hmmmm, I may have to give this a go, @Blossom1961 - my nails have never been particularly 'hard' - but in the last month, just playing my ukulele has busted them off down to my fingertip (and they were never particularly long beforehand either!)
I am wondering if my tablet is somehow causing them to splinter more readily - as I've had 8 years of uke strumming without a problem! 4 months of AIs & they are splitting & ripping off! :(
Earlier, I tried Hard As Nails but it didn't seem to help much. I even put some false nails on my strumming fingernails - but one went flying off, never to be seen again, during a song - so won't do that again! LOL And the glue isn't good for the original nail, either! :(
So you just eat jelly to get your 'dose'? It isn't painted on the nails & soaked in? (I hope that isn't a silly question!)
