Factors Contributing Towards Hair Loss During Weight Loss

In our sudden rush to lose weight and get that perfect shape, we often end up following wrong practices that can affect our health, further leading to damage to hair and even hair loss. 


Our body needs a sufficient amount of all essential nutrients, vitamins, minerals, amino acids, etc., for the proper functioning of our body and hair. Lack of even one of these necessities can severely impact the growth and health of our scalp and hair follicles. This study even linked the deficiency of these nutrients to hair loss and damage. Trying to speed up weight loss, we often end up affecting our diet without caring about its effects on our health. 

Extreme protein cut-off

Amino acids present in protein are the most essential requirement for the formation of keratin present in your hair that strengthens your hair follicles and promotes healthy hair growth. Lack of protein in your diet can lead to acute hair loss. As per a study about the low-calorie diet, if your body has a low amount of protein, functions such as tissue repair, digestion of food, and hormone production take priority over the care of your hair. 

Overdoing physical exercise

We often combine physical activities like going to the gym, Zumba, Pilates, etc., with dietary changes with the purpose of losing weight at a fast pace. A condition of excessive hair loss called alopecia areata can be caused due to a shock reaction triggered by our body when we are dealing with extreme fatigue. 

Crash diets

Several pieces of research have created a direct link between crash dieting and alopecia. Crash dieting leads to a lack of essential nutrients and calories in your body and causes several psychological issues and extreme stress. Adopting a crash diet won't make you look good; instead, it would cause several irreparable damages to your body, as well as your hair.
