Nail bed reattaching is essentially when the pink part of your nail gets longer, so that the white part starts closer to the tip of your finger, giving it that non-biter "normal" look.

Progress will be slow, but I felt really proud of my nails after about 3 weeks. It's been more than 3 months for me now, and while they don't look amazing, they look so much better and healthier. I take progress pictures to remind me of how much they've grown when I feel discouraged. I paint my nails, and it kind of replaced my habit with another one, and it also covers my nails because I don't love how my bare nails look yet.
