2. Reasons Why You May Be Losing Hair On Keto

We all know it very well our body is extremely complex that requires verity of minerals, vitamins, and other nutrients in order to keep a healthy immune system.

All this vitamins and nutrients are fulfilled by a healthy and well-balanced keto diet.

A well-balanced diet consists of a verity of foods that have numerous nutritional properties.

But while someone adopts a keto diet to lose weight, he may deprive the body of some essential nutrients or may be reduced its consumption. This lack of nutrients, affect the health of hair.

A ketogenic diet is not only the reason of hair fall, here I have listed the several reasons that may cause hair fall.

A) Large Calorie Deficits

Studies have shown that major weight loss causes hair loss.

According to the clinical studies, it is found that a major weight loss causes hair fall.

This is because while you are on the low carbohydrate diet or in ketosis your body spends limited energy on non-vital systems like hair.

Lots of beginners, who adopted a ketogenic diet, don't replace the calories that they generally fulfill from high in carbohydrate food with protein and fats.

Usually, face a severe calorie deficit and this low-calorie diet affect the hair health.

You can avoid this by consuming the healthy and right amount of keto food.

B) Vitamin And Mineral Deficiencies

Vitamin and minerals are very essential in proper cell growth, which directly impacts hair growth.

Vitamin and minerals help to produce sebum (natural oil) on the scalp. This natural oil provides a healthy hair growth.

In ketosis due to the low carbohydrate diet less insulin produced by the body, this depletes the glycogen from our muscles.

Because of the fall in glycogen stores kidney excrete large amounts of electrolytes like potassium, zinc, magnesium, sodium and iodine.

So you have to refill these minerals and vitamins by consuming a healthy diet to get your hair healthy.

C) Stress Plays A Large Role

Whether you are on a ketosis or not stress can cause the hair loss. On ketosis because of major dietary transitions, your body experiences the high stress all time.

These are the reason your body may undergo major stress on keto:

  • Nutritional deficiencies
  • Major caloric deficits
  • Extreme calorie restriction
  • Keto flu
  • Keto rash
  • Psychological stress

D) Lack of Biotin

Biotin promotes the utilization of energy and the synthesis of proteins in our body.

A lack of biotin, cause a decrease in protein synthesis, which would restrict the production of keratin (what our hair is made of).

On studies, it is found that less carbohydrate and high-fat food cause biotin deficiency.

So it is best to take biotin supplements to prevent the keto hair loss problem.

E) Not Enough Protein

Consuming an inadequate amount of protein in the most common Keto mistake by most of the keto dieters.

A standard ketogenic food consists of high fat, moderate protein and low carbohydrates.

But many beginners mislead this moderate protein and consume a very small amount of it.

They think high protein intake can throw them out of ketosis which is not true at all.

A low carb and high protein is carnivore diet which is very helpful to keep yourself into ketosis.

According to a study report, the two main factor of responsible for hair loss is protein under consumption and calorie deficits.

However, iron deficiency also causes the hair loss problem.

F) Gut Health

The microbiome that lives in our gut has a major role in our body health, including your hair, skin and nails.

These microbiomes are useful in breaking down food.

This produces essential micro-nutrients like biotin, vitamin K, B12, niacin, and folic acid which our body requires for healthy hair, skin and nails.

So keeping your gut healthy is very important in order to prevent hair loss.

To keep your gut healthy during the ketosis your consume probiotics supplement which will help you in a healthy gastrointestinal tract.
