Can coffee cause hair loss?

Coffee does not directly cause hair loss. Excessive consumption of caffeine in any form, such as coffee, can cause anemia. A common symptom of anemia is hair loss. According to the FDA, the safe limit for coffee is 400 mg a day. However, safe limit tends to vary from person to person, with the account to factors like age, health, and sex.

Contrarily, caffeine in safe limits promotes hair growth and contributes to healthy hair. It is also gaining popularity as a topical treatment to combat hair fall in men and women.

Some studies have shown the relationship in improving the hair in males and females by topical application of coffee. The experiments proved people in the studies to have longer and wider hair roots. A similar effect could be achieved by drinking moderate amounts of coffee. However, the same level of result attained by the topical application can not be attained by oral consumption to the same extent. 

How can caffeine prevent hair loss?

Some noteworthy and significant research has been done which points towards improved hair growth by caffeine.

The sex hormone dihydrotestosterone (DHT) can cause hair fall in both men and women, is inhibited by caffeine. Another hormone called androgenetic alopecia (AGA) is responsible for male pattern baldness is also suppressed by caffeine. 

The growth of hair occurs in three significant phases; anagen, catagen, and telogen. The three stages of hair growth are crucial and regulatory factors such as a hormone.

DHT attaches itself to hair follicles and prevents nutrients from reaching the roots. Coffee stimulates hair growth by improving blood circulation. Caffeine increases shaft elongation, prolongs the anagen phase, and improves the hair matrix keratinocyte proliferation.

The anagen phase is the last of hair growth, which lasts 2 to 7 years. Here, the hair grows from the roots until the hair follicles become dormant. There are other factors besides the role of caffeine, which could cause the length and span of hair growth to vary.

Caffeine has been proven to benefit hair by promoting growth and preventing alopecia. Caffeine has a positive effect on hair growth by stimulating the hair follicles and protect hair. 

Caffeine inhibits PDE enzymes and stimulates cell proliferation. The cell growth increases and makes hair healthy.

How can coffee indirectly contribute to hair loss?

Hair loss is caused by numerous factors; some of which include, stress, anemia, poor diet, genetics. 


If you experience sensitivity toward caffeine, including poor overall health, then coffee could be a contributing factor. 

Even genetic makeup can affect how a person reacts to caffeine. The enzymes which break down the caffeine in the liver can vary and, so can the neuroreceptors which respond to caffeine. The above factors can make the safe or recommended dose vary from one person to another.

If a person experiences symptoms like palpitations, anxiety, dizziness, insomnia, and GIT discomfort, it could mean that you are experiencing caffeine sensitivity. Some symptoms are less obvious such as hair loss. 


Anemia is more common in women than men and, there could be multiple factors that contribute. Anemia could be the result of a poor diet or a family history. However, it is not always difficult to handle. Making lifestyle changes could help with anemia, such as limiting caffeine intake. You can try reducing coffee and consider the impact on your overall health, including your hair.

Pregnant women are at a greater risk of suffering from anemia and consequent hair loss. You need to cut back depending on your age, health, and some other relevant factors.

How to benefit from coffee and combat hair loss?
