I’m wondering whether my T2 diabetes causes my brittle, flaky nails. Does anyone know? I’ve had this problem for years now, and have tried just about everything to solve it. I should have bought shares in Sally Hansen and Boots because if it’s on the market, I’ve tried it. And nothing works. I stopped using the paint on strengtheners because they didn’t do the job, and I thought massaging in oil, cream etc etc would be more effective. I’m not aiming for talons- just tidy non scrubby hands would be fine. They look so tatty.
