Castor Oil for Hair, Skin, and Nails
Castor oil is a thick, single-ingredient oil that shows up in a lot of hair, skin, and nail routines. It is not a proven hair-growth treatment, and we will not tell you it is one. What it can honestly help with is conditioning dry-looking hair and brows, softening rough patches of skin, and caring for dry nails and cuticles.
Pure Castor Oil
One ingredient: Ricinus Communis (Castor) Seed Oil. Fragrance-free. Made in Canada, $15.99.
How to use it, by area
Hair: warm a few drops between your hands and smooth over lengths and ends, or apply before shampooing.
Brows: apply a very small amount to clean brows, avoiding direct contact with your eyes.
Skin and cuticles: massage a small amount onto dry areas, nails, and cuticles.
Does it actually grow hair or lashes?
There is no solid evidence that castor oil makes hair grow faster or thicker from the follicle; that kind of change usually comes down to genetics or, for hair loss, a medical cause worth discussing with a doctor. What castor oil can genuinely help with is different: it can help condition dry-looking hair and brows, which can make ends look and feel less rough and reduce the look of breakage. If your goal is fuller, healthier-looking hair over time rather than faster growth, that is a fair way to think about it.
Why one ingredient
Our castor oil is exactly one ingredient: Ricinus Communis (Castor) Seed Oil. No fragrance, no filler oils. That makes it easy to layer under or over other products without adding a scent or extra ingredients you did not ask for.
Common questions
Will this grow my eyelashes or eyebrows?
We cannot promise growth. It can help condition brows and lashes so they look and feel less dry and brittle. Apply a very small amount and avoid direct contact with your eyes.
Can I use it on my hair, skin, and nails all with one bottle?
Yes, that is the point of a single, simple oil. Use a small amount wherever you need it.
Is it fragrance-free?
Yes. It is a single-ingredient, fragrance-free oil.
How often can I use it?
Most people use it a few times a week, though daily use on nails and cuticles is fine for most skin.
External use only. Patch test before first use. Stop use if irritation occurs. Avoid direct contact with eyes.
