What is Linoleic Acid?
Linoleic acid (LA), also known as omega-6 fatty acid, is an essential fatty acid. This means our bodies can't produce it, so we must obtain it through our diet. It plays a crucial role in various bodily functions, but its benefits for hair and skin are particularly noteworthy. Unlike saturated and trans fats, linoleic acid is an unsaturated fat, meaning its chemical structure allows it to remain liquid at room temperature. This unique structure contributes to its many health advantages.Linoleic acid is just one of several beneficial acids for skin health—you can learn more about other skin-loving acids in our guide to what acids are good for our skin
Linoleic Acid's Role in Skin Health
Linoleic acid is a major component of the skin's lipid barrier, the outermost layer that protects against environmental stressors like pollution, sun damage, and dehydration. A deficiency in linoleic acid can lead to:
- Dry, flaky skin: Linoleic acid helps retain moisture, preventing dryness and flaking.
- Increased skin inflammation: LA helps regulate inflammation, reducing redness and irritation.
- Eczema and other skin conditions: Studies suggest that linoleic acid supplementation can improve symptoms of eczema and other inflammatory skin conditions.
- Accelerated aging: By supporting the skin barrier, LA helps protect against premature aging, reducing wrinkles and fine lines.
- Impaired wound healing: Linoleic acid plays a role in the process of skin repair and wound healing.

By maintaining adequate levels of linoleic acid, you can support a healthy skin barrier, leading to softer, smoother, and more resilient skin. Think of it as nature's moisturizer, but far more powerful and effective.
Linoleic Acid's Benefits for Hair Health
Linoleic acid also contributes significantly to healthy hair. Its benefits include:
- Hydrated scalp: Just like it does for skin, linoleic acid helps keep the scalp hydrated, reducing dryness and itchiness.
- Stronger hair follicles: A healthy scalp leads to stronger and healthier hair follicles, which promotes hair growth and reduces hair breakage.
- Shiny, lustrous hair: Adequate linoleic acid contributes to hair's natural shine and luster.
- Reduced hair loss: While more research is needed, some studies suggest a link between linoleic acid deficiency and hair loss.
- Many natural oils rich in linoleic acid offer these benefits. For example, argan oil and grapeseed oil are excellent sources that can be applied topically to hair and scalp.
For individuals experiencing dry, brittle hair or scalp issues, increasing linoleic acid intake could be a beneficial step towards improving hair health and promoting growth.
Dietary Sources of Linoleic Acid
Getting enough linoleic acid is relatively easy through a balanced diet. Good sources include:
- Vegetable oils: Safflower, sunflower, corn, and soybean oils are rich in linoleic acid.
- Nuts and seeds: Almonds, walnuts, flax seeds, and chia seeds are excellent sources.
- Grains: Whole grains like oats and barley contain smaller amounts of linoleic acid.
- Poultry: Chicken and turkey contain some linoleic acid.
- Beyond dietary sources, you can also nourish your skin and hair with topical applications. Explore our fragrance body oils formulated with nourishing ingredients to support your skin's natural barrier."
Important Considerations
While linoleic acid offers numerous benefits, it's important to consume it in moderation as part of a balanced diet. Excessive intake of omega-6 fatty acids, relative to omega-3 fatty acids. Another fatty acid worth exploring is oleic acid, which works synergistically with linoleic acid for optimal skin and hair health. can potentially contribute to inflammation in some individuals. Always consult with a healthcare professional or registered dietitian before making significant dietary changes, particularly if you have any underlying health conditions.
