I have a natural nail client in her early 30s who has pitted nails. What causes this condition and what can I do to help?

The most common cause of pitted nails is nail psoriasis. Other conditions, such as trauma, may cause pitted nails, but they are very rare. Ask your client if she has a family history of psoriasis or whether she has any skin lesions, which could be due to psoriasis. If the pitting is extensive or if the client says there is a history of psoriasis, then I would recommend she see a dermatologist because there are a number of treatments that can help pitted nails and/or nail psoriasis. In the meantime, be very gentle when manicuring her nails.
