Hair loss, also known as alopecia, is a disorder caused by an interruption in the body’s cycle of hair production.
Hair loss can occur anywhere on the body, but most commonly affects the scalp. On average, the scalp has 100,000 hairs that cycle through periods of growing, resting, falling out, and regenerating.
If this cycle is disrupted, or if a hair follicle is damaged, hair may begin to fall out more quickly than it is regenerated, leading to symptoms such as a receding hairline, hair falling out in patches, or overall thinning. It is typically linked with genetics, hormonal changes, and medical reasons.
Recently the question “do vegans lose their hair?” has become prevalent.
The short answer is – yes it can.
But the truth is that any diet that causes a lack of nutrients can result in hair loss.
Diet plays an important role in keeping the skin and hair healthy. The foods we eat have an impact on the growth, strength, and volume of our hair. Hair grows from the roots, so the key to healthy hair growth lies in improving the health of the scalp and hair follicles.
Making sure you get enough iodine, by taking 75 to 150 µg per day from a supplement, should prevent any hair loss problems that could be due to iodine or soy. If you have a mild thyroid condition, limiting soy might also help. If you take synthetic thyroid hormone, speak to your doctor about a healthy amount of soy.
Other nutrients that help with hair growth:
Biotin. Lentils are a good source of biotin—a nutrient that has been shown to promote hair growth.
Omega-3 Fatty Acids.
Eating a healthy, balanced plant-based diet, rich in whole foods, is beneficial for your hair because it’s high in essential vitamins and minerals, says physician Dr. Angela Eakin. It may reduce the risk of hair loss and help you grow stronger, healthier hair.
