- Environmental stressors, genetics, hormones and lifestyle habits all impact hair health, making it difficult to maintain thick, long hair.
- The cycle includes anagen (growth), catagen (transition), telogen (resting) and exogen (shedding) and disruptions in this cycle can affect hair thickness and growth.
- DHA, a type of omega-3, supports hair growth at the cellular level by keeping hair follicles in the anagen phase longer.
- Omega-3s have anti-inflammatory properties that promote a healthier scalp, while studies show they can increase hair density, thickness and reduce shedding.
- Consuming omega-3-rich foods or supplements and using topical options like flaxseed gel can work together to improve hydration, shine and overall hair health.
From environmental stressors like pollution and heat styling to internal factors such as hormones and genetics, many variables can influence how your hair grows. That's why achieving or even maintaining long, thick and healthy hair can feel like a constant challenge.
While popular supplements like collagen and biotin often dominate the conversation, another powerful yet underrated nutrient worth considering is omega-3 fatty acids.
Understanding the hair growth cycle
Before diving into how omega-3s support hair health, it's helpful to understand how hair grows. Each strand on your head follows a natural cycle made up of four distinct phases:
1. Anagen (Growth phase):
This is the active growth stage, where hair follicles are producing new hair. It's also the longest phase, lasting anywhere from two to seven years, depending on genetics and overall health.
2. Catagen (Transition phase):
In this short phase, lasting about seven to 10 days, hair growth slows down and the follicle begins to shrink.
3. Telogen (Resting phase):
During this stage, which lasts around three months, hair stops growing and rests while new strands begin forming underneath. Around 10% to 15% of your hair is in this phase at any given time.
4. Exogen (Shedding phase):
This is when old hair sheds naturally to make way for new growth. Losing 50 to 100 strands a day is considered normal during this phase.
Understanding this cycle is key because any disruption, whether from stress, nutrient deficiencies or illness, can affect hair thickness and growth.
How omega-3s support hair growth
Omega-3 fatty acids, particularly DHA (docosahexaenoic acid), play a vital role in overall health, but their benefits for hair are especially compelling.
Research suggests that omega-3s may help stimulate hair growth at the cellular level. Specifically, DHA has been shown to activate pathways that keep hair follicles in the anagen (growth) phase longer. This means your hair has more time to grow before transitioning to shedding.
In addition, omega-3s have anti-inflammatory properties, which can help calm the scalp and create a healthier environment for hair follicles. A well-nourished, balanced scalp is essential for consistent and strong hair growth.
Another study involving women who took supplements containing omega-3s, omega-6s and antioxidants found improvements in hair density and strand thickness. Participants also experienced a reduction in the percentage of hairs in the telogen (resting) phase, indicating less shedding and more active growth.
Internal and external benefits
Omega-3s don't just work from the inside out – they can also benefit your hair when applied topically.
For example, flaxseed gel, which is rich in omega-3 fatty acids, has gained popularity as a natural styling and conditioning product. It helps lock in moisture, reduce frizz and enhance curl definition, making it especially beneficial for wavy and curly hair types.
When used both internally (through diet or supplements) and externally (via oils or gels), omega-3s provide a dual-action approach to healthier, shinier hair.
The bottom line
If you're looking to improve hair growth, thickness and overall hair health, omega-3 fatty acids are a smart addition to your routine. They work at the root, literally, by supporting follicle function, extending the growth phase and nourishing the scalp.
Omega-3 fatty acids, particularly DHA, play a crucial role in this process by stimulating hair growth, reducing inflammation and promoting a healthy scalp environment.
While results won't happen overnight, consistent intake of omega-3s, whether through fatty fish like salmon and mackerel or high-quality supplements, can make a noticeable difference over time. BrightU.AI's Enoch also noted that embracing natural, holistic approaches to hair care, such as using flaxseed gel, can further complement the benefits of omega-3s, providing a comprehensive strategy for achieving the hair you desire.
