Most are willing to try just about anything to achieve luscious, healthy hair. While hair treatments and products can certainly play a role, nutrition is often the only puzzle piece. By recognising the nutritional benefits of mackerel, we can highlight a crucial aspect of holistic hair care: the importance of a balanced diet.

This emphasis underscores that internal nutrition is just as vital as external treatments in the pursuit of beautiful, healthy hair. This article explores the ways mackerel can support hair growth with evidence backed by scientific reasoning.

The nutritional powerhouse: why mackerel?

Mackerel is a fatty fish rich in essential nutrients crucial for hair health. These include omega-3 fatty acids, proteins, vitamins, and minerals. Let's explore these components to better understand mackerel's benefits for hair growth.

1. Omega-3 fatty acids: the hair growth catalyst

One of the standout nutrients in mackerel is omega-3 fatty acids. These essential fats are widely known for their anti-inflammatory properties, which can significantly benefit the scalp by promoting blood circulation.¹ A healthy scalp is a foundation for hair growth and hair strength. Inflammation can inhibit hair follicles, leading to hair thinning and loss.

Omega-3s help reduce inflammation and create a more conducive environment for hair growth. The Journal of Cosmetic Dermatology published a study highlighting that omega-3 supplements can help increase hair density and reduce hair loss.²

2. Protein: the building block of hair

Hair is primarily composed of keratin, a protein. Thus, adequate protein intake is vital for synthesising new hair cells. Mackerel is a rich source of high-quality protein, which provides the necessary amino acids for keratin production. This not only aids in the growth of new hair but also strengthens existing strands, reducing breakage.

Lack of protein in the diet can lead to hair thinning and hair loss, known as ‘telogen effluvium’ (excessive hair shedding after metabolic stress, hormonal changes or medication). Incorporating mackerel into your diet can help prevent this condition, ensuring your hair remains thick and healthy. 

3. Vitamin D: the sunshine vitamin for hair follicles

Mackerel is also an excellent source of vitamin D, a nutrient many people lack, especially during the colder months when sun exposure is limited. Vitamin D plays a crucial role in the creation of new hair follicles, tiny pores from which new hairs can grow. A deficiency in vitamin D has been linked to alopecia, an autoimmune condition that results in hair loss.

Including mackerel in your diet can help boost your vitamin D levels, potentially stimulating new hair growth and preventing further hair loss.

4. Selenium: the scalp protector

Selenium is another vital nutrient found in mackerel. It acts as a powerful antioxidant, helping to combat oxidative stress, which can damage hair follicles and lead to hair thinning. This nutrient also plays a role in the proper functioning of the thyroid gland, which regulates metabolism, including the rate at which hair grows.

A healthy scalp is less prone to infections, which can sometimes cause significant hair loss. Mackerel contains selenium, a mineral with potent antioxidant properties that help protect the scalp from oxidative stress and microbial infections.

Selenium’s antifungal properties are particularly beneficial in combating scalp conditions like seborrheic dermatitis (a condition caused by stress and hormonal changes) and fungal infections, which can disrupt the normal hair growth cycle.

5. B-Vitamins: the stress busters

Mackerel contains B vitamins, including B12, B6, niacin (B3), and riboflavin (B2). These vitamins are crucial for overall hair health. For instance, vitamin B12 is essential for producing red blood cells, which carry oxygen and nutrients to the scalp and hair follicles. Without adequate B12, hair can become weak, brittle, and more prone to falling out.

Vitamin B6 regulates hormone levels. Hormonal imbalances experienced during menopause or certain medical conditions can lead to hair loss.³ Thus, vitamin B6 aids the body in producing melanin, which gives hair its colour and protects it from greying. Additionally, it supports the synthesis of proteins and the metabolism of amino acids, which are essential for healthy hair growth.

Niacin improves blood circulation to the scalp, enhancing the delivery of essential nutrients to hair follicles. Riboflavin, on the other hand, aids in cellular function and energy production, both of which are crucial for the growth and maintenance of hair.⁴

6. Zinc: mackerel benefits for hair growth

Zinc is an essential mineral in mackerel that plays a crucial role in hair tissue growth and repair. It helps maintain the oil glands around the hair follicles, keeping them functioning properly. A zinc deficiency can lead to hair loss, as the hair follicles weaken and become more prone to shedding. By incorporating mackerel into your diet, you can help ensure that your zinc levels are adequate, supporting the repair and regeneration of hair tissues and preventing hair thinning.

FAQ’s

Can I take omega-3 supplements instead of eating fish?

High-quality omega-3 supplements can provide similar benefits to eating fatty fish like mackerel. However, there are a few things to keep in mind:

1. Source and quality: Ensure that the omega-3 supplements you choose are high-quality, ideally sourced from fish oil, krill oil, or algae oil. Look for products that are purified to remove contaminants and have a high concentration of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), the most beneficial types of omega-3s for health
2. Absorption: While supplements can be an effective alternative, the body may absorb nutrients more efficiently from whole foods. Eating fish provides not only omega-3s but also other beneficial nutrients such as high-quality protein, selenium, vitamin D, and B vitamins, which also contribute to hair health

However, it is always advisable to consult with a healthcare professional before starting any new supplement regimen, particularly to determine the appropriate dosage and to ensure no potential interactions with other medications or health conditions. It is also important to note that supplements are not recommended to replace whole foods.

How often should I eat mackerel to see hair growth?

Consuming fatty fish like mackerel about two to three times per week is recommended to see benefits in hair growth. This frequency can provide a consistent supply of essential nutrients such as omega-3 fatty acids, protein, vitamins, and minerals beneficial for hair health. The key is consistency and ensuring that your overall diet is well-rounded, providing all the nutrients your body needs. 

Remember, while diet is a significant factor in hair health, other factors such as genetics, overall health, and hair care practices also play important roles. Proper hair care practices are equally crucial alongside mackerel benefits for hair growth. This includes using gentle, sulphate-free shampoos, avoiding excessive heat styling and being cautious with chemical treatments that can damage the hair shaft.

Regular scalp massages can enhance blood circulation, potentially promoting healthier hair growth. Protecting your hair from environmental factors like UV rays, pollution, and harsh weather conditions by wearing hats or using protective sprays can prevent damage.

Summary

Incorporating mackerel into your diet offers a multitude of benefits for hair growth. From omega-3 fatty acids and high-quality proteins to vital vitamins and minerals, mackerel provides the essential nutrients your hair needs to thrive. Not only does it promote new hair growth, but it also strengthens and protects existing strands. 

Remember, while diet plays a crucial role in hair health, it's essential to approach hair care holistically. This means also considering stress management, adequate sleep, and proper hair care practices. With mackerel as a regular part of your diet, you're on your way to achieving the luscious locks you've always desired.
