A study from the University of Pennsylvania showed that while the rest of the hands contained between a hundred and a thousand bacteria, in the areas under the nails there were thousands and thousands of bacteria for each finger. The reason why bacteria would multiply so much in this area would be that here a perfect environment is created for them to proliferate: on the one hand, it is protected by the nail and on the other, the humidity would remain trapped there.
Washing your hands is not enough to eliminate dirt and bacteria that accumulate under the nails and it is necessary to resort to the use of a nail brush to remove them. However, Dr. Román Miñano, a dermatologist at the Institute of Integral Dermatology, affirms that it is not necessary to use the brush every time we wash our hands since that would cause them to suffer and weaken over time. It would be enough to use it when we seek a more in-depth cleaning, for example, before handling food or healing any wound.
WHICH BRUSH IS BEST?
Both those with nylon bristles and natural bristles are a good option as there is no difference when it comes to hygiene. As for the hardness of the bristles, it will have to be chosen depending on whether our nails are hard or on the contrary, they are brittle and soft.

THE NAILS, BETTER SHORT
Short and filed nails harbor less dirt and bacteria than long nails, since it is easier to access dirt using a brush or other hygiene and care utensil (file, scissors, orange stick, etc.). For the same reason, using false nails will make it easier for bacteria to accumulate under them.
