DIY Brow Growth Serum on Steroids!

Jump to Recipe

DIY Brow Growth SerumQuite a while ago I shared a DIY eyebrow growth serum.  It was a pretty common recipe that contained castor oil and rosemary oil.  I’ve recently been doing research on natural ingredients that help with hair growth and decided to add a few to my original recipe and see if it works. WELL-it works. It works really well! I no longer am budgeting microblading. My bald spots have filled in and I have hair where I normally don’t grow any! In fact, I’m so in love with this serum that I’m not selling it! 

Hair Growth Ingredients:

This brow serum contains more ingredients then the original but is so easy to make.  Two ingredients that have major hair growing power are Black Cumin Seed Oil and Cedarwood Essential Oil.  

According to Dr. Axe, one of the most interesting black cumin seed oil benefits is its uncanny ability to help restore hair loss most likely due to it’s powerful antioxidant and antimicrobial properties.  When you strengthen hair follicles, strengthened roots are inevitable.  

Cedarwood essential oil can stimulate the hair follicles and increase circulation to the scalp.  Used along with rosemary and lavender essential oils, hair growth was improved in 44% of people over time according to THIS study.

Please note that with natural ingredients, you must be consistent and sometimes it takes up to a minimum of 6 months before seeing results.  I will say that many people experience obvious hair growth within weeks of consistently using DIY serums.  I personally could tell a difference after a week.

You’ll need a roll-on bottle or a mascara bottle as well as a small funnel.  Because a roll-on bottle is so small, I did not measure the exact amount of oils I used.  I find it’s way better to make a visual recipe where you can see how much is needed.  Hope that works well for you!DIY Brow Growth Serum

To Use:

Apply this serum directly to the brows in the evening after your skin care routine.  For best results, apply morning and night if you are able to wear the serum through out the day.

It only takes a couple swipes per brow.  Be very careful not to get this serum in your eyes.  It will sting.  Less is more!

I mentioned earlier that I am no longer planning to have my eyebrows microbladed. I’ve found that all I need is this serum and a monthly brow dye. I do the dye myself. It makes the biggest difference. You can read all about it HERE.

Be sure to purchase your castor oil, black cumin seed oil and vitamin E oil at Mountain Rose Herbs.  These are the best quality oils and are sure to deliver results since they are pure and unadulterated.  Same goes with Cedarwood, Rosemary and Lavender essential oils.  Mountain Rose Herbs offer a huge selection of organic essential oils at super reasonable prices!!
