So stay with us for this one, cos it sounds bizarre. Simply peel and finely chop a clove of garlic and then...add it to a bottle of clear nail polish...and let it stew for a week.
Seriously, you will have nails that are as hard as, well, er, nails! You can send your thanks to the nail-lovin’ folk of The Dominican Republic.
Be warned: the initial smell is dubious (aka violent), but it quickly wears off and you will be left with talons of steel! The lengths we’ll go to for beauty eh?
