What is caffeine?

Caffeine is a natural stimulant that has made its way into various products. It has been around for thousands of years and ranks as one of the top active food ingredients most commonly consumed worldwide.

One can find varying caffeine traces in beverages (such as coffee, tea, or soft drinks), prescription or over-the-counter drugs, supplements, and even skin and haircare.

Learn more about this ingredient and the gains it poses for one’s strands.

What does caffeine do to human health?

Naturally found in coffee beans, cacao beans, kola nuts, guarana berries, and tea leaves, around 80% of the world’s population consumes caffeinated products daily.

Caffeine is the common name for 1,3,7‐trimethylxanthine. It is derivative of the German word, kaffee, and the French word, café, which both mean coffee. The first discovery of coffee dates back to the 9th century in Ethiopia when an Ethiopian shepherd noticed that wild coffee berries gave his goats more energy.

However, historians disclaim this origin, saying that Chinese Emperor Shen Nung discovered caffeine as far back as 2737 BC when he boiled drinking water and leaves from a nearby bush. The result produced a delightful aroma and the first pot of tea.

Nowadays, there is a whole category of functional beverages, most notably soft drinks and energy drinks. Consuming caffeine in moderate amounts is generally safe. It is quickly absorbed in the bloodstream, traveling to the liver until it breaks down into compounds affecting several organs. But, it is the brain that feels caffeine’s effect the most. Many can attest to its performance benefits, including:

  • It increases physical endurance, reducing fatigue.
  • It enhances mental alertness and concentration.
  • It may improve mood, decreasing the likelihood of depression.
  • It stimulates brain function, protecting against Alzheimer’s and Parkinson’s disease.
  • It may boost metabolism and fat burning.
  • It helps increase blood circulation.

Numerous regulatory agencies around the world approve of its use as a food ingredient. Because of its advantages on human health, caffeine has become a popular component in cosmetics and hygiene products, especially for the hair.

Why is caffeine good for hair?

Due to its stimulating properties, caffeine is used on hair to help promote hair growth. It targets the roots in hair growth’s initial phases, targeting a hormone called Dihydrotestosterone (DHT). DHT is an androgen that can prevent the hair follicles from getting sufficient vitamins, proteins, and minerals, causing one to lose their hair faster and earlier.

Research shows that caffeine combats hair loss by inducing hair cells to produce more Adenosine Triphosphate (ATP). It is a molecule that carries energy to encourage the cells to grow hair. Caffeine also helps speed up the hair growth cycle and, according to a study, increases hair length from 33-40%. But more supporting medical evidence is needed to back up this claim entirely.

With increased blood circulation, caffeine promotes healthy hair follicles as more nutrients reach the hair’s scalp and roots — the stimulation and nourishment results in faster, healthier, and stronger hair growth.

What are the benefits of using caffeine shampoo?

Many people can profit from caffeine’s benefits on hair, especially with the high prevalence of alopecia (hair loss) and hair thinning on both men and women. The first-ever caffeine shampoo came into existence back in 1905.

Like the newer caffeine shampoo to date, they are all designed to penetrate the skin, dousing the hair follicles and re-invigorating the hair. It swiftly courses through the hair shaft and directly to the hair follicles. Washing hair with the product and leaving it on the hair and scalp for at least two minutes (preferably longer), even after rinsing the caffeine shampoo out, will have anyone reap the following benefits:

  • It may prevent genetic hair loss and other types of hair fall.
  • It cures a few scalp related problems (i.e., dandruff, itchy skin, and weakening of hair)
  • It aids in strengthening the hair follicles from the inside.
  • It adds volume to hair.
  • It improves the quality of hair.
  • It helps enhance hair color.

FAQs on caffeine shampoo

Just as many are ecstatic to try caffeine shampoo, those who have a particular sensitivity to the ingredient often have reservations about trying it. Here are a few answers to the frequently asked questions on caffeine and caffeine shampoo usage:

Is there anyone who should NOT use caffeine shampoos?

Caffeine is a relatively safe ingredient, and it usually is only used in minuscule percentages in products. With most caffeine shampoos, any scalp or hair type can use them without side effects. As a precaution, it is best to still check the label before purchase or consumption.

Can caffeine cause hair loss?

Caffeine, on its own, presents several health benefits, but, as with most things (including vitamins and antioxidants), too much of it can negatively affect one’s overall health and adversely affect the hair’s growth cycle by slowing it down.

With a caffeine shampoo, the percentage of this active organic ingredient is relatively small, so one cannot technically go overboard on the dosage. Be careful not to use too much of the product in any case as it may lead to product residue. Consult a dermatologist before mixing products to avoid overloading your hair. Or you can purchase a pre-mixed product that is safe to use.

How often should I use caffeine shampoo?

It is safe to use caffeine shampoos every day or as often one would typically wash their hair. However, depending on the chosen caffeine shampoo brand, one should double-check the labels for possibly harmful chemical ingredients. Also, make sure that the product is specifically for their scalp and hair type. 

How long before I see desired results from caffeine shampoo?

While there is evidence of caffeine stimulating hair growth and preventing hair loss, experts conclude that more research is needed to determine the full range of its effects. Results will also vary depending on the product used and on the individual using it.

For better hair health, one must also consider lifestyle and medical conditions (if any). If one is suffering from hair loss, especially if it is sudden or unexpected, seek immediate consultation with a health care professional.

Does caffeine shampoo affect my testosterone levels?

The caffeine in the shampoo will only protect the hair roots against the effects of testosterone. It cannot change the levels of testosterone in the body.

Will caffeine shampoo keep me awake or disrupt my sleep at night?

The caffeine and any other active ingredients in it will only reach as far as the root of the hair follicle. Using the product as directed will not affect the rest of the body, and its effects are only local to the scalp (and the hair strands to a certain extent).

Is drinking caffeine better than applying it topically?

Unfortunately, drinking coffee will not affect the hair or hair growth unless consumed in copious amounts (which may lead to hair loss or thinning). For best hair results, apply caffeine directly on the hair and scalp with a shampoo that is apt for one’s scalp and hair type and minimal or no harmful chemicals.

Does caffeine shampoo work?

Caffeine is an organic ingredient that presents many health benefits, particularly as a stimulant, so long as it is consumed reasonably. As a component in shampoos, it can promote healthy hair growth and prevent hair loss.
