Hi there. Regular manicures should help quite a bit. One a week should do. Also, nutrition of course. You can read up on Fish Oil and other Supplements to aide in nail growth.
You can do your own manicures at home.
1. Soak nails after you remove all polish in dove detergent or something gentle for a few minutes to soften cuticles.
3. Massage a nice Vitamin E or Cocoa Butter lotion into cuticles.
4. Gently push cuticles back with an orange wood stick or damp Q tip would also work. (wipe off excess)
5. File edges of nails gently and in long sweeping motions left then right....not back and forth. Back and forth breaks weakens the nails.
6. Polish as usual.
