What to use if I lost my nail?

If there is no wound or hematoma in the place of nail loss, it does not pose a threat and you can function normally. It should be borne in mind that it can be very tender and more susceptible to fungal infections. Therefore, it is recommended to use disinfectants, such as octenisept/oktaseptal: https://www.gdziepolek.pl/produkty/87829/octenisept-aerozol-aerozol/apteki https://www.gdziepolek.pl/produkty/97727/oktaseptal-aerozol/apteki In addition, in podology stores you can buy Onygen cream, which stimulates the regrowth of the natural nail plate. Unfortunately, this product is not available in pharmacies. It is worth considering a visit to a podiatrist who, depending on the condition of the place, will properly clean the placenta, apply therapeutic agents and indicate how to properly care for this place at home. It is also possible to perform nail reconstruction that imitates the natural nail and protects the placenta from injuries and mycosis.
