It is unlikely that your hair loss is due to food and nutrition. However, hair loss can be due to:
-
An extremely poor diet that is very low in protein and calories.
-
Being low in certain vitamins and minerals may contribute to hair loss. Deficiencies in vitamins and minerals that have been associated with hair loss include: B vitamins, vitamin D, iron and zinc .
-
Crash diets, eating disorders or starvation.
-
High intakes of certain supplements like selenium, boron or vitamin A.
Hair loss can happen for many other reasons as well such as:
-
Too much colouring, shampooing, straightening and blow drying
-
Wearing tight braids, rollers, ponytails or hats often
-
Medication or chemotherapy
-
Surgery and certain diseases like PCOS, Crohn's disease, celiac disease, ulcerative colitis, or chronic kidney disease
-
Stress
-
Pregnancy and childbirth (note: hair loss often returns to normal 6 months to 2 years later)
If your hair loss seems sudden or severe or if you have concerns about your hair loss, speak to your health care provider. Talk to your dietitian or health care provider before taking any supplements as taking high amounts of supplements, like zinc, may be dangerous. Following Canada’s Food Guide will help you make healthy and balanced food choices to give you the nutrition you need.
