Benefits And Safety Of Caffeine
Over the last decade, more and more publications have emerged that associate ingestion of coffee with beneficial effects in various diseases, covering dementia, liver diseases, diabetes, several types of cancer, and skin conditions as referred to in this paragraph. While it is not always clear if these effects are specifically due to caffeine or due to other substances or combinations of substances contained in coffee, several studies have found a specific association of positive effects of coffee ingestion with caffeine.
In general, oral caffeine consumption is safe for healthy adults at doses typically found in commercially available foods and beverages . However, very high doses of ingested caffeine can produce undesirable effects on mental functions such as fatigue, nervousness, and feelings of anger or depression. The European Food Safety Authority concludes that for healthy adults daily intakes of up to 400 mg per day do not raise safety concerns . Caffeine is well known for its excellent skin penetration properties: In cosmetic formulations, caffeine is currently in use in concentrations up to 30 mg/mL , whereby caffeine penetration through the skin is independent of the skins thickness .
Does Caffeine Shampoo Work
It is unclear. Whilst the study above showed that caffeine does stimulate hair growth in a laboratory dish there is not enough evidence to prove it works with hair on the scalp.
There is a lot of debate surrounding whether caffeine shampoos can actually match the success of this initial study to prevent hair loss. Generally speaking, caffeine shampoos are not endorsed by the medical community to treat hair loss. Instead, most UK doctors recommend medical treatments such as finasteride or minoxidil, which have been proven in clinical trials.
Further research is being done every year on caffeine shampoos, and it is possible to find many reviews across the internet which claim caffeine shampoos have a positive effect on hair loss. Despite this, it is important to take these reviews with a pinch of salt. Some people may be experiencing a placebo effect, whereby simply using the shampoo gives them greater self-confidence when looking in the mirror. Lastly, it is important to bear in mind that some types of hair loss come and go, and so in some cases, experiencing regrowth after using a caffeine shampoo may simply be a coincidence.

Does Caffeine Cause Hair Loss
The coffee bean has never been fought over like spices. In the 17th century, wars were fought and many people killed over simple spices we take for granted today.
It is believed that the properties of coffee were discovered long ago by an Ethiopian farmer, who after seeing how it affected his sheep, decided to try it himself. Ever since then, coffee has spread like wildfire around the globe, with coffee shops on practically every corner. People need their fix, and caffeinated beverages are the perfect pick-me-up for a dull day or a needed blast of energy.
The debate on whether caffeine causes hair loss is based on the notion that caffeine dehydrates the body, including the scalp and hair. Although there is some truth in this, evidenced by the frequent trips to the bathroom, it is not as bad as people make it out to be. A recent study found no evidence of dehydration with moderate daily coffee intake. By studying various blood and urine markers for dehydration, the researchers concluded that previous evidence of the dehydrating effects of caffeine need to be re-evaluated. Of course, this evidence only highlights that moderate use is completely safe, and will not affect the hair. It is possible that habitual, heavy caffeine drinkers could be at risk for dehydration.

Do You Really Need To Cut Down On Caffeine
Caffeine is the most consumed psychoactive drug in the world, and it’s probably harming your hair health. But don’t panic. The reason caffeine causes hair loss isn’t that it damages your hair follicles. It’s because caffeine interferes with how well you sleep, and that can cause some serious problems.
When you’re getting a good night’s sleep, your body can produce a hormone called melatonin that tells your brain to turn off the production of cortisol
This stress hormone also has essential functions in regulating your moods and hormones. Cortisol is terrible news for those follicles, so no wonder they start to dry out and break down.
If you’re a coffee drinker, you’ve probably wondered whether caffeine causes hair loss. In the past, it was believed that caffeine could accelerate hair loss. However, recent studies suggest that there’s no link between caffeine and hair loss.
Why Are Your Adrenals Important
Your adrenals signal the fight or flight response, which is your bodys response to stress. Fight or flight causes the adrenals to release cortisol and adrenaline. Cortisol is a hormone released by the adrenals for use in the regulation of blood pressure. In response to stress, the adrenals release greater amounts of cortisol.
Theyre pretty darn important to overall health and unfortunately we dont realize that our lifestyle choices and habits can have a detrimental impact on our adrenals. When we dont nourish and protect our adrenals, it can lead to a slew of health issues, negatively impact thyroid hormone production and slow the metabolism.

Does Caffeine Shampoo Work For Hair Loss
In short, no. There is not enough clinically viable evidence to support caffeine shampoo alone as an effective hair loss treatment. But thats not to say it has no use when it comes to maintaining and supporting hair growth.
There are studies that support the claim that caffeine shampoos can thicken hair, like this one from 2012 on the role of caffeine in the management of androgenetic alopecia, and another from 2010 on the use of caffeine for the same condition, and there is some evidence to suggest that topical caffeine can be helpful in reducing dihydrotestosterone the hormone which causes male pattern baldness.
Its worth noting that these studies are largely lab-based and would need more reviewing in a larger controlled clinical trial conducted with actual patients.
The good news is, however, that caffeine shampoo has been found to cause no harm and can help improve the health of the scalp, which in turn supports healthy hair growth when paired with a clinically proven treatment.
Would Caffeine Work For All Hair
As with mostly everything, caffeine works with different efficacies for everyone. A largely identical group of scientists performed an additional study, this time on both, female and male hair follicles. Female hair follicles exhibited greater perception and therefore better effects of caffeine on hair growth . having said that, caffeine treatment in both, males and females, continue to show promising results in helping with hair loss and improving hair growth.

