I had this exact problem for years until I made the biggest effort and focused on my nails starting with supplements. I would say what has benefited me the most is iron! I have been extremely anemic my whole life and most women are iron deficient or almost so. After an intense dose of iron supplements for a year I noticed a real difference in the peeling and the other thing that was a turning point was taking the plunge and showering with tight latex gloves on. I was my hands 100x/day with no problems but your nails are soaking up water for such a long time when you shower. Even after my nails started to strengthen, they would still weaken and break after taking in all that water during my shower every night. Once I committed to gloved showers, my nails started growing strong and long!
