Does Fish Oil Help Hair Growth? Recommended Dosage

Fish oil, renowned for its omega-3 essential fatty acids, brings a host of health benefits, particularly for heart and potentially for hair health. As we explore the question, “Does fish oil help hair growth”, this article will examine how these fatty acids might not only enhance overall wellness but also improve hair health and reduce hair loss.

We will discuss how to effectively integrate fish oil into your daily regimen, the recommended dosages, possible side effects, and additional ways to increase your omega-3 intake. Keep reading to learn more about how fish oil could significantly boost your health and contribute to stronger, healthier hair.

Does Fish Oil Help Hair Growth?

Fish oil is well-known for its numerous health benefits, and its potential to enhance hair growth is also gaining attention. Although research is still developing in this area, there are some encouraging signs that fish oil could help boost hair growth by extending the anagen phase, the active growth stage of hair.

For instance, a 2018 study on animals found that fermented mackerel oil prolonged this growth phase, though it’s worth noting that animal results might not always mirror human outcomes. More relevant to humans, a 2015 study with 120 women showed that supplements containing both omega-3 and omega-6 fatty acids decreased the number of hairs in the resting phase and increased those in the growth phase. After six months, participants observed a significant decrease in hair loss and enhanced hair growth compared to those who didn’t take the supplements.

These results are promising, yet more research is necessary to definitively prove the benefits of fish oil for hair growth in a broader range of people.

Note: For those considering fish oil for hair health, integrating it with a balanced diet rich in other nutrients can potentially enhance its benefits, supporting not only your hair but overall health.

Fish Oil’s Hair Benefits

Fish oil and its rich omega-3 content are increasingly popular for their potential benefits in promoting healthier, thicker hair. Here’s a closer look at how fish oil can contribute to hair health:

Improves Hair Thickness

A study from 2015 demonstrated that women who took supplements combining omega-3s, omega-6s, and antioxidants experienced less time in the hair’s resting phase and more in the growth phase.

After six months, they noticed significant improvements in hair thickness and density, indicating better overall hair health.

Promotes Growth

A 2018 study on the topical application of mackerel-derived fermented fish oil extract showed promising results. This treatment seemed to stimulate hair growth and reduce the resting phase of hair cycles.

It was noted that DHA, a key omega-3 fatty acid in fish oil, helped increase the production of cells critical for regulating hair growth. However, since this study was on mice, more research is needed to confirm similar effects in humans.

Reduces Hair Loss

In the aforementioned 2015 study, many women reported a noticeable reduction in hair loss after six months of using the supplement. This suggests that fish oil could be a valuable addition to hair loss prevention strategies, as it not only supports hair growth but also combats factors like nutritional deficiencies and oxidative stress that can lead to hair loss.

Hair loss is a common concern across all genders, influenced by factors like nutritional deficiencies and oxidative stress. Fish oil supplements, rich in omega-3 fatty acids, can provide essential support against these contributors, promoting not only hair growth but also general health.

Additional Uses of Fish Oil

Fish oil, celebrated for its omega-3 fatty acid content, offers a plethora of health benefits beyond hair improvement. Here’s a look at some key additional benefits:

  • Heart Health: Rich in EPA and DHA, fish oil has been proven effective in reducing cardiovascular risks. These omega-3 fatty acids help lower levels of cholesterol and triglycerides, decrease blood pressure, and prevent arterial plaques that can lead to atherosclerosis. Regular consumption of fish oil supports heart health and may significantly reduce the risk of heart diseases.
  • Brain Function: Omega-3 fatty acids are crucial for maintaining brain health. Various studies indicate that fish oil can be beneficial in managing mental health conditions such as depression. It also shows potential in alleviating symptoms of ADHD in children and in slowing down age-related cognitive decline and dementia.
  • Eye Health: A deficiency in omega-3 fatty acids can increase the risk of eye diseases, including age-related macular degeneration (AMD). Consuming fish oil either through diet or supplements has been associated with a lowered risk of AMD, underscoring its importance in maintaining eye health.
  • Reduced Inflammation: The anti-inflammatory properties of fish oil are well-documented, making it an excellent supplement for reducing systemic inflammation. This can prove beneficial for individuals suffering from conditions like inflammatory bowel disease, rheumatoid arthritis, and asthma.

Note: While fish oil offers diverse health benefits, it’s important to consider the right dosage and consult with a healthcare provider to avoid potential interactions with other medications and ensure these benefits are fully realized.

