Your nails are delicate, and scrubbing them too roughly can actually expose you to infection.
Another no-no: Using metal nail tools under the nail, as too much digging under the nail plate will cause it to separate from the skin, leading to an irregular white arching nail tip .
Before you do anything, it’s important to make sure your nails and the skin around them are thoroughly dirt-free. My Nails Clinic recommends applying soap to a toothbrush, then gently scrubbing your nails and skin. This will remove dirt and exfoliate any dead skin without the need for harsh, drying chemicals or expensive scrubs.
