I was shocked how quickly this product worked. I have had a split nail for maybe a year now, where the split goes slightly into the nail bed. Very painful when it gets snagged and never seemed to heal all the way. I did only a couple applications of this salve directly to the split and I could see/feel a noticeable difference! I applied it randomly when it looked dry and it’s now completely healed (span of 1 month)! I imagine it would have healed even quicker with consistent application. I’m not gonna credit my body with doing the heavy lifting of healing here because I’m currently in the first trimester of pregnancy and can’t keep anything down and the rest of my skin/hair is a wreck. Great salve, highly recommend!