Additional Uses of Fish OilDoes Fish Oil Help Hair Growth

Applying Fish Oil for Hair Growth

Utilizing fish oil for hair growth can be approached through various methods, tailored to individual preferences and tolerances:

  • Diet: Incorporating fatty fish such as salmon, mackerel, and tuna into your diet is a natural way to consume fish oil. These fish are excellent sources of omega-3 fatty acids, which contribute to the overall health of your hair.
  • Topical Application: Directly applying fish oil to your scalp, skin, and hair roots can be an effective method for enhancing hair health. However, it’s important to note that fish oil has a distinctive, often unpleasant odor which might be off-putting for some users.
  • Supplements: If you prefer a more straightforward and odor-free method, fish oil capsules are available. These supplements offer a convenient way to obtain the benefits of fish oil without altering your diet significantly.

Who Should Avoid Fish Oil?

Fish oil is generally beneficial for many, but there are specific groups who should be cautious or avoid it altogether:

  • Allergies: Individuals with allergies to fish or soybeans should avoid fish oil supplements, as they are derived from fish and may contain soy, both of which are common allergens.
  • Diabetes: People with diabetes, particularly type II, need to be cautious with fish oil supplements. High doses can elevate blood glucose levels, potentially complicating diabetes management. Such individuals should only use fish oil under medical supervision.
  • Liver Disease: Those with liver disease should consult their healthcare provider before taking fish oil, as it can influence liver function, potentially exacerbating existing conditions.
  • Pancreas Disorders: Individuals with disorders affecting the pancreas should seek medical advice before incorporating fish oil into their regimen, due to potential adverse effects on pancreatic function.
  • Underactive Thyroid: Fish oil may interact with thyroid function. People with hypothyroidism should consult with a doctor prior to using fish oil supplements to ensure it does not interfere with their thyroid management.
  • Alcohol Consumption: Caution is advised for individuals who consume more than two alcoholic beverages daily, as fish oil can interact with alcohol, influencing its effects and potentially leading to health complications.

Recommended Fish Oil Dosage

Determining the optimal daily intake of EPA and DHA from fish oil can be somewhat ambiguous, as they are not classified as essential nutrients. However, Harvard Health suggests that for adults, a typical dosage should range between 250–500 milligrams (mg) per day of EPA and DHA combined.

The concentration of these omega-3 fatty acids can vary significantly between different brands and formulations. For instance, 1,000 mg of fish oil from one brand might contain different levels of EPA and DHA compared to the same quantity from another brand. This variance makes it crucial to check the supplement label for specific content details.

For those preferring natural sources, oily fish like salmon, mackerel, and sardines are excellent sources of EPA and DHA. For vegetarians or vegans, algae oil provides a plant-based alternative rich in these omega-3s.

To maximize the benefits, taking fish oil supplements with a fat-containing meal is advisable, as some studies indicate that this can enhance the absorption of fatty acids.

Fish Oil’s Efficacy in Treating Thinning Hair

Fish oil is well-known for its health benefits, and it might also help with thinning hair. When hair grows for a longer period, it can look fuller and thicker. This is where fish oil comes in, as it’s packed with omega-3 and omega-6 fatty acids that may promote longer growth phases for hair.

A study in 2015 highlighted these effects, showing that people who took supplements containing these fatty acids noticed their hair got thicker and denser after six months.

Potential Side Effects of Fish Oil Usage

Fish oil is generally well-received by many, with only minor side effects reported. Common issues include:

  • Bad breath
  • Fishy aftertaste
  • Unpleasant-smelling sweat
  • Indigestion
  • Nausea
  • Diarrhea

Furthermore, taking high doses of fish oil can impair proper blood clotting, which is particularly concerning for individuals with bleeding disorders. Such high amounts can also amplify the effects of medications that prevent clotting, like warfarin (Coumadin).

It’s crucial for individuals with pre-existing health conditions to consult a healthcare professional before incorporating fish oil supplements into their regimen.

Note: To mitigate some side effects like bad breath and fishy aftertaste, consider taking supplements with meals or trying enteric-coated capsules, which can also help reduce indigestion.


Research indicates that fish oil, rich in EPA and DHA, has potential benefits for hair growth, leading many to ask, “Does fish oil help hair growth?” These omega-3 fatty acids may help nourish the hair follicles, promoting stronger and healthier hair. While the effectiveness of fish oil for hair loss remains a topic of interest, further studies are needed to conclusively determine its impact.

For those considering this supplement specifically for hair health, it’s essential to choose reputable brands. Consulting with a healthcare professional is advisable, especially for individuals with existing health conditions. This guidance ensures that you can safely explore the benefits of fish oil for hair loss.
