Let’s dive deeper into the benefits of Omega-3 fatty acids for hair and how they can transform your hair health from within. Read More

What Is Omega-3 And Why Does Hair Need It?

The body does not produce Omega-3 fatty acids naturally. It is a polyunsaturated or good fat that we need for a healthy heart, nervous system, and metabolic activity [1]. Moreover, their antioxidant properties make them an excellent source of nourishment for hair follicles. They play an important role in improving hair density and preventing hair loss by reducing inflammation, improving circulation, and supplying essential proteins to the scalp.

Is Omega 3 Good For Hair?

Yes, Omega-3 fatty acids are excellent for hair as they strengthen it and prevent the scalp from drying out and becoming flaky. Research also shows that regular intake of Omega-3 supplements can help control early signs of female pattern hair loss by improving hair density [2].

Top Hair Benefits Of Omega-3 For Hair

From boosting hair growth to shielding against stress, here are the top benefits of Omega-3 fatty acids for hair:

  1. Promotes Hair Growth: Omega-3 fatty acids can prolong the anagen or growth phase of the hair cycle by nourishing hair follicles, reducing inflammation, and improving scalp circulation. This helps you achieve longer, thicker hair over time.
  2. Reduces Hair Loss: Omega-3 fatty acids contribute to a healthy scalp environment by improving scalp hydration and boosting blood circulation. This gradually reduces hair loss and thinning.
  3. Strengthens Hair Strands: Taking Omega-3 fatty acids for hair can strengthen hair strands as it supplies essential proteins to the scalp.
  4. Soothes Scalp Inflammation: Omega-3 for hair can help soothe scalp irritation by suppressing inflammation and calming the scalp. They help reduce follicular inflammation and enable them to function optimally.
  5. Prevents Premature Greying: Inflammation and free radicals can lead to premature greying of hair. Due to their antioxidant and anti-inflammatory properties, Omega-3 fatty acids protect the hair follicles against oxidative stress caused by free radicals. This slows down the loss of pigment cells, thereby preventing premature greying.
  6. Protects Against Damage: Omega-3 in your diet can reduce the occurrence of dry scalp, dandruff, and brittle hair. It nourishes the scalp and promotes healthy and more resilient hair growth.
  7. Moisturises And Enhances Shine: Fatty acids are essential for healthy oil secretion. This keeps the scalp moisturised and protects the skin barrier, making hair healthier, stronger, and shinier.
  8. Balances Hormones For Hair Growth: Another benefit of Omega-3 for hair is the regulation of key hormones such as estrogen and testosterone that affect the hair growth cycle. By stabilising endocrine activity, omega-3 helps address hair loss caused by hormonal imbalances in cases such as PCOS, menopause or pregnancy-related hair fall.
  9. Reduces Stress-Related Hair Fall: Omega-3 fatty acids help reduce the cortisol levels triggered by excessive stress, which extends the resting or telogen phase of the hair growth cycle. They also help manage anxiety reducing the risk of stress-induced alopecia.

Best Omega-3 Rich Foods for Hair Health

We now know that Omega-3 fatty acids offer several benefits for hair. It is essential to include them in your diet as the body doesn’t produce them naturally. Here is a list of foods that can provide a rich supply of Omega-3 fatty acids for hair For healthy hair, aim to include a fatty fish such as salmon in your diet twice a week. You can also eat a tablespoon of ground chia seeds or flaxseeds daily to get Omega-3 benefits for hair.

  • Salmon
  • Mackerel
  • Sardines
  • Herring

  • Flaxseeds
  • Chia Seeds

Omega-3 Supplements: Do You Need Them?

Most people can get the required amount of omega-3 from their diets. However, omega-3 supplements can be helpful for individuals who do not consume seafood or follow a vegan/vegetarian diet. They can be taken in the form of algal or fish liver oil. We recommend that you visit a medical professional before including it in your diet plan.

Scientific Studies That Support Omega-3 For Hair

In the recent past, there have been a few studies that support the benefits of Omega-3 fatty acids for hair. A 2015 study established that six months of regular omega-3 and antioxidant consumption resulted in improved hair density and reduced hair loss in women suffering from female pattern hair loss [3]. Another study conducted in 2018 found that including Omega-3 fish oil in the diet can prolong the anagen (growth) phase of the hair cycle in mice [4]. This means Omega-3 can control hair thinning and promotes healthy hair growth.

Can Omega-3 Alone Fix Hair Fall?

Though there are plenty of benefits of Omega-3 fatty acids for hair, it cannot be a one-stop solution for hair fall and other concerns. It is essential to pay attention to your overall health and consult a dermatologist for a holistic approach.
