Fish Oil For Hair Growth

Welcome to our discussion about fish oil and its potential benefits for hair growth and hair loss prevention. As a commonly consumed dietary supplement rich in omega-3 fatty acids. Fish oil is believed to promote overall health. And experts are using it as proponents of natural medicine to treat a range of symptoms. 

In recent years, some studies have suggested that fish oil may also have a positive effect on hair growth and strength. Although more research is needed to fully support these claims. We’ll explore the potential benefits of fish oil for hair health. And discuss the various ways to incorporate it into your haircare routine. Additionally, we’ll touch upon the safety considerations and potential side effects of taking fish oil supplements.

Experts of natural medicine believe that fish oil, a dietary supplement containing high levels of omega-3 fatty acids and other essential nutrients, can contribute to a person’s overall health. They use fish oil to treat various symptoms, including mental health conditions and chronic diseases. Fish oil is believed to regulate the body’s natural functions. Therefore, it may have additional benefits, such as triggering hair growth, promoting hair strength, and nourishing hair follicles.

Omega-3s Aid In Promoting Hair Growth

Regarding supplementation, there have been only a few studies investigating the effects of omega-3 fatty acids and fish oil on hair growth and nails. In the February 2017 issue of the Journal of Clinical and Aesthetic Dermatology. A small study was conducted on 10 participants with androgenetic alopecia (known as male-pattern baldness) who were each given a twice-daily supplement containing a mix of fish oil, flaxseed oil, antioxidants, and melatonin. 

After six months, eight people (representing 80 percent of participants) experienced an increase in hair growth. A more extensive study was conducted in 2015 in the Journal of Cosmetic Dermatology, which involved 120 participants. The study compared a group taking a supplement containing fish oil and vitamins C and E (among many other ingredients) with a control group. After six months, 62 percent of those in the supplement group that has studied, saw an increase in hair density compared to 28 percent in the control group. However, more research is needed to understand the potential mechanisms involved in this.

Supplements may contain fish oil or omega-3s, and other ingredients, like antioxidants, which may act synergistically. Therefore, it’s important not to assume that taking fish oil or omega-3s alone in a supplement will promote hair growth.

Regarding topical application, a study published in September 2018 in the International Journal of Molecular Sciences found that the application of fermented mackerel oil to rodents’ whiskers helped stimulate follicles. However, according to Kerry Yates, a trichologist and founder of Colour Collective in Dallas, “topical application of fish oil will not support hair growth or scalp health.”

Overall, the most effective approach to promote hair growth is to maintain a healthy diet, use gentle hair-care products, and seek medical treatment if experiencing hair loss, starting with a dermatologist.

What Type Of Fish Oil Is Considered The Most Effective

According to the National Center for Complementary and Integrative Health (NCCIH), you can obtain fish oil through various means, including fish oil supplements, fish liver oil supplements (such as cod liver oil), and shellfish and whole fish. 

In addition to omega-3s, whole fish also contain a variety of other vitamins and minerals not found in supplements. Registered dietitians recommend choosing whole fish over pills to receive the potential benefits of fish oil. 

Can Fish Oil Benefit Your Hair And Nails

The role of fish oil in hair and nail health is not well-established due to a lack of data. Rather than focusing on specific nutrients claiming to promote hair growth. It is crucial to consume a balanced diet that provides the necessary omega-3s for overall body function. According to experts, various vitamins can support deficiencies. But they do not ensure hair growth.

Experts suggest that if you consume a well-balanced diet that provides all the necessary nutrients, including omega-3s, it is unlikely that you have a deficiency. Taking more omega-3s than required through supplements may not necessarily helpful if there is no deficiency.

Can Fish Oil Help With Thinning Hair

Fish oil may aid in thinning hair for the same reasons it can help with hair loss. If a person’s hair spends more time in its growth stage. It may give them the appearance of having more hair. Furthermore, participants’ reports from a 2015 study showed that taking a supplement containing omega-3s and omega-6s led to greater hair diameter and density after six months.

Utilizing Fish Oil for Hair

There exist different ways to utilize fish oil for hair. Depending on one’s preference and tolerance, they can select one of the following methods:

Topical Application: Fish oil can directly apply to the scalp, skin, and hair roots. However, it should notice that it has an unpleasant odor.

Diet: Incorporating fatty fish such as salmon, mackerel, and tuna into one’s diet is a rich source of fish oil.

Supplements: Taking fish oil capsules for hair growth is an easier and more pleasant way to reap the benefits of fish oil.

Fish Oil Benefits

Omega-3 has several benefits for hair. 

  • Firstly, it protects the skin and hair against the damaging effects of ultraviolet rays from the sun by acting as a barrier against free radicals. This protection against the sun also increases resistance to other damages caused by excessive UV exposure. 
  • Secondly, omega-3 has anti-inflammatory properties that can help soothe and hydrate the scalp and treat disorders such as psoriasis, eczema, and dandruff. 
  • Thirdly, it boosts hair growth by improving blood circulation in the scalp, providing nourishment to the follicles, and infusing hair with life. 
  • Fourthly, it reduces hair loss by ensuring the current hair growth is not hampered. 
  • Finally, omega-3 strengthens hair by healing weak follicles and promoting strong and healthy hair growth. The dosage and intensity of omega-3 intake depend on individual body requirements and consultation with a doctor is recommendable.

Because the omega-3 in fish oil provides essential proteins and nutrients to hair follicles and skin, prevents hair follicle inflammation, and promotes circulation in the scalp that may trigger hair growth. 

Although there is currently not enough clinical research to fully support these claims. Some studies have shown positive results. For example, a 2015 study showed that women taking a fish oil supplement experienced significantly increased hair growth and reduced hair loss. 

While a 2018 study indicated that applying mackerel-derived fermented fish oil (FFO) extract topically to mice significantly stimulated hair growth.

 Anecdotal evidence also suggests that topical application of fish oil may add luster and shine to your hair as well as make it healthier. However, if you choose to apply fish oil directly to your scalp, be aware that it may have an unpleasant odor.
