Caffeine shampoo is a cosmetic product intended for hair cleansing whose composition is enriched with caffeine.
Caffeine is a purine-based alkaloid of natural origin contained in various plants, such as coffee, tea, cocoa, guarana and maté.
It is a molecule which - when taken orally - is capable of exerting an "exciting action on the central nervous system and a" vasoconstrictor activity. At the same time, caffeine - used externally - is also attributed anti-edema properties, the ability to promote lipolysis and the ability to promote hair growth.

from male patients with androgenetic alopecia. Research has shown that caffeine is able to stimulate hair growth in vitro, while reducing testosterone-induced suppression of hair follicle vitality. In fact, this hormone and even more its dihydrotestosterone derivative are involved in androgenetic alopecia.
The second study, on the other hand, was conducted in 2014 by taking hair follicles from male and female subjects, subsequently grown in the laboratory and subjected to various tests to evaluate the efficacy of the molecule in question. From this study it was observed that caffeine to which laboratory grown follicles were exposed:
- Prolonged the anagen phase of the hair follicle (growth phase);
- It favored the lengthening of the hair shaft;
- It stimulated keratinocytic proliferation on the hair matrix.
This study also showed that the follicles taken from female individuals were more sensitive to caffeine than those taken from male individuals.

However, despite the results that appear to be very encouraging, it should be emphasized that such studies have been conducted in vitro and not in vivo and most importantly, they were made using pure caffeine and not a caffeine shampoo.
However, another more recent study ** was conducted in vivo, on female volunteers, using a real caffeine shampoo. One part of the volunteers used a shampoo containing this alkaloid, while the other part used a control shampoo without the molecule in question.
The results were measured by carrying out a hair pulling test after 6 months of using the two cleansing products. The study showed that the amount of hair lost during the pull test by women who used caffeine shampoo was significantly less than in women who used control shampoo.
This study, therefore, seems to confirm the effectiveness of the caffeine shampoo. However, despite the potentially promising results, it is good not to get too enthusiastic. In fact, in order to scientifically demonstrate the real effectiveness of caffeine shampoos, it is necessary to conduct further and more in-depth research in vivo and, in particular, on volunteers with and without androgenetic alopecia. Only in this way will it be possible to determine if caffeine shampoo can be really useful in combating hair loss and in what concentration this molecule must be present to guarantee the desired effect without causing problems or unwanted effects.
