Can fish oils prevent or reduce hair loss?

Research shows that the fatty acids in fish oil may help improve scalp health which may reduce hair loss.

Fish oil is a natural source of the omega 3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

Numerous studies have shown that these fatty acids play a major role in skin health and may help improve hair growth.

Researchers believe hair loss is caused by:

  • hormones
  • medicines
  • infections
  • disease
  • diet

Other causes of hair loss are androgenic alopecia, inflammation of the scalp and lacking certain nutrients in your diet.

This article with look at the possible health benefits of fish oil for reducing hair loss and improving scalp health.


Fish Oil May Reduce Hormone That Causes Hair Loss

Doctors believe that one of the most common hair loss conditions is called androgenic alopecia.

In men, this condition is typically called male pattern baldness. It usually begins with hair loss above the temples and may slowly lead to partial or complete baldness.

In women, androgenic alopecia shows at a more generalized thinning of the hair all over the scalp with minimal change in the hairline.

Androgenic alopecia is primarily caused by a hormone called dihydrotestosterone.

A study published in the July 1992 issue of The Biochemical Journal showed that a DHA (found in fish oil) inhibits the production of dihydrotestosterone.  


Fish Oils May Improve Scalp Health

Another possible factor involved in hair loss is inflammation of the hair follicle.

Studies show that fish oils have an anti-inflammatory effect and enhance wound healing.

Additional research shows these oils can help dry skin and eczema by reducing the production of inflammatory co-factors in the skin.

All of these properties could help improve overall scalp health and promote hair growth.


Adding Fish Oil to Diet May Stop Hair Loss

Having a deficiency of certain vital nutrients in your diet may also increase your risk for hair loss.

Research published in the Jan. 2013 issue of Dermatologic Clinics concluded that a deficiency of essential fatty acids can lead to hair loss, as well as hair color changes.

Another study in The Archives of Dermatology looked at a 19 year old man who had a dietary deficiency of omega 3 fatty acids and suffered from hair loss. Researchers applied a topical solution of essential fatty acids to the scalp and it reversed his alopecia, scalp dermatitis and de-pigmenation of the hair.



The above research highlights the possible benefits of fish oils for reducing hair loss and improving scalp health.

Studies indicate that fatty acids in fish oil may help reduce the hormone and inflammation that causes hair loss in some people.

Due to the wide variety of factors involved in hair loss, there’s currently no recommended fish oil dosage.  

If you use fish oil for hair loss, you should follow the fish oil manufacturer’s suggested dosage recommendations.
