Flax seeds, derived from the flax plant (Linum usitatissimum), have been used for centuries for various health purposes. These seeds are now recognized for their potential benefits in supporting hair and scalp health. They contain specific components that contribute significantly to hair wellness.
The Nutritional Components that Benefit Hair
Flax seeds contain several compounds that benefit hair health. One primary component is Alpha-Linolenic Acid (ALA), a plant-based omega-3 fatty acid. This fat is metabolized in the body and plays a role in cellular functions related to the hair follicle environment.
The seeds are also rich in lignans, which are natural plant compounds functioning as antioxidants and phytoestrogens. Lignans are present in flax seeds at high levels, offering protection against cellular damage. Flax seeds are also a good source of Vitamin E, an antioxidant that helps protect the integrity of the hair and scalp.
Another important constituent is mucilage, a water-soluble fiber found in the seed coat. When flax seeds are soaked or boiled, this mucilage is released, creating a slippery, gel-like substance. This substance provides moisturizing and conditioning properties when applied topically to the hair shaft.
Mechanisms of Action: How Flax Seeds Improve Hair and Scalp Health
The Alpha-Linolenic Acid (ALA) works primarily through its anti-inflammatory properties. Reducing inflammation on the scalp promotes a calmer environment for hair follicles, which is conducive to healthy growth.
Lignans and Vitamin E contribute to hair and scalp health by combating oxidative stress. These compounds neutralize free radicals, which are generated by environmental factors and contribute to the degradation of hair follicles. As powerful antioxidants, they help maintain a healthy scalp environment that supports hair retention and strength.
Topical application, often using flaxseed gel, utilizes the properties of mucilage. This substance acts as a natural humectant, drawing in and locking moisture into the hair strand. This effect smooths the hair cuticle, reducing frizz and dryness, and leading to improved texture and shine.
Practical Application: Using Flax Seeds for Hair Care
Flax seeds can be incorporated into a hair care routine through dietary consumption and topical application. For internal benefits, consuming ground flax seeds is preferred over whole seeds, as grinding maximizes the bioavailability of ALA and lignans. A typical daily intake is one to two tablespoons of ground flax seeds, which can be mixed into smoothies, yogurt, or baked goods.
This internal approach strengthens the hair shaft, reduces breakage, and helps maintain a balanced scalp environment by delivering essential fatty acids and antioxidants. Flaxseed oil is another option, offering a concentrated source of omega-3 fatty acids for internal use.
For topical use, the most popular method is preparing a flaxseed gel, which utilizes the mucilage for conditioning and styling. The gel is made by boiling about one-quarter cup of whole flax seeds in two cups of water until the liquid thickens. The mixture must be strained quickly to separate the gel from the seeds before it cools and becomes too thick.
This homemade gel can be applied to wet hair as a natural styling product to define curls, reduce frizz, and add shine. Flaxseed oil can also be massaged onto the scalp as a pre-shampoo treatment or incorporated into a hair mask. Topical application offers immediate cosmetic effects like improved manageability and reduced dryness.
