Can Foods Cause Hair Loss?

Yes, certain foods can contribute to your hair loss, while some can help prevent it. When you overconsume some foods, they can cause inflammation, disturb your hormonal balance [2] , and deliver poor nutrition to your scalp. This can eventually affect your hair growth cycle and lead to hair shedding. Let us learn about the foods that cause hair loss in the section below.

What Are the Foods to Avoid for Hair Loss?

Here is a list of foods that cause excessive hair fall and hair thinning:

  1. Dairy Products

Consuming dairy products can contribute to hair fall, especially if you are susceptible to dandruff and other scalp issues. We all know that dairy contains some amount of fat. When you overeat dairy products, it can increase testosterone or DHT levels in your body. This action further triggers inflammation, damages your hair follicles, and leads to hair loss. Dairy products are one of the foods to avoid for hair loss. Make sure you eat them moderately.

  1. Sugar

When you overeat sugary foods, they can increase insulin levels in your body, which can lead to hair thinning or hair loss. Apart from that, sugar also increases testosterone levels in your blood, which can cause hair loss. So, it is always advisable to avoid sugar as much as possible.

  1. Refined Carbs

There is a connection between refined carbs and hair loss. When you consume refined or simple carbohydrates, such as bread, pizza, pasta, cakes, and other foods, it can raise insulin levels in your blood. It can also cause inflammation and increase androgen levels, resulting in hair thinning. These are one of the foods to avoid for hair loss.

  1. Greasy Foods

Admit it or not, we all love oily foods. Here is the truth. Consuming greasy or fried foods in large quantities can contribute to your hair loss. These foods can stimulate the sebaceous glands in your scalp to produce more oil, making your scalp oily and sticky. An oily scalp means clogged pores, which can lead to hair thinning and slower hair growth.

  1. Carbonated Drinks

While we all prefer carbonated drinks, no matter the occasion, they can be harmful not only to our health but also to our hair. These drinks contain high levels of sugar [3] , and overconsumption can lead to insulin resistance. It also triggers inflammation and disturbs your hormonal balance. All of this can affect your hair follicles, eventually leading to male pattern hair loss.

  1. Alcohol

Excessive alcohol [4] consumption is another contributing factor to hair loss. Heavy drinking can cause nutritional deficiencies and hormonal imbalances, which can lead to hair thinning or hair loss.

  1. Artificial Sweeteners

While there is no direct link, artificial sweeteners such as aspartame and others can contribute to hair thinning. Often found in sodas, sugar-free drinks or products, overconsumption of these sugar substitutes can affect your hair growth cycle.

  1. Food Additives

Certain food additives can trigger hair loss in individuals, especially when consumed in excess. These additives can cause inflammation and disturb your hair growth cycle, leading to shedding of hair.

What Are the Tips to Prevent Hair Fall?

While some foods can trigger hair loss, others can promote hair growth. Including certain foods in your regular diet can strengthen your hair and prevent hair loss. Here is a list of foods you should incorporate into your balanced diet to maintain hair health:

  1. . Protein-Rich Foods

Eggs, lean meat, fish, beans, lentils, legumes, nuts and seeds
