Natural Eyelash Growth Serum Recipe

Long eyelashes are a classic feminine trait and many women have gone to great lengths (pun intended) for longer eyelashes. Unfortunately, many treatments like eyelash extensions and growth serums can cause allergic reactions, infection, or other problems.

Never fear, there’s a natural way to encourage lash growth… all you need is a little castor oil!

Get Longer Eyelashes Naturally

Of course, there is a genetic aspect to long eyelashes, but that doesn’t mean that those without the lucky genes can’t increase their eyelash length. I have a cousin who naturally has super-long dark eyelashes that look like extensions.

My eyelashes are decently long but definitely not that dramatic. I have been experimenting with natural ways to increase my eyelash length and thickness.

There does seem to be a connection between nutrition and hair health, so if a person isn’t getting enough fat-soluble vitamins, b-vitamins, vitamin C, and collagen.

Overuse of eye products, especially long-lasting mascaras or fake lashes, can weaken lashes or lead to lash loss.

Natural Eyelash Extensions?

After publishing my homemade mascara, many people asked if there was a natural way to make fiber lash mascara or eyelash extensions. I’m yet to find a natural version of false eyelashes since most glues contain formaldehyde. Most fiber lash products also contain questionable ingredients.

What I did find, however, was a natural way to make lashes look as long as fake lashes using only natural ingredients.

This natural eyelash growth serum uses:

  • Castor oil– Natural source of omega-6 fats, proteins, and vitamins that helps encourage dramatic hair growth
  • Emu oil– “highly anti-inflammatory, moisturizing, anti-wrinkle, penetrating, a transdermal carrier, promotes skin regeneration, non-comedogenic (does not clog pores), nourishing, anti-aging and bacteriastatic.” (source)
  • Coconut oil
  • Vitamin E oil (optional)

Castor oil alone would give noticeable results, as it has been extremely helpful for lengthening and thickening my hair, but the addition of emu oil, coconut oil, and vitamin E give this serum a wider range of fatty acids and nutrients to help speed eyelash growth.

TIP: Christa of The Whole Journey recommends adding 1 drop of lavender essential oil to mascara to speed eyelash growth. I haven’t tried this yet, but it could be added to this serum for additional benefit. (Just always use caution and do your own research when using essential oils!)


Eyelash Growth Serum Recipe

Help speed eyelash growth with the serum made with natural ingredients.


  • Combine all the ingredients in a small dropper bottle and swirl gently to combine.

  • To use, squeeze one drop onto your finger or a cotton swab and gently massage into lash line. I prefer to do this at night to let it work overnight before washing my face in the morning.

  • Use daily for best results.


Store in an airtight container for up to one year.


TIP: Also use on eyebrows to help with thinning eyebrows! This will last up to a year as long as it is kept in an air-tight container. Be careful not to add water, aloe, or other liquid ingredients that will spoil.
