How to Prevent Hair Loss during Weight Loss?

Did you know sometimes weight loss can have a negative impact on your body and even cause hair loss?

When you intend to achieve an abrupt weight loss journey, you are likely to encounter nutrient depletion, stress, and hormonal changes that can lead to hair loss.

In this article, we will discuss why hair loss occurs and how to prevent hair loss during weight loss.

What can cause hair loss post-weight loss journey?

The nutrient deficiencies due to weight loss cause hair loss. Instantaneous weight loss can have even more effects on your body.

Acute Telogen Effluvium (TE) is related to prohibitive diets and accelerated weight loss. TE is a general foundation of hair loss on the scalp. Following a triggering experience in the human body, like weight loss, TE arises 3 months post the incident and stays for almost six months.

These are the reasons that interconnect hair loss and weight loss.


Our hair also requires a sufficient amount of nutrients to grow properly. So, when our body is deprived of essential nutrients, side effects, including hair fall, can occur.

Several types of research have associated hair loss with sudden weight loss due to all the aspects present in a person following a crash diet that includes nutrient inadequacy, calorie constraints, and psychological stress.

Deficiency of essential nutrients means inadequate consumption of essential fatty acids, zinc, protein, and calories that occur as a result of an imbalanced diet, carelessly planned diet, or crash diets which eventually lead to hair loss.

Poor Protein Diets

When your body is deprived of the proper amount of protein, it is known as protein malnutrition. Low consumption of protein can prompt hair fall. A person who follows a low protein diet is inclined to encounter hair loss.

The vital organic protein for hair growth is keratin, which is built from amino acids. Amino acids are the building blocks of protein.

There are numerous protein-reliant procedures like tissue restoration, digestion, pH and water balance regulation, hormone creation, and hair growth.

When furnished with low protein levels, the body neglects hair growth and reparations and looks after other functions as other processes are more significant for human life.

Weight loss surgeries

People often opt for weight loss surgeries to obtain instant weight reduction. These procedures generally lead to a shortage of nutrients which eventually triggers hair loss.

As per an analysis, 112 women received sleeve gastrectomy, a procedure that involves subtracting a large fraction of the stomach. Post-surgery, 72% of them faced hair loss. Many of them were seen experiencing hair loss 3-4 after the surgery that continued for 5-6 months.

Weight loss surgeries heighten the threat of deficiencies by allowing the food to pass into the region of the intestine that prompts malabsorption of the nutrients.

Exclusive Diets

The selective diet is similar to a crash diet as it removes an entire food group that causes stress and malnutrition.

Hair loss is reported to have occurred due to deficiency in numerous nutrients like iron, protein, selenium, fatty acids, zinc, and even improper amounts of calories are also related to hair loss.

Major stress that comes along with a restrictive diet is harmful to health, including your hair health.

So, the question arises of how to prevent hair loss when working on weight loss.

How can I keep my hair from falling out when I am losing weight?

As aforementioned, the major hair loss cause during the weight loss process is the deficiency of essential nutrients. As a result, it is significant that you attempt to lose weight healthily.

How dangerous is hair loss after weight loss?

Hair loss is not harmful after weight loss, but it can be harmful in other ways. For instance, nutrient deficiency will not only impact your hair development but can also harm you physically.
