Quick Recipe

Give your lashes a nourishing treat with this homemade blend.

  • Prep time: 10 minutes (plus 2-3 hours infusion time)
  • Best for: Supporting the appearance of longer, thicker, and stronger lashes
  • Use type: Oil serum
  • Main ingredients:
    • Castor Oil
    • Flaxseeds
    • Rosemary Essential Oil

Ingredients

  • 2 tablespoons high-quality Castor Oil (cold-pressed, hexane-free is preferred)
  • 1 teaspoon whole Flaxseeds
  • 1-2 drops Rosemary Essential Oil (ensure it’s therapeutic grade)
  • Small, clean, airtight container (like a mascara tube or a small dropper bottle)
  • Fine mesh strainer or cheesecloth

How to Make It

  1. Gentle Infusion: In a small, heat-safe glass jar or bowl, combine the castor oil and whole flaxseeds. Place this jar into a pot of water (creating a double boiler setup) and gently heat on low for 2-3 hours. Do not let the oil boil. This slow, gentle heat helps extract beneficial compounds from the flaxseeds into the castor oil.
  2. Cool and Strain: Remove from heat and let the mixture cool completely. Once cool, strain the oil through a fine mesh strainer or a piece of cheesecloth into a clean bowl to remove all flaxseed particles. Ensure no solid bits remain, as these could irritate your eyes.
  3. Add Essential Oil: To the strained castor oil, add 1-2 drops of rosemary essential oil. Stir well to ensure the essential oil is evenly distributed.
  4. Store: Carefully pour your finished lash serum into a clean mascara tube with a wand or a small dropper bottle.

How to Use It

  1. Cleanse Lashes: Before application, ensure your lashes are clean and free of makeup.
  2. Dip and Wipe: Dip the clean mascara wand or a cotton swab into the serum. Wipe off any excess oil on the edge of the container to prevent dripping.
  3. Apply Carefully: Gently apply a thin layer of the serum along the base of your upper and lower lash lines, just as you would apply liquid eyeliner. You can also brush it lightly through the length of your lashes.
  4. Avoid Contact: Be very careful to avoid getting the oil directly into your eyes. If it does get into your eyes, rinse immediately with clean water.

How Often to Use It

For best results, apply this DIY lash serum once daily, preferably in the evening after you have removed all your makeup and cleansed your face. Consistency is key with natural remedies.

Why These Ingredients Are Used

Castor Oil

Castor oil is a popular natural remedy for hair growth, including eyelashes and eyebrows. It is rich in ricinoleic acid, a fatty acid believed to help stimulate circulation to hair follicles and nourish them. It also provides deep conditioning, which can help prevent breakage and make lashes appear thicker and shinier.

Flaxseeds

Flaxseeds are packed with omega-3 fatty acids, lignans, and antioxidants. When infused into oil, these compounds can provide nourishment to the lash follicles, potentially supporting stronger, healthier lash growth and reducing brittleness. They are known for their moisturizing and strengthening properties.

Rosemary Essential Oil

Rosemary essential oil is widely recognized for its ability to stimulate hair growth and improve circulation to the scalp and follicles. In highly diluted amounts, it can be beneficial for lashes by supporting the health of the follicles, which in turn may encourage the appearance of fuller and more robust lashes.

What Results to Expect

With consistent use, this natural lash serum may help your lashes feel stronger, more conditioned, and appear longer and thicker over several weeks. Individual results can vary, and patience is key when using natural remedies. You may notice less lash breakage and a healthier-looking sheen.

Safety Notes

  • Patch Test First: Always perform a patch test on a small, inconspicuous area of skin (like behind your ear or on your inner arm) 24 hours before applying the serum to your lashes to check for any allergic reactions or sensitivities.
  • Eye Irritation: The eye area is very delicate. If you experience any redness, itching, burning, or discomfort, discontinue use immediately and rinse your eyes thoroughly with water.
  • Avoid Direct Eye Contact: Be extremely careful to avoid getting the serum directly into your eyes. If contact occurs, flush thoroughly with cool water.
  • Cleanliness is Key: Ensure all tools and containers are thoroughly clean to prevent bacterial contamination, which can lead to eye infections. Replace your serum every 2-3 months or if you notice any changes in smell or appearance.
  • Consult a Professional: If you have any pre-existing eye conditions, sensitivities, or are pregnant or breastfeeding, consult with a doctor or ophthalmologist before using any new eye-area treatments.
  • Rosemary Essential Oil: Essential oils are potent. Use only 1-2 drops for the entire recipe, as excessive amounts can cause irritation.
