Antioxidants and hair loss

CAN FATTY ACIDS AND ANTIOXIDANTS HELP WITH HAIR REGROWTH?

Some fatty acids are not essential; you do not need to have them in your diet because your body can make them. However, your body cannot form all fatty acids, this means that some fatty acids, like Omega-3 and Omega-6, are essential because your body cannot make them.

Antioxidants are specific substances that prevent or slow damage to the body’s cells caused by free radicals.

Vitamins A, C, E, beta-carotene, lycopene, lutein, selenium, manganese, etc. all have antioxidant properties.

HOW CAN FATTY ACIDS AND ANTIOXIDANTS HELP WITH HAIR GROWTH?

Fatty acids have anti-inflammatory effects that are important in preventing micro-inflammation of the hair follicle that can damage your hair. They also support the healthy circulation needed to transport nutrition to your scalp. Also, omegas render your hair follicles less sensitive to androgen’s hair-thinning effect.

Furthermore, arachidonic acid plays a role in promoting hair growth, by increasing the expression of growth factors, and enhancing follicle proliferation and survival.  Antioxidants work on a cellular level by preventing oxidative damage, aging, and maintaining a normal hair follicle growth cycle.

SUPPORTING EVIDENCE FOR THE ROLE OF FATTY ACIDS AND ANTIOXIDANTS IN HAIR REGROWTH

In 2015, 120 healthy female subjects participated in a 6-month-long randomized control trial to explore the benefits of fatty acid and antioxidant supplementation on hair growth. The supplements contained fish oil, blackcurrant seed oil, vitamin E, vitamin C, and lycopene.  The results proved the efficacy of this mixture in combating hair loss.  Subjects showed improved hair density, reduced telogen (resting stage of the hair growth cycle) percentage, and increased proportion of non-vellus anagen hair (growing phase of a hair follicle) with a larger diameter. Subjects reported self-perceived improvement [1].
