An anonymous reader from California shared this solution for split fingers:
You can prevent split fingers by taking Evening Primrose oil every day. I take 6 softgels of UltaPrim made by Natural Factors a day, 2×3 times a day, and as long as I don’t forget to take a dose I don’t have a problem, but if I forget I will probably have a split finger the next day. I’m a window washer and I’ve tried all sorts of lotions and creams and they don’t work because it’s what goes into your body that counts not what you put on your fingers. This works.
