First of all, eating quantities of gelatine cannot strengthen soft nails, nor can it encourage them to grow. However, some peoplle belive that kelp or seaweed supplements from health stores have an effect on both nails and thier relations in keratin, hair. Avoid soaking them in very hot water and detergents which dries nails out and causes the keratin layers to separate and peel.

Resign yourself to the fact that you cannot grow your nails to any great length. Keep them well-filed and shaped instead-the shorter they are the longer they are likely to stay intact. Reinforce them with a nail-strengthening product, or an extra-hard strengthening varnish.
