Were talking about this on another thread somewhere, as I was getting vertical ridges on my nails and they were splitting [always had very strong nails]. Started using Protect and Perfect nail cream and, a couple of weeks later, it seems to be working. Also, if you buy one of those nail files in three sections and you buff your nails with the more abrasive section it gets rid of the grooves [sorry; does that make sense?]. I found that the Body Shop one worked better than the Boots one. In fact, The Body Shop sell a cream which is a lot cheaper than Protect and Perfect as well. I went there when I was 'got' by one of those people in a shopping centre that grab your hand, put some cream on, rub your hand and then buff your nails, then try to sell you a very expensive hand care package.[very naughty, because if you put cream on and rub your hands, they do look nice, cause all the old lady veiny appearance goes, temporarily]. I went straight to The Body Shop and they sold me the same stuff for a fraction of the price.
