Ingredient review
Broccoli Seed Oil
INCI: Brassica Oleracea Italica Seed Oil
Broccoli seed oil is a lightweight, non-greasy plant oil that mimics silicones, making hair soft and shiny while moisturizing skin without clogging pores.
In plain English
Broccoli seed oil is pressed from the seeds of broccoli plants. It feels very light and silky on skin and hair, similar to the popular silicone dimethicone, but it's a natural oil. It absorbs quickly without leaving a greasy film, so it's great for people who want moisture without heaviness. On hair, it smooths frizz and adds shine without weighing strands down.

Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Broccoli Seed Oil.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A cold-pressed vegetable oil extracted from the seeds of broccoli (Brassica oleracea italica). It is rich in erucic acid (a long-chain fatty acid) and also contains vitamins A, C, and K, plus antioxidants like sulforaphane (though in small amounts).
How it works
When applied to skin or hair, the oil's fatty acids (especially erucic acid) form a thin, flexible film that seals in moisture and smooths the cuticle. This film feels silky, not sticky, and helps reduce water loss from the skin's surface (transepidermal water loss, or TEWL). On hair, it coats each strand, reducing friction and frizz while adding a natural-looking shine.
Pros
Lightweight, non-greasy moisture
Unlike heavier oils (e.g., coconut or olive), broccoli seed oil absorbs quickly and leaves no sticky residue, making it ideal for daytime use and for those with oily skin.
Natural silicone alternative for hair
It gives hair a smooth, shiny finish similar to silicones but is plant-based and biodegradable, appealing to those avoiding synthetic ingredients.
Cons and cautions
Potential allergen for some
People with allergies to broccoli or related cruciferous vegetables may experience skin irritation or contact dermatitis, though this is uncommon.
Less researched than other oils
While anecdotal evidence is positive, there are fewer peer-reviewed studies on broccoli seed oil compared to oils like jojoba or argan, so its long-term benefits are less documented.
Best for
- People with oily or combination skin who want moisture without heaviness
- Anyone looking for a natural alternative to silicones in hair products
Use caution if
- Individuals with a known allergy to broccoli, cabbage, or other Brassicaceae family plants
Usage tips
Safety summary
Broccoli seed oil is generally safe for most people. The main risk is a rare allergic reaction in those sensitive to Brassicaceae plants. It is non-irritating and non-comedogenic for the vast majority of users.
Research notes
Research on broccoli seed oil is limited but growing. Studies confirm its high erucic acid content and its ability to form a protective film on skin. A 2017 study in the Journal of Cosmetic Science found it improved hair smoothness and shine comparable to silicones. More research is needed on its long-term skin benefits.
