Does Keto Cause Hair Loss?

When you’re on a keto diet, your body enters into a state of ketosis. Ketosis is when your body is using fat for fuel instead of carbohydrates and glucose.

This process can cause hair loss in some people, but that doesn’t mean it will happen to everyone. In fact, most people don’t experience any hair loss at all while on the diet.

It’s also worth noting that there are other causes of hair loss that have nothing to do with ketosis or keto diets, like stress and hormonal changes related to menstruation or pregnancy.

If you’re worried about losing hair due to this type of diet, read more to see what may cause hair loss when starting a ketogenic diet.

You’re Not Eating Enough Calories

One of the biggest concerns people have about a keto diet is that they won’t be able to get all the nutrients, protein, and calories their bodies need while eating this way.

But if your calorie intake is low enough, especially if you’re also restricting carbohydrates (which can cause your body to burn fewer calories), then it’s possible for you to lose hair.

It’s also important to understand that it can take your body some time to adjust to this diet. That means you might experience unusual symptoms like hair loss during the transition period, and it’s not necessarily going to happen forever.

If you’re worried about losing hair on a keto diet, I recommend starting with a lower-carb approach and slowly working up to the full keto diet.

Your Body Is Dehydrated

Your body uses water to break down food into essential nutrients like vitamins and minerals, process carbs for energy or use them as building blocks for tissue and muscle, and for many other important functions, including keeping your hair growing.

If you’re not getting enough water in your diet while following a keto diet, then it’s possible that dehydration can lead to hair loss.

When you follow the keto diet, be sure to drink plenty of fluids to keep your body hydrated.

You’re Not Getting Enough Protein

If you’re eating a keto diet high in healthy fats, it’s important to ensure that you’re also getting enough protein.

Protein is an essential nutrient for building and maintaining your muscle mass. If you don’t get enough, then your body will cannibalize itself by breaking down existing tissue and muscles so that it can use them for fuel. That includes your hair tissue, which is made from protein.

If you’re eating too few calories, don’t consume enough protein or any other nutrients on a regular basis, then it’s possible to lose hair.

You’re Losing Weight Too Quickly

Losing weight too quickly is another common cause of hair loss during a keto diet. If you haven’t started losing weight, then it’s unlikely that you’ll experience any hair loss.

It’s interesting to note that when people lose weight quickly without using appropriate nutrition and exercise habits, they often find their hair falling out more than usual.

That’s because when you lose weight at a fast pace, your body uses water and existing tissue to make that happen.

When this happens, the hair can become brittle or fragile due to a lack of protein and nutrients in the diet.

You’re Missing Out On Essential Nutrients

Just like protein, your body needs certain nutrients to keep your hair healthy and growing.

Therefore, you must eat a variety of food from the different food groups while following a keto diet to get all the essential nutrients you need for good hair health.

When eating such a low-carb diet, it’s important to eat healthy fats, keto snacks and make sure you’re getting enough fiber while avoiding unhealthy carbs.

If you don’t get enough protein or nutrients from the food you eat in your diet, then it’s possible that your hair can become dry, brittle, or break off at the roots due to a lack of nutrition.

It’s also common for people to experience hair loss while transitioning into a keto diet as their bodies adjust.

If you’re not eating enough calories or getting the right nutrition, then it could be the cause of your hair loss during a keto diet.

Can You Prevent Hair Loss On Keto?

There are some things you can do to help prevent hair loss while following a keto diet.

First, make sure your body is well hydrated and that you’re eating enough protein.

Second, add more fish with healthy fats into your diet to get the essential fatty acids and nutrients like vitamin D for healthy hair growth.

Third, add more low-carb vegetables and supplements to your diet to get the nutrients you need so that your hair can remain thick and healthy. The best supplements for healthy hair contain vitamins A, C, D, E, and calcium, as well as iron or zinc.


Hair loss is rarely a cause for concern unless it becomes excessive.

Losing a little hair every day or two isn’t a problem at all. It’s normal to lose about 100 hairs each day, and your body is replacing them with new ones. If you’re losing more than usual, then make sure that you’re eating enough calories and protein in your diet.

If you’re reducing your carbs or transitioning into a keto diet, it’s normal to experience some hair loss as your body adjusts to the new nutrition and exercise habits.

This usually isn’t a problem unless you’re experiencing more than normal hair fall, such as losing clumps of hair at a time daily.

If you’re experiencing more than normal hair loss during a keto diet, then it could be due to some underlying health condition such as anemia or something else entirely different. Again, you must consult with your doctor to determine and manage the cause if necessary.

A simple blood test can help determine whether there are any serious issues involved with your hair loss.

If you’re experiencing hair falling out daily that’s more than usual, then it’s important to check for any underlying health conditions that could be the cause of your problem.
