I was wondering whether the IBX treatments I've seen at my local salon do what they say? I have weak, bendy nails which tear and have tried all sorts to strengthen them before with no effect ( various Sally Hansen products, Nail Envy, to name a couple). IBX seems to penetrate the nail from reading about it, so might be better? Diet is fine and varied, I wasn't sure if those hair and nail supplements are any good either. My hair is great and in good condition, so I suspect it's just a hereditary thing. Is there anything out there to help?
