Which supplements work best?And do finger nails stop growing at a certain length?

There's nothing you can do to make them grow faster, and as for strength, just nail care like filing trimming, oils, polishes and stuff like that can make them strong. As for length. Nope, they just keep growing non stop. There are people in the guinness book that have disgustingly long finger nails that have gotten all brown and cracked and so long that they curl up into giant rolls of disgusting brown whateverthefuck. ( link ) So no there is no end to how long they get, but there should be a limit set.1
