idk about the nails but o’keeffe’s working hands cream was a godsend for me last winter

I had this problem when I was hired and I started taking collagen powder. I noticed my nails were getting stronger & thicker after about 2 weeks. I swear by it.

I use Weleda’s Hand lotion it’s super thick, you only need a dab

Try taking biotin supplements, use o’keefe’s like another partner said, and definitely invest in vitamin E i think it is, its Sally hansen vitamin E nail & cuticle oil, its not nail polish you just rub it on your nails and it strengthens them :)

I'd say just use a clear coat
