Nails! 😭

So, 3 weeks ago, I started using 'stop n grow' on my nails to stop my habit of biting my nails! I still occasionally use it, but I don't need to, because my habit has been broken. But I was just wondering, is there any way to grow my nails faster? Make them healthier and stronger? Like, is there a way I can strengthen them so they look better. Right now, they look crooked and the cuticles look bad! I really wanna get nicer nails so people don't laugh at them or look at the oddly! Thank you! 😊
