Solid nails with salt water
On vacation by the sea (saltwater) I always had firm nails - that's what I wanted at home.
What was it? We had always vacationed by the sea and I swam in it almost every day. After a few days, the nails were firm and did not peel like paper (as usual).
Now every other day I bathe my nails in some salt water (taste: it should be as salty as sea water), dry them off easily and my nails are healthy and strong. Also, I have no problems with redness and inflammation of the nail beds more.
