Does coffee cause hair loss?

In this article, we will answer the question: “Does coffee cause hair loss?”. In addition, we will discuss coffee’s relationship to hair loss and the difference between coffee and caffeine and how it impacts hair loss.

Does coffee cause hair loss?

It could be, because some compounds in coffee impair the absorption of some nutrients, impairing capillary health.

Several scientific studies are showing that coffee has a negative effect on the absorption process of minerals and vitamins of the B complex, essential nutrients for the production of beautiful and healthy hair.

Coffee hinders, above all, the absorption of iron, and in this sense, women end up being the most affected, because women menstruate, get pregnant, breastfeed, etc., and all these situations reduce iron reserves in the female body.

In addition to iron, coffee also impairs the absorption of zinc, magnesium, calcium and even vitamin D, which in the long run can lead to diseases such as osteoporosis.

Why is drinking coffee not good for your hair?

According to some scholars, drinking too much coffee can lead to increased arrhythmia, gastrointestinal problems and insomnia. In addition, a high level of caffeine circulating in the bloodstream increases levels of cortisol, a hormone present in the body, and this speeds up somewhat the process of skin dehydration and aging.

In other words, since coffee is a vasoconstrictor, it contributes to decreasing the performance of the arteries, which favors poor blood circulation. And this ends up causing the hair to not receive all the nutrients it needs to stay strong and healthy.

Can caffeine help?

First of all, we need to clarify that coffee and caffeine are two completely different substances. Coffee is a beverage produced by filtering water through ground roasted coffee beans, while caffeine is a natural chemical stimulant commonly found in tea, coffee, soft drinks, energy drinks and chocolate.

The fact is, caffeine can benefit your hair’s health in many ways! So, you might be wondering “if I drink enough coffee, which contains caffeine, will my hair stop falling out?” The answer is no!

Caffeine is a known stimulant contained in coffee, whose effects are mainly mediated through the inhibition of phosphodiesterase, which leads to increased activity of the intracellular adenylate cyclase enzyme and increased levels of adenosine 3′,5′-cyclic monophosphate (cAMP).

Thus providing higher energy levels to promote increased metabolic activity and cell proliferation may be associated with the containment of hair follicle shrinkage in patients with androgenetic alopecia (AGA) better known as male hair loss.

Home treatments can help prevent falls. A German study points out that hair growth can grow up to 25% more when the coffee powder is applied to the scalp.

But beware: the research was done with a synthetic substance called Caffeine Anhydrous, which has nothing to do with the coffee powder you buy in the market.

Coffee is a natural stimulant and, because of that, it is not surprising that it also enhances growth in the hair region. When it is placed in our hair, there is an increase in blood circulation and hence the hair grows faster.

In addition, a study published in the International Journal of Dermatology, in England, showed that caffeine blocks DHT, the hormone responsible for baldness and that acts inside the hair follicles, causing the cells that produce the hair to die.

The follicles that were treated with caffeine had a 46% improvement in their growth compared to the control group, and their life cycle was extended by 37%.

According to a survey carried out by German dermatologists at the University of Lubeck, coffee can be an important ally against baldness. According to the study, the substance can encourage 25% faster hair growth, also contributing to the increase in hair volume.

Scholars still argue that women can benefit even more from the novelty, as female hair follicles stand out for being more sensitive and reacting more quickly to treatment than males.

Caffeine enters this context as an ally for having a high capacity to penetrate the skin barrier. Therefore, it is being used more and more in cosmetics, in formulations that vary from 1% to 5%, depending on the product’s purpose. 

The substance acts in the same way as finasteride, inhibiting the 5 alpha-reductase enzymes, responsible for the production of the hormone DHT, which makes the hair thinner.

However, those who want to use homemade recipes to benefit must be aware: experts indicate that the coffee used in our homes does not have enough quantity to guarantee the effect. To achieve the dreamed results, it is preferable to use special hair care products that already have caffeine in their formula.
