Can a Low-Carb Diet Cause Hair Loss?

In today's health-conscious world, countless diet-based trends have emerged, each claiming to offer “incredible” benefits for weight loss, daily energy, and overall well-being. Among these dietary approaches, low-carb diets are probably the least surprising – having gained substantial popularity due to their effect on weight loss and blood sugar. However, as with any dietary undertaking, various questions and concerns are bound to arise at one point or another.

One such concern is whether following a low-carb diet can lead to hair loss. Hair loss, medically known as alopecia, is a distressing condition affecting millions worldwide. Understanding the potential link between low-carb diets and hair loss is essential, given the significance of our hair (in the same vein as our weight) in terms of identity and self-esteem.

Today, we’ll delve into whether a low-carb diet can cause hair loss. We'll examine the scientific evidence presented so far, explore the mechanisms behind hair growth and loss, and provide insights into maintaining a healthy balance while following a low-carb eating plan.

The Basics of a Low-Carb Diet

Low-carb diets, such as the popular ketogenic diet, the low-carb paleo diet, and the Atkins diet, emphasize reducing carbohydrate intake while increasing the consumption of proteins and healthy fats. Simple as, right? Well, that’s just the surface.

Limiting carb intake makes the body enter a metabolic state called ketosis, primarily burning fat for fuel. This process can lead to weight loss and improved blood sugar control, but its incorrect implementation can result in side effects that vary on an individual basis. While improved weight and blood sugar control are both tremendous benefits, a rushed low-carb diet can prove stressful – both on the body and the mind. Naturally, this brings us to our next point…

Understanding Our Hair

Hair growth and hair loss are indirect pointers to our body’s inner balance, or lack thereof – whether it’s hormonal, chemical, etc. A stressed body and mind can both have a considerable effect on our follicles’ health and lifespan, resulting in stress-induced hair loss or, at the very least, another element in a large heap of lifestyle problems.

Now, this isn’t to say that any of this info is exclusive to low-carb diets, nor that it is a direct indicator of low-carb diets’ effect on hair loss. Rather, it indicates that ‘any’ form of nutrient-cutting (especially abrupt ones) can hasten the natural hair-shedding phenomenon.

Exploring the Topic From a Scientific Standpoint

While anecdotal reports suggest a connection between low-carb diets and follicular loss and/or slow growth, scientific evidence on this topic is limited. However, there are several mechanisms through which a low-carb diet could potentially affect hair health.

For starters, factors such as severe calorie restriction can end up playing all kinds of tricks on our bodies. What makes this a complex topic to tackle is the symptomatic variation that’s examined from person to person. The only solidified links among patients who’ve gone on (or still go through) low-carb diets are the aspects of stress and nutrient deficiency.

The Understated Importance of Carbs

Carbs get a bad rap, and for understandable reasons. In today’s day and age, we’re prone to consuming large quantities of unhealthy carbs (sugary white bread, pastries, refined pasta) compared to their healthy variations (brown rice, legumes, wholegrain products). Experts separate the two due to the ways they affect blood glucose, cholesterol, and our gut microbiome.

Carbohydrates are a primary source of energy for the body, and what many don’t understand is that by cutting them out or severely limiting their intake, one can end up eventually reducing their passive intake of ‘other’ essential nutrients. These nutrients include B vitamins, vitamin C, vitamin E, zinc, and biotin, which are all crucial for healthy hair growth.

In conclusion, while there is limited scientific evidence specifically linking low-carb diets to hair loss, there are potential mechanisms through which such diets could affect hair health. Stress, nutrient deficiencies, and the body's adaptation to a new metabolic state are all factors to consider. Maintaining a balanced approach to nutrition, prioritizing nutrient-rich foods, and addressing any concerns with healthcare professionals can minimize the potential impact of a low-carb diet on hair health.
