3 Diets That Could Cause Hair Loss

They say you are what you eat. But you might not know that nutritional choices could affect hair growth. Research shows that diets lacking in essential fatty acids, zinc, biotin, iron, protein, and vitamins A, B, C, D, and E could potentially cause hair loss. Here are some of today’s most popular diets that might slow down hair growth:

1. Keto Diet

The keto diet is a low-carb, high-protein diet that could help you lose weight and improve your overall fitness. It’s become something of a fad in recent years — many celebrities and fitness gurus have lost weight on this diet.

However, some experts believe that the keto diet could cause hair loss. This is because keto places a great deal of stress on the body, which might result in malnourishment and slow down hair growth.

“Going from your normal diet to a keto diet could strain your mental capabilities if you’re already trying to micromanage other aspects of your health,” registered dietitian nutritionist Keri Gans told

2. Paleo Diet

The Paleo diet (also known as the “caveman diet”) is a diet where people eat the foods of their ancestors — foods free from genetically-modified ingredients, preservatives, and pesticides. People on the Paleo diet often consume large quantities of lean meats, such as chicken and turkey, as well as eggs and seafood.

Although the Paleo diet can help you realize your body transformation goals, it could result in hair loss if you don’t consume enough of the right nutrients. Many people on Paleo eliminate grains and legumes from their diets, which are rich in fatty acids [4]. Studies show that fatty acids promote healthy hair growth.

3. Low-Carb, High-Fat Diets

Low-carb, high-fat diets (LCHF) are similar to Keto. People on these diets will consume fewer carbs in order to lose weight and improve their fitness. The problem is, research shows that low-carb diets can sometimes result in hair loss.

Again, it’s all about stress. Calorie-restricted and carb-restricted diets can place stress on the body, which might result in hair shedding.

The latest diets might sound attractive at first, especially when fitness experts claim you can lose a great deal of weight by changing your eating habits. However, extreme dieting could hair loss and prevent hair cells from growing.
