-usable pot or jar. Castor oil can be purchased from most health food stores or online. For aloe vera, it’s best if you harvest it fresh from an actual aloe plant. Investing in an aloe plant isn’t a bad idea because the gel has lots of uses, and it also makes a cute accent in your home! I’m not sure how effective store-bought aloe gel would be for this recipe.

To prepare the gel, trim off a section of the plant. Use a knife to carefully slice off the spiky edges and then to peel off one flat side of the leaf. From there you can use the knife to gently scrape the gel from the middle into your jar.

After that, I like to add just a few drops of rosemary essential oil. This gives the serum a nice scent and also has some added restorative benefits when it comes to your hair follicles.

Apply the serum every night before bed. Using a Q-tip, swirl the serum around to make sure it’s mixed well, then smooth it over your brows and the surrounding skin, making sure to cover any sparser areas. After it’s applied, you can leave it as-is or massage it into the skin using your fingertips for better absorption.

As always, it’s best to do a test patch on your skin 24 hours before the first time you use the serum to make sure your skin won’t react badly to any of the ingredients.

How it works

Castor oil contains fatty acids and Vitamin E which helps strengthen hair. Its high ricinoleic acid content “combined with the omega-6 and 9 fatty acids, penetrates the hair shafts and roots and nourishes it, restoring its optimum health and boosting hair growth” (source). It also helps with increasing circulation which will help stimulate hair growth (source).

Similarly, aloe vera gel works in two ways. Firstly, it contains vitamins which promote healthy hair and keep it from falling out. It can also increase blood circulation to the area, which can slow hair loss and promote growth (source).

Finally, rosemary oil again stimulates circulation, increasing blood flow to the area and promoting cell turnover which helps prevent hair loss (source).
