Caffeine is more than just the ingredient that powers your morning coffee—it’s also an increasingly popular component in hair care. It has the power to promote hair growth. An increasing number of people are asking, how does it affect hair and can it help promote hair growth? Check out what science has to say about this secret weapon or a head full of thicker hair as we dive deeper into the world of caffeine and its role in hair and scalp health, given that all our products are claiming it too!
Caffeine and Hair Growth: The Science
One of the key mechanisms by which it affects hair growth is by being an inhibitor of phosphodiesterase. This enzyme normally breaks down cyclic adenosine monophosphate (cAMP), which is crucial for stimulating hair follicles and promoting growth. By inhibiting phosphodiesterase, caffeine helps increase cAMP levels, potentially leading to enhanced hair follicle activity and better hair growth.
It also has DHT-blocking properties. DHT (dihydrotestosterone) is a hormone associated with hair loss, especially in men. Reducing DHT levels could mean fewer hair follicles shrinking and falling out. You might wonder, “Does coffee block DHT?” While drinking coffee may have some marginal effects, it’s topical caffeine products that are most effective for targeting the scalp directly.
However, it’s important to recognize why lab results may not always reflect real-life effects on human hair growth. The experiments were conducted in vitro (in a controlled lab environment, such as a petri dish), which means the results may not fully translate to real-world hair growth. In vitro studies provide valuable insights, but they don’t account for the complexities of the human body, including how substances are absorbed, distributed, metabolized, and excreted (pharmacokinetics and pharmacodynamics).
Additionally, while hair continues to grow even on cadavers, the biological processes in a living person are far more intricate. As a result, in vitro findings should be interpreted cautiously, as they may not guarantee the same outcomes in actual human use.
Caffeine in Hair Products: What to Look For
The popularity of it in hair care has led to caffeine-infused hair products. From caffeine hair oil and caffeine drops to caffeine-infused shampoos and hair serums, there are plenty of options for incorporating it into your daily routine. The best caffeine shampoo for hair growth is one that combines it with other key ingredients, such as biotin or peptides, to deliver nutrients directly to your scalp and hair follicles.
For example, the Inkey List peptide volumizing hair treatment is designed to volumize and strengthen hair using both peptides and caffeine. Other notable products are Alpecin liquid and Alpecin Caffeine Shampoo C1, which are known for their content aimed at fighting hair loss. However, it’s important to note that Alpecin Caffeine Shampoo C1 side effects may include scalp dryness or irritation, so always patch-test before regular use.
Does it Promote Hair Growth?
Many studies support the idea that topical it can promote hair growth. Caffeine oil is essentially a carrier oil, such as coconut or argan oil, infused with it. The idea behind it is to harness the stimulant properties of it. When it is applied to the scalp, it penetrates the skin and stimulates blood flow to the hair follicles. It boosts the delivery of oxygen and nutrients. This improved circulation can extend the growth cycle of the hair, and keep healthy hair development.
But the effectiveness of it isn’t just limited to oils and serums. There are even caffeine hair sprays, which provide a light, daily boost to your hair follicles. These sprays are typically water-based hair growth serums, making them easy to apply without leaving a greasy residue.
If you’re asking, “Is caffeine good for hair growth?” or “Does coffee help hair growth?” the answer, in short, is yes—but mostly when applied topically. Consuming it orally, as in coffee or energy drinks, doesn’t directly benefit your hair. Excessive caffeine intake can lead to side effects like hair loss, especially in those who are sensitive to it. So, if you’re someone who drinks a lot of energy drinks, you might want to consider whether it’s contributing to hair loss.

Coffee and Hair Care: A DIY Approach

In addition, you might have read somewhere that coffee after a hair transplant can also help to accelerate the healing process, while also supporting stronger and healthier new growth from your hair.
Caffeine vs. Minoxidil: Which is Better?
A common question is how caffeine compares to minoxidil, the well-known hair growth treatment. Both are topical treatments aimed at stimulating hair follicles, but they work in different ways. Minoxidil is FDA-approved for hair loss and works by dilating blood vessels around the scalp, thus improving hair growth. On the other hand, it is a more natural approach that blocks DHT and stimulates the hair growth cycle, though its effects may be more subtle compared to minoxidil.
It is a debate for those exploring treatment options, some prefer to use them together. Certain products combine both ingredients for maximum stimulation of the hair follicles, addressing both hormonal and circulation-based causes of hair loss.
Caffeine Products for Men and Women
Caffeine isn’t just for men experiencing hair loss. Women can also benefit from using it hair care products, although there are some nuances. For instance, many ask if Alpecin can be used by women. While Alpecin primarily markets to men, it is safe for women to use. However they need to know that applying caffeine on the scalp may cause dryness, so it is advisable to apply it in combination with moisturizing treatments.
Alopecia shampoos for women are products that are used to help treat hair thinning and loss as a result of diseases such as alopecia. Most of these shampoos contain things like caffeine, biotin, minoxidil, and DHT blockers to help stimulate hair growth. Some of the common brands are Alpecin Caffeine Shampoo for women and other shampoos for breakage and hair loss.
If you’re searching for a caffeine-based hair regimen, be sure to consider your hair type and specific needs. From caffeine hair conditioners to everyday hair growth serums, products are suitable for all hair types and conditions.
