1. Yellow Nails

Nails acquire a yellow discolouration by constant use of nail polish. If the condition persists even after limiting nail polish use, consult an expert. It may be an indication of certain lung diseases or rheumathoid arthritis. Smoking also causes this condition to worsen.

5. Washboard Nails

Thumbs sometimes have grooves and ridges at its centre. It makes it look like a washboard. This is probably nothing to worry about since it forms when the cuticle on your thumbs usually gets pushed back. Breaking this habit revives the normal texture of nails.
