The Hair Growth Cycle

We think hair is just a strand of specialized tissue of our body but there is a lot that is going underneath this strong tissue. First of all, you need to understand the anatomy of hair;

It contains two characterized structures;

The hair follicle: It is the part of the hair which present deep in the skin from where the hair growth stimulates or stops which usually depends upon the nutrient availability and chemical nerve message received by the body.

The hair shaft: This is the hardware part of the hair which you can see and touch, it is formulated of a protein known as keratin which is combined to make a strong hair strand.

Three hair follicle phases determine hair growth, loss, and regrowth.

The Anagen phase:

It is the phase of hair growth during which the hair grows about 1 cm in every y28 day’s interval, as a result, the old hair pushes up and out of the follicle point. The origin of the hair follicle determines the duration of the anagen phase such as the scalp hair stays in the anagen phase for 2 to 6 years.

The Catagen phase:

It is the phase of transition and change where hair growth stops for two or three weeks.

The Telogen phase:

It is the resting phase where the hair growth stops for almost 90 to 100 days. Only 5 % to 8 % hairs out all the percentage are in this phase while the remaining is still in the growth process. Generally, 50 to 100 telogen hair sheds per day.

Any lifestyle change can cause these phases to change which ultimately results in hair loss.

Keto Diet and Hair Loss: Your Body’s Response

Usually, your body uses carbohydrates to fulfill its energy requirements but when you go on a high-fat and low-carb diet like keto the energy production process shifts to ketosis, which is a metabolism that utilizes fat to fuel the body. This a big change that the body goes through so it takes time to get adapted to it and also it can cause some situations that do not happen before like hair loss.

Few aspects of the ketosis process can stimulate hair loss and downfall in the health of hair follicles. Following are the most common reasons for hair loss during the keto diet:

Body’s response to exclude calories:

When the body gets fewer calories than normal for its functioning, it starts to prioritize the important systems and functions like the functioning of lungs, heart, and other organs, also for cell development. So, the body decides to give less energy to hair for growth as it is not as crucial as breathing.

Lesser nutrients availability:

On a keto diet, you reduce the intake of carbohydrates which includes various vegetables, fruits, dairy products, . In this whole scenario, you may also limit the nutrients that are needed for hair growth and maintenance. This can slow down the hair growth process or cause your hair to shed more than normal.

Common Keto Hair Loss Causes

The common causes of keto hair loss are:

Inadequate protein consumption:

If you consume low protein content on keto, which is already deficient in carbs can cause weight loss from your muscle and hair. One study was oriented about it and results was quite clear that inadequate protein consumption and Calorie restriction are two fundamental cause of hair loss.

Gut health problems:

Gut health is directly related to all the major systems of the body including hair growth, if you having gut issues, it can increase the stress levels which ultimately results in hair follicles stopping their growth. A few medical studies have concluded that the microbiome of the gut also stimulates the production of biotin which is an important hair nutrient, so the gut disorder can reduce hair growth by not getting enough nutrients.

Sudden drop in carb consumption:

A sudden drop in carb consumption is a major change in the body as the energy source shift to fats metabolism (ketosis), this change can cause higher stress levels and nutrient imbalance that can result in hair loss.

Major calorie reduction:

When your body receives fewer calories than usual, it starts to prioritize the major systems like heart, lungs, for the available energy and in this whole situation, the hair growth gets neglected which will result in hair damage and breakage.

Micronutrient’s deficiency:

A keto diet can restrict a few key vitamins and minerals which are essential for hair growth, so due to micronutrient deficiency, your hair growth can get affected.
