Post Covid-19 hair loss?

I have noticed that since contracting Covid a number of my clients have complained about excessive hair loss. In this article I am going to talk through the root causes of hair loss and how can we help to strengthen our hair follicles and regain hair growth.

Telogen effluvium is a form of temporary hair loss that usually happens several months after a person experiences a traumatic event or stress. A study found that it occurs in 66% of people who contacted COVID-19. Ferritin (the storage of Iron) is removed from the body post infection. The infection causes inflammation in the body resulting in an increase of hepcidin (a protein which regulates the entry of iron into the circulation of mammals). Increased concentration of Hepcidin impairs dietary absorption of Iron which further affects hair follicles1.

This can lead to anaemia. Check with your medical practitioner first before you decide to take Iron supplements. Natural sources of Iron include: red meat, liver, legumes and pulses such as red kidney beans, peas and lentils and dark green vegetables such as kale and spinach.

Hair loss is also associated with immune nutrient depletion. White blood cells need nutrients such as vitA and Zinc to help our body fight infection. These also help to improve thyroid function and thyroid hormone production. Deficiency of these nutrients can affect our thyroid health and thyroid hormone levels. Prolonged and severe hypothyroidism and hyperthyroidism can cause hair loss.

The immune system requires folate (known as vitB9) especially follinic acid (naturally found in food). Depletion of this can cause the hair follicle to become undernourished and weak resulting in hair loss. Folate helps to promote hair growth and add volume2. Good food sources of folate include: liver, seafood, dark green leafy vegetables, sunflower seeds, eggs, beans and whole grains.

Stress is a big contributor to hair loss. When fighting severe infections such as COVID-19 our body is put under significant stress. It is not only depleted of nutrients but also stress compromises the digestive system. Stress reduces our stomach acid production (hydroloric acid) which is essential for sufficient digestion of food and key nutrients. Some of the nutrients such as Vitamin K, B12, B3, folic acid and biotin which are essential for hair cycling and growth. Low hydrochloric acid levels can affect your stomach’s ability to digest and absorb proteins. It can also damage your gut and lead to digestive health issues and infections. You can naturally improve your stomach acid production by incorporating apple cider vinegar in your diet.

Raw apple cider vinegar can increase stomach acid levels because its acidic properties introduce more acid into the digestive tract. Other than increasing stomach acid levels, raw apple cider vinegar has been associated with reducing symptoms from acid reflux, diabetes, and high blood sugar3. Zinc is an essential mineral present in human cells. The stomach uses zinc to produce HCL. Addressing a zinc deficiency could help increase stomach acidity. Some Zink-rich foods include: oysters, beef, nuts and seeds. Your medical practitioner may also prescribe supplements such as betaine hydrochloride to restore the pH of your stomach.
