Welcome back Lucy, we were missing u. Im not good at nail beauty, may be someone here has a better suggestion.
Anyway, limit the use of nail polish remover, this will dry-up and damage ur nails, if needed, look for acetone or alcohol free nail polish remover. apply some good moisturizers to cuticles and fingernails, for better result u may wear some protective gloves during night (this will help maintain the moisture to ur nails).This will help nail grow faster. Applying good normal clear nail polish might help maintain the moisture to the nails and help grow faster.
