Nonetheless, taking too many supplements can have negative effects. Hair loss is natural, though if you are losing more than 125 hairs a day you may notice thinning. Even though hair comes in different forms and may vary between people, it is all largely made of the same materials.
Overdoing vitamins and nutritional supplements can cause hair loss. Indeed, excessive selenium, and taking too much vitamin A, have been found to cause hair loss.
Wimpole Hair Transplant Clinic says that although vitamin A is a vital part of a healthy and balanced diet, like anything, “it should be consumed in moderation”.
It states: Just because it is a vitamin does not mean that too much of it won’t do you any harm.”
It notes that the World Health Organization lists “alopecia” as a result of chronic vitamin A toxicity.
Furthermore, a study conducted in 2018, which reviews 47 other research papers on this topic, identifies excessive vitamin A as one of the most important toxic agents involved in the development of alopecia.
Indeed, it is best not to exceed the recommended limit for vitamins because too much can cause a variety of health problems.
Moreover, excessive amounts of selenium can also contribute to hair loss in some individuals.
According to researchers at the University of Surrey, consuming too much selenium creates too many antioxidant enzymes. This surplus of antioxidant enzymes causes the body to attack its own cells, including those in hair follicles, resulting in hair loss.
Despite this, for healthy hair growth, nutrients, vitamins, and minerals are essential. Indeed, the New Jersey Hair Restoration Center says the nutrient deficiencies that cause hair loss are varied.
The site says that an iron deficiency “is a very common” form of nutrient deficiency and a major cause of hair loss.
As iron helps red blood cells carry oxygen throughout the bloodstream, without enough iron, the blood cells cannot deliver enough oxygen to the body, resulting in symptoms like hair loss, brittle nails, and fatigue.
Hair Restoration also says that zinc is a “crucial nutrient for healthy hair” as it plays a “vital role in cell and immune function and protein synthesis”.
Hair loss, known medically as alopecia, is fairly common. It’s estimated, for instance, that around 40 percent of women aged 70 years or over experience female-pattern baldness, where the hair’s growing phase slows down.
Finasteride and minoxidil are the main treatments for male pattern baldness. Minoxidil can also be used to treat female pattern baldness. Women should not use finasteride.
The Cleveland Clinic says: “It is important to note that premenopausal women should not take medications for hair loss treatment without using contraception.
“Many drugs, including minoxidil and finasteride, are not safe for pregnant women or women who want to get pregnant.”
Other hair loss treatments include steroid injections and creams, as well as immunotherapy.
Some people also choose to have hair transplants, which is when hair is removed from the back of the head and moved to thinning patches.
Some wigs are available on the NHS, but you may have to pay unless you qualify for financial help.
If your hair loss is causing you distress, your GP may be able to help you get some counselling.