Can Coffee Cause Hair Loss
Before you pour your daily cup of coffee down the drain, don’t worry. There’s no medical evidence that connects coffee and hair loss.
Now, don’t get us wrong here, because we’re not saying that coffee has no negative impact on our bodies â we’ve all had those days where that extra cup of java left us jittery, irritable and gave us insomnia when we desperately needed a good night’s sleep.
When it comes to hair loss, though, coffee is super low on the list of concerns.
While your regular cup of Joe wouldn’t be cause for concern, excess caffeine in your system could indirectly be a contributing factor in your hair loss.
If you’re drinking a lot of coffee, the caffeine could be boosting your stress levels and leaving you with poor sleep quality, which can both lead to hair loss.
With that being said, there are actually ways that coffee can help promote hair growth.
Will Drinking Coffee Help My Hair Grow
This study shows that topical caffeine application can stimulate hair growth not caffeine consumption.
Drinking coffee may have an effect on hair growth but this hasnt yet been proven. In any case, you would need to consume an unsafe amount of coffee before you drank enough to see visibly improved hair growth. So its not possible to reverse the effects of pattern balding by drinking coffee alone.
Coffee hair rinses have also been touted as a natural way to stimulate hair growth. A coffee rinse involves brewing and cooling coffee, then applying it to your scalp and the lengths of your hair while its still wet after washing. However, theres no firm evidence to confirm that coffee rinses genuinely stimulate hair growth. Coffee is also sometimes used as a hair dye, so you should avoid this method if you dont want to stain your hair.

How Does Caffeine Work With Hair Follicles
One in-vitro by University of Lübeck in Germany studied samples from patients suffering from androgenetic alopecia . AGA is a common form of hair loss amongst men and women. Samples were cultivated with different concentrations of testosterone and/or caffeine for a period of 120-192 hours.
Fischer, Hipler and Elsner, the leading scientists of the study, took the biopsies of hair follicles from 14 male patients, ranging in age from 20 45. Each patient was at various stages of hair loss. Firstly, they treated cultivated hair follicles with various levels of testosterone, which, unsurprisingly, resulted in slowing down of the hair growth. And afterwards they treated the same hair follicles with various caffeine levels, against a control group.
The results of this experiment had shown, that not only caffeine cancelled out negative effects of testosterone on hair growth, but also caffeine alone when applied to a hair follicle which was not pre-treated with testosterone had lead to improvement in hair growth.
In Vivo Penetration Studies
Transfer of the promising effects of caffeine on the hair follicle in vitro to an in vivo setting requires that caffeine can reach the desired target tissue. In the case of hair loss, the target can be either the hair bulb or the outer root sheath under the skin surface. However, one important function of the skin is to protect the organism from potentially harmful exogenous substances by acting as a barrier. Therefore, entering the underlying skin compartments is not trivial for most substances. On the other hand, caffeine is a model substance for skin barrier penetration studies , as it penetrates well into human skin, resulting in an ample bioavailability of caffeine after topical application on scalp skin.
Several analytic tools are available to determine the in vivo penetration of substances into the different layers of the skin. These include invasive and semi-invasive methods such as tape stripping , dermal microdialysis , and the detection of substances in blood samples . In vivo laser scanning microscopy can also be employed to investigate skin penetration properties. LSM is a noninvasive imaging method that can detect fluorescent reporter molecules in the skin up to a depth of 200 m . For the investigation of topical treatments, the penetration of these fluorescent reporter molecules, which are added to the topically applied formulation as a marker molecule, reflect the penetration properties of the formulation .

Some Common Myths About Hair Loss
Several myths are flying around about hair care and hair loss. Here we have dispelled some of them.
Shampoo causes or makes hair fall worse: many rumors are flying around that shampoos can cause or worsen hair loss however, after much research, there is no evidence, at least for now, to back those claims.
Baldness is gender-based: Another myth about hair loss that has been popularized is that baldness is only peculiar to the male gender. However, this is not true as anyone, regardless of gender, can suffer from baldness.
Too many Carbohydrates cause hair loss: Consuming a balanced diet is essential for maintaining healthy hair. No scientific research has linked high carb intake to hair loss. Carbohydrates contain nutrients that make the hair strong and healthy.
Can Caffeine Assist In Hair Growth
So caffeine and hair: Isnt that the best way to solve all of your hair loss problems? Not so quickly. A lot of people think studies are great. Can you drink a cup of green tea every hour and have a full head of hair in six months? The answer isnt.
Green tea, for example, has been shown to have a lot of potential benefits for the health of your hair, but these studies are still very early in the field, and they dont argue for a certain amount of caffeine or how it should be delivered.
This isnt what we have, though. Instead, we have a lot of research that says potential. Green tea, for example, has been shown to cut down on oil production in the scalp, stop dandruff, and soften the hair follicle in a review 2019. There was no direct link between caffeine and that, though it did play a role in other things.
One 2019 article discussed a study that found that applying caffeine to the skin to treat androgenic alopecia was linked to caffeines ability to shield mens barrier function. It also talked about lab studies that show that caffeine can make hair grow.
