Did you know that you don’t have to be genetically blessed to have gorgeous lashes? Sure, you can pay a doctor’s visit, get a prescription, and spend over $100 on an eyelash growth serum that’s full of unnatural ingredients that lead to possible scary side effects. You could also get false lashes that will eventually weaken your real lashes while breaking the bank. Personally, I’m not interested in any of these options.

There’s a much safer, more affordable, and easier way to enhance your own lashes using natural ingredients that have been shown to be effective in conditioning and stimulating hair growth, without the adverse side effects.

First, let’s discuss the cause of thinning lashes… Of course, some people are just born with shorter, thinner lashes than others, but there can be health issues that cause lashes to thin and fall out. These issues should be confirmed to properly fix the issue.


Possible health reasons for thinning eyelashes:

  • Age is the number one cause of thinning/falling eyelashes and not a medical issue. In fact – if you don’t age – you’re dead, so aging is a good thing! However, supporting lash health can give you thicker lashes.
  • A hormonal imbalance of thyroid hormone can lead to hair loss on the head, eyebrows and eyelashes.
  • Chemotherapy can lead to hair loss.
  • Not removing your makeup before bed can significantly contribute to eyelash loss and thinning eyelashes.
  • Remove mascara in a non-gentle way.
  • Allergies can cause your eyes to become itchy, and itching can lead to eyelash loss.
  • Prolonged use of false eyelashes. Eyelash extensions can put stress on your natural lashes, causing them to weaken and fall out.
  • reaction to certain medications.

Why are traditional eyelash growth serums not ideal?

The FDA has approved many eyelash serums, but they warn of possible side effects these serums could cause. Eyelash growth serums can cause side effects such as allergic reactions, eye irritation with itchy, red eyes, decreased intraocular pressure, darkening of the eyelid skin and, in rare cases, a permanent change in eye color.

What are the risks of eyelash extensions?

According to the American Academy of Ophthalmology, eyelash extensions can cause swelling, temporary or permanent loss of eyelashes, eyelid skin irritation, and eyelid or corneal infection.

Also, the glue used contains several questionable ingredients such as latex, cellulose rubber, cyanoacrylates, benzoic acid, and formaldehyde. The ingredients in eyelash extension removers include formaldehyde, propylene glycol and geraniol.

Eyelash extensions are not only time-consuming, but also expensive.

What oils help your eyelashes grow?

In all my research I have found several scientifically proven natural oils that help hair grow longer and thicker. Healthy hair growth starts with increased blood flow and detoxified hair follicles. Grooming the hair can also give the appearance of thicker, longer lashes.


Castor oil is one of the most common and widely used oils for eyelashes and eyebrows. I use it in this serum because it’s gentle on the eyes and doesn’t cause irritation.

Castor oil is the main active ingredient in this serum. It can be extremely beneficial when it comes to hair growth. castor oil is full of omega-6 fatty acids, vitamin E and proteins. It is easily absorbed into the hair shaft and locks in nutrients. The use of castor oil for hair growth dates back to the ancient Egyptians!

You can even massage castor oil into your scalp before bed to encourage more hair growth on your head! Castor oil also has a pulling effect which I believe the pulling detoxifies the hair follicles and allows the hair to grow. Castor oil is easy to find and can often be found at any health food store.


According to Healthline, there’s evidence that ricinoleic acid, a chemical compound that makes up nearly 90 percent of castor oil, may help reverse hair loss. One study found that the protein prostaglandin D2 (PGD2) is present at high levels in men with male pattern baldness and is one of the factors that stopped the study subjects from regrowing their hair. Another study found that ricinoleic acid may help inhibit PGD2 and possibly help scalp hair grow back.

There are other oils that I recommend for use for hair loss, but since we are dealing with the delicate nature of the eye, castor oil is the only oil I use. If you are interested in a hair growth serum for your brows that contains more hair growth boosting oils check out my DIY brow serum recipe.

Sweet Almond Oil is incredibly gentle and nourishing.

Vitamin E is moisturizing and also helps to strengthen hair. Both vitamin E and aloe vera gel help lengthen lashes, but adding aloe to this recipe doesn’t work well since aloe vera is water-based and doesn’t mix well with oil.

What you need to make DIY eyelash serum:


  • castor oil
  • Sweet Almond Oil
  • vitamin E oil*


  • mascara tubes
  • Small funnel


    1. Fill and empty the mascara tube 3/4 full with castor oil
    2. Fill 1/8 of your mascara tube with sweet almond oil
    3. Fill 1/8 of your mascara tube with vitamin E oil*
    4. Put the lid back on and shake.


*I do not recommend using vitamin E capsules in this recipe.

How to use a DIY eyelash serum:

  • The first thing to do is to thoroughly remove all your eye makeup and remove any cleansers/cleansing oils from your eyes. I like to run cotton swabs over my eye area with micellar water to remove excess oil from my oil cleanser.
  • Use your DIY eyelash growth serum in the evening right before bed.
  • Apply a small amount to the lash line and over the lashes themselves. Make sure you get the oil at the base of your lashes. This is important.
  • Wash your face in the morning as usual.

What about essential oils?

Many essential oils are fantastic for stimulating hair growth. Rosemary, cedarwood, and lavender essential oils are excellent tools when it comes to hair regrowth and thickening. However, I have not managed to conveniently add them to my DIY eyelash serum. Even 1 drop per tube of mascara is too much for my sensitive eyes.

Many other DIY eyelash serums contain a small amount of essential oils, but I don’t recommend using them on your lashes as there’s no way you can get them in your eye.

I add a drop of lavender to my mascara when I first open it. I like to do this for added conditioning as well as bacteria control. There is also a risk that your eyelashes contain mites. Here, too, lavender can provide a quick and easy remedy.

Add lavender at your own risk. I’ve never had it mess up my mascara, but one reader was quite upset with me because she felt it ruined her brand new mascara tube.

How quickly can results be seen after using a DIY eyelash serum overnight?

The result of this serum varies from person to person. Some people see results immediately. I read from a woman that she had to stop using the serum because her bottom lashes were getting too long!

I’ve been using this eyelash growth serum for a few weeks and I can already see a difference.

Remember, a small amount goes a long way — you don’t want the oil running down your face all night, so apply a minimal amount to your mascara wand before applying. You can still see without too much blurring after applying it, it’s actually very comfortable.

Precautions for using an eyelash serum:

You may want to patch test before using. Because we use no essential oils and only gentle carrier oils, eye sensitivity to this recipe is very uncommon. However, if you’re concerned, I recommend rubbing a few drops onto your inner arm and watching for signs of a reaction for 24 hours.

Embrace and enhance your natural lashes by addressing the root cause of hair loss and using simple ingredients to nourish and detoxify your skin, hair and follicles. Most of the time, fuller lashes can be achieved by using natural oils that don’t compromise healthy lashes.

You have nothing to lose by making this DIY eyelash growth serum. Castor oil for hair growth is an incredibly effective yet natural way to thicken hair.
