Nails Growing Bent Downwards

Patient: I am 27 and for about 15 years I have had itching all over my body and due to excessive scratching over the years I believe my nails grow bent downward from the nail bed. When I touch my nails I can feel the nail bed itself is uneven (wavy).Can you recommend any treatment for them to grow straight.My itching has stopped which was due to imbalanced hormones causing irregular periods. I take Diane 35 tablets to get regular periods.
