ok this might seem like a silly question to some people but i dont know the answer so that is why im asking k :)
nails are made of keratin right? and keratin makes the nail grow im talking about finger nails here! i used to bite my nails now i grow them but they grow so fast! anyways my nails are now really long and one of them has broken like a crack so my question is if i dont cut it off will it join together again? i dunno if this makes sense to anyone, last time this happened i just bit them off but one month later its really long again and i dont wanna to cut it off cos i'll end up biting the rest of my nails so yea my question is cracked nails do they join together again?
