Castor Oil Benefits for Skin & Hair: 5 Ways to Use It

If you only keep one oil on your bathroom shelf, make it castor oil. Cold-pressed from the seeds of the Ricinus communis plant, this thick, golden oil has been a skincare staple for centuries — and modern skincare keeps rediscovering why. Here are the five benefits that matter most, plus exactly how to use it (including three DIY recipes).

Why "cold-pressed" and "hexane-free" matter

Cheaper castor oils are extracted with heat or chemical solvents like hexane, which can degrade the oil's nutrients and leave residues behind. Cold-pressing squeezes the oil out mechanically, keeping its fatty acids, vitamin E and antioxidants intact. For anything going on your skin, choose organic, cold-pressed, hexane-free — it's the difference between a therapeutic oil and a commodity one.

The star of the show is ricinoleic acid — around 85–90% of castor oil's fatty acid content — supported by omega-6 and omega-9 fatty acids and vitamin E.

Benefit 1: Deep, lasting hydration

Castor oil is a natural humectant — it attracts moisture and seals it into the skin. Its rich fatty acids sink into the deeper layers rather than sitting on the surface, making it one of the best natural answers to dry, flaky, thirsty skin. A few drops pressed into damp skin after a shower does more than many creams.

Benefit 2: Calms inflammation

Ricinoleic acid has well-documented anti-inflammatory properties. In practice, that means castor oil can help settle redness, puffiness and irritation — useful for reactive skin, and the reason it also stars in castor oil packs for tired joints.

Benefit 3: Naturally antibacterial

The same ricinoleic acid is antimicrobial, helping keep breakout-causing bacteria in check while you moisturise — a rare combination, since most antibacterial products dry the skin out.

Benefit 4: Supports skin elasticity

Castor oil supports the skin's own collagen and elastin — the fibres that keep skin firm and springy. Massaged into the face in upward circular motions, it's a favourite natural approach to maintaining firmness and softening the look of fine lines. (More on this in our guide to naturally tightening facial skin.)

Benefit 5: A natural ally against blemishes

Between the antibacterial action, the inflammation-calming and the pore-friendly moisture, castor oil makes a surprisingly good spot treatment. Dab a small amount on the blemish, leave for 15 minutes or overnight, and rinse. Many fans also brush a tiny amount through brows and lashes with a clean spoolie before bed. Always patch test first (see safety below).

How to use castor oil in your routine

• Moisturiser: 2–3 drops pressed into damp skin, morning or night. Its thickness means a little goes a long way — or blend it 1:1 with a lighter oil like jojoba or sweet almond.
• Anti-ageing massage: warm a few drops between your fingers and massage the face in upward circles before bed.
• Spot treatment: dab directly onto blemishes with a clean cotton bud.
• Hair & scalp: massage into the scalp and lengths as a pre-wash treatment for shine and strength.
• Castor oil packs: for joints and tummy comfort — see our full step-by-step castor oil pack guide.

Three DIY recipes

Hydrating face mask: 1 tablespoon castor oil + 1 tablespoon honey + 1 small mashed banana. Apply to clean skin for 15 minutes, rinse with warm water.

Firming night serum: 2 tablespoons castor oil + 1 teaspoon rosehip oil + 3 drops frankincense essential oil. Apply in upward strokes before bed.

Gentle exfoliating scrub: 2 tablespoons castor oil + 1 tablespoon brown sugar + 1 teaspoon lemon juice. Massage gently, rinse well. Best used in the evening, as lemon can make skin sun-sensitive.

How castor oil compares with other carrier oils

• Castor oil: the richest and thickest — deepest hydration, protective barrier, anti-inflammatory. Best for dry skin, targeted treatments and packs.
• Coconut oil: lighter, absorbs fast, great all-rounder — but can clog pores on acne-prone faces.
• Jojoba oil: closest to the skin's own sebum; balanced and non-comedogenic — ideal for oily or blemish-prone skin.
• Sweet almond oil: gentle, vitamin-E rich, good for sensitive skin.

They also work beautifully together — castor oil blends well with any of them.

Side effects and safety

• Patch test first: rub a few drops into your inner arm and wait 24 hours. Skin irritation is uncommon but possible.
• Don't drink it: this guide is about skin use only — ingested castor oil is a powerful laxative and can cause cramping.
• Pregnant or breastfeeding? Check with your doctor before using castor oil products.

Frequently asked questions

What's the difference between cold-pressed and regular castor oil?
Cold-pressed oil is extracted without heat or solvents, preserving far more of its nutrients. Regular (solvent-extracted) oil is cheaper but less potent — and may carry hexane residues.

Is castor oil safe for all skin types?
Generally yes — it's even reasonably pore-friendly. Sensitive skins should patch test first, and very acne-prone skins may prefer it blended with jojoba.

How often can I apply it?
Daily is fine for most people, morning or night.

Can I use it with my other skincare products?
Yes — apply it as the last (or only) step over damp skin. It plays well with everything from cleansers to serums.
