I have recently been using - Virgin Coconut Oil". My eyebrows have been falling out, also, whilst I have very strong and long finger nails, the cuticles and sides of my fingers (gardening without gloves !) get very dry and cracked. So far the coconut has been helping both. Further questioning has told me that it is very good for nails, skin, hair etc, and harmless. Perhaps rubbing coconut oil will help your poor, sore nails. regards, Mrs Bouquet
