Many thanks for all the great "science" info - i agree re with the " feeding our nails from the inside out" theory and also that a strengthener would be useless - if the nail is peeling its dehydrated so a treatment such as "LD Hydra-flex seum" would be ideal. Ms Trouble is so right re putting our hands and nails constantly into water(particulary with detergent) and also how medications etc can affect our hair/nails. The only other thing i would want to suggest is using Leighton Denny's Crystal Nail File - using an normal emery board, if not used correctly,will cause peeling nails but you can use the crystal/glass files in any direction without damage - imo Leightons is the best on the market just now. My last tip would be to keep your nails short for a while to allow them to recover and grow - as Ms Trouble has said it can take up to 6mths(results vary) from the nail to grow from the matrix to the free edge - the nail is "alive" at the matrix - the nail bed/free edge is dead therefore we are ideally wanting to encourage a full regrowth for the strength to return(and hopefully no peeling) - the same applies to hair growth.
Ms Trouble - thanks for the blast from the past - Nail Eat and Nail Drink from Supernails i remember a few years ago Debs Flint coming onto the boards to buy one of each from one of our forumites. I now rave about and use Nails inc "Victoria" but in the early days of QVC it was Supernails "Morticia" - remember their "little pot of magic" cuticle cream and "Armour" and "Anchor" base and topcoat?
