Potential benefits of caffeine shampoo

- Nourishes both hair and hair follicle.
- Stimulates hair growth.
- Exfoliate your scalp.

What do the studies say?
There is little research in favor of it. A 2007 study found that washing your hair with a caffeine-containing shampoo can stimulate hair growth. In this sense, this substance is believed to help block the effects of dihydrotestosterone (DHT) in the follicle.
Other study reached similar conclusions; caffeine can lengthen the shaft, even if the hair follicle has been exposed to testosterone. However, unlike the first study, which was done with a group of volunteer subjects, in this case the evidence was obtained in the laboratory.
In a experimental research Chest shampoo with caffeine was applied to two groups of people. He was washed after two minutes and blood samples were taken at 72-hour intervals. in both groups it has been found that caffeine can be absorbed through the follicles.
However, most of the studies have been done in the laboratory or with just a few people involved. Therefore, more long-term controlled clinical trials, in larger groups, are needed to draw definitive conclusions.
Possible side effects
For now, there are few noticeable side effects of caffeine shampoo. There may be some risk of transient irritation on the scalp, especially in people sensitive to any of the ingredients contained in the product.
This is more common in commercial brands than in homemade preparations. The reason? Some use synthetic preservatives, such as methylparaben, propylparaben and phenoxyethanol. Second researchthese ingredients can cause scalp irritation and allergic reactions such as itching, redness and a burning sensation.
On the other hand, there are those who warn that despite continued use, the hair continues to thin. And although many claim to have benefits, in others the effectiveness is quite small. Even with prolonged use of caffeine shampoos, the results may become less noticeable.
Despite the years that some brands have been on the market, the effectiveness of shampoo with caffeine in terms of halting the progression of alopecia has not yet been fully demonstrated. Some research points weakly to saying yes. Until more studies are done, one cannot make a statement, let alone generalize.
So far it is known that caffeine molecules penetrate the hair follicles. But from there to believe that this is the cure for baldness, there is still a distance. What is warned is that some may have allergic reactions with its use. In this case, rinse thoroughly with water and discontinue use.
So, if you’re starting to show signs of alopecia and if you’ve been thinking about trying a shampoo with caffeine, you can, but with caution. Preferably, consult a dermatologist to find out if any of the ingredients can cause irritation.
In the early stages of baldness, caffeine-containing shampoo can have an additional effect if it is combined with other more proven treatments, such as minoxidil or finasteride. It’s not very likely that it alone could make such a significant difference.
