Before we jump into this topic, it is important to note that just because social media tells you that you should go on a diet, or a celebrity is endorsing a weight loss program doesn’t mean that you should go on a diet. If you are about to embark on a weight loss journey, it is important to note that according to the NHS website sudden (and even gradual) weight loss can cause your hair to fall out. It is also possible that emotional or physical stress can lead to weight loss which can also trigger hair falling out. Thus, you should watch out for when you’re in your down moments to help you determine the trigger for your weight loss and subsequent hair loss.

Weight loss and hair loss can go hand in hand. The more weight you lose in a short space of time by restricting your calorie intake, the more hair can fall out. It’s all about nutrients. Lack of adequate proteins, iron and other dietary supplements in the human body can lead to hair loss.

When we don’t supply our bodies with the correct or required supply of nutrients, especially proteins for its body building and repair duties, it sets into the “intelligent” mode where it by its self, rations the amount each part of the body can get from the insufficient nutrient supply.

Bad news: your body doesn’t think too highly of your hair because your hair isn’t crucial to your survival. So, our hair becomes protein- thirsty and deprived of their desired nourishment, which can lead to it looking dull, dry and in drastic cases falling out.

How can you lose weight without impacting your hair?

The following tips will guide you.

  1. Consult your doctor before you go on any diet
  2. Stay away from crash diets, juicing diets, detoxes, appetite suppressants and all the other faddy diets out there. No matter who is endorsing them, they aren’t healthy or sustainable.
  3. Proteins are essential for your hair, skin, and nails. Ensure you are getting an adequate amount. your hair is made of proteins, so this will drastically help your hair health.
  4. Incorporate veggies like broccoli and spinach, fruits like avocado and fig,  eggs and lean meats, and other foods like beans, citrus fruits, and whole grains into your diet for healthy contribution to your body.
  5. Don’t deny your body adequate supply of calories; they help in promoting proper functioning of the body. You can be mindful of your calories consumption for your weight loss goals but don’t go overboard. It will tell on your hair.
