We often ignore these feminine traits, but long eyelashes and fuller eyebrows contribute significantly in defining your face and enhancing your beauty.

A poor diet and excessive use of eye products affect the quality and thickness of your brows and lashes. Shaving or over-plucking your brows also contributes to scanty growth. Plus, your genes play a significant role in deciding their shape and size.

While the market is flooded with mascaras, brow pencils and fillers that make up for the lack of naturally fuller and thicker lashes and brows, regular use of these products can make them brittle and promote breakage. Also, these cosmetics don’t come cheap and put a burden on your pocketbook.

If you are not blessed with gorgeous brows and lashes, there is one inexpensive ingredient that can help you achieve naturally thicker brows and longer lashes – castor oil.

Nourish your hair follicles with castor oil to grow thicker eyebrows and eyelashes

Derived from the seeds of ricinus communis plant, castor oil is rich in ricinoleic acid, a monounsaturated fatty acid that nourishes hair follicles and promotes healthy hair growth. When applied over the eyebrows and eyelashes, it leads to thicker hair growth and can even activate dormant hair follicles.

To use castor oil for thicker eyebrows and eyelashes, you can either apply it directly or mix it with other enriching ingredients to boost hair growth. We bring you the six best ways to get thicker eyebrows and eyelashes with castor oil.

Before applying a castor oil remedy, remove all your makeup and wash your face thoroughly with a cleanser and warm water.

Note: Use 100% organic, cold-pressed and hexane-free castor oil only. Also, if applying castor oil causes any skin irritation, wash it off immediately.

Method 1: Castor Oil

Castor oil is safe to apply directly on your eyelashes and eyebrows to make them fuller and more voluminous over time. The thick castor oil helps cleanse the pores to dislodge any gunk, while the fatty acids in the oil help nourish and strengthen the hair follicles.

Since castor oil is a highly viscous oil, it is preferable to apply it at bedtime and wash it off in the morning.

Single-Step Method: Apply plain castor oil on your brows & lashes daily

  • Leave it on and go off to sleep.
  • In the morning, wash off the oil with face cleanser and warm water.

Repeat this remedy every night for at least 6 weeks to use castor oil for thicker eyebrows and eyelashes.

Method 2: DIY Eyelash & Eyebrow Serum

Ditch those pricey commercial eyelash serums for this easy-to-make lash conditioner using castor oil and aloe vera gel.

While the fatty acids in castor oil help moisturize and strengthen the hair follicles, the aloe vera gel helps form a protective coating on the hair shafts to prevent breakage. Aloe vera further adds a natural shine to your brows and lashes. Both castor oil and aloe vera are also antibacterial and antifungal and will kill any infection stalling hair growth.

  • Always remove your makeup before going off to sleep to prevent infection.
