Eyelash & brow serums
Castor oil is commonly used as a nightly conditioning oil on eyelashes and eyebrows, applied with a spoolie or fine-tip applicator. Products in this category range from tiny serum tubes with built-in wands to plain castor oil repackaged in lash-friendly bottles. Be skeptical of listings that promise lash growth — castor oil conditions the hairs you have, and growth claims are not supported by evidence.
The table ranks current Amazon listings by price per fluid ounce, which is eye-opening here: lash serums are often a fraction of an ounce, so the per-ounce price can be many times what plain castor oil costs. Sometimes the applicator is worth it; the table lets you decide. Use extra caution near the eyes — apply sparingly to lashes and brows only, stop if you get irritation or blurry vision, and see a doctor if irritation persists.
