It’s well understood at this point that testosterone, the male sex hormone, plays a role in genetic hair loss. As such, the researchers expected the hair follicles cultivated within the testosterone to show poor hair shaft growth. Perhaps the most convincing study on the topic was published in 2007 by researchers from Friedrich-Schiller-University in Germany ( 1). There are three major phases of the hair growth cycle: anagen (active growth), catagen (transition), and telogen (rest). For this reason, the UK Advertising Standards Authority ruled that Alpecin could not advertise products as reducing hair loss. They came under scrutiny for only using male patients in studies who suffered from androgenic alopecia and for using unorthodox measuring practices. Some studies also did not have control groups for comparison.

There are also quite a few ingredients that you may have seen present in other over-the-counter shampoos and cosmetics, such as the detergent and surfactant Sodium Laureth Sulfate (SLES). When it comes to vascular effects, caffeine is a vasoconstrictor ( 8). The stimulant narrows the blood vessels which increases blood pressure and may increase the risk of coronary artery disease. I’ll also look at the research which supports caffeine use for men and women with pattern hair loss. This can help you to decide whether caffeine is really as powerful as many people claim. Those results are when the researchers used the Per-Protocol (PP) analysis, which does create some bias ( 5).

In this post, I’ll introduce the caffeine-based hair care brand Alpecin. This will include an introduction to its products, as well as a look at the product’s claimed benefits and ingredients.

It’s true that Alpecin products contain caffeine. But that’s not the only thing they contain. They also consist of preservatives and detergents that may strip your scalp of its natural oils and ultimately cause further irritation. Alpecin’s study was conducted using extracted human hair follicles, and performed in vitro (meaning outside of the body). This means the results of their research can’t necessarily be applied to real-world hair loss, as how hair follicles react on your head is very different to how they react in a Petri dish.This has been documented numerous times, and its issues have even resulted in other brands (such as Rogaine) creating an alternative product without it present. Minoxidil has been proven effective at growing hair in men and women with AGA. However, there are some side effects associated with its use and many people prefer to take a natural approach to hair growth. Are you embracing grey hair? And want to maintain it, all the while combating baldness? This Power Grey combination is tailor-made to enhance naturally older hair while protecting it. Because caffeine is a stimulant, there is a possibility of side effects even when it’s applied topically. NOTE: This section takes a general look at the side effects that may occur as a result of using caffeine shampoo. The side effects mentioned below are in no way attributed to Alpecin.

When exposed to testosterone, the male hair follicles were shown to have just 39 percent in anagen phase. The hair follicles retrieved from female scalps weren’t as affected with 59 percent in anagen phase. No Alpecin review would be complete without taking a look at what customers have to say about the brand and their product. So, we took to the internet to get the latest scoop and sleuth out all the nitty-gritty details. There are a few differences, though perhaps the most noticeable is the addition of propylene glycol in this formulation. There’s actually a growing body of research on caffeine’s benefits, and one of those is hair growth.

Are you worried about hair thinning? Caffeine shampoos like Alpecin aren’t always the best way to counteract hair loss, especially if you have coloured hair or a sensitive scalp. And given that the advertising for Alpecin shampoo states that: "over one million bottles have been sold" in the UK alone, this does confirm its popularity as a hair loss product, and also suggests that there do seem to be many satisfied customers. Conducted at the Center of Experimental and Applied Cutaneous Physiology and Clinical Research Center for Hair and Skin Science, Charité University Berlin, Germany. These preservatives can cause scalp irritation and lead to increased itching and redness. You may also suffer an allergic reaction to caffeine. Discolouration

As noted by the researchers, there was a three-day hair wash quarantine before visits three and four.But, given that coffee-junkies are not immune to hair loss, if caffeine does help, clearly you can't drink your way to a full head of hair! It must be applied topically within a suitable carrier to deliver it down into the hair follicles. There are a lot of claims that caffeine is an effective treatment for male pattern baldness – but is it fact or fiction? Some people have reported increased hair fall and thinning after using Alpecin products. A possible cause of this is the presence of synthetic preservatives. These include propylparaben, methylparaben, sodium citrate, and sodium chloride.
