Hair loss doesn’t happen instantly, it’s a gradual process that is slow and cruel, and one can’t hope but wonder about an immediate solution. Occasionally, women who become vegetarian or vegan report experiencing hair loss.

In cases where hair loss is diet-related, it may be due to rapid weight loss, thyroid problems, iron deficiency, zinc deficiency, or even the underconsumption of lysine, an amino acid.

If you feel like your hair loss is linked to the lack of a harmonious and nutrient-rich plant-based diet, the first thing you have to do is visit a doctor to understand whether or not you have a deficiency or are low in vital nutrients.

For instance, most people that go vegan increase their soy intake, but soy can affect iodine levels, especially if you’re not consuming enough iodine (about 150mcg a day).

Lack of iodine in your diet may negatively affect your thyroid, which is also associated with hair loss. At that point, an iodine supplement may help.

Alternatively, for issues that may not be diet-related, supplementation with biotin for a few months may help, which is why I’ve created this article. It’s important to separate the good biotin supplements from the bad.
