My nails have always been weak but they are worse now. I couldn't decide if it was another side effect of medication. I've been filing them regularly and keeping them low in the hope they will grown stronger. Also order stick on nails to try x

My nails have become very weak and a couple of them have begun to spoon and bend under ...more calcium, magnesium and iron required...try hair, skin and nails supplement...they are readily available in supermarkets etc xx

I have the opposite situation--extremely hard nails that grow rather quick. This has been the case my entire life but I think it has to do with having keratosis pilaris (buildup of keratin in hair folicles causing patches of small bumps--but keratin is also the main component of hair and nails). Maybe I'm lucky I've had those little bumps everywhere and it's saved me from similar nail issues! Good luck to you all! :)
