SUMMARY If your hair is thinning or falling out, it could be a sign that there’s a deficiency of one or more micronutrients, such as iron, vitamin D, zinc, B vitamins, and copper. It’s important to get tested for these deficiencies in order to address the cause of the hair loss.
SUMMARY If you are not eating enough calories and proteins found in very low calorie diets, this could lead to an unhealthy amount of hair loss.
SUMMARY When you lose weight at a very fast rate, such as from crash dieting or after bariatric surgery, it can cause hair loss.
SUMMARY If you do not have a vitamin deficiency but you are currently in good physical health but you are at risk for vitamin deficiency, you may take high dosages of certain nutrients, such as vitamin A, vitamin E, selenium, and other nutrients that are typically taken in conjunction with each other.
SUMMARY Smoking, drinking, stress, lack of sleep, and a lack of sunlight may be important factors contributing to your likelihood of experiencing hair loss.
