What is nail psoriasis? - If you have skin psoriasis, there is an increased risk that you will also experience nail problems. Fingernails are more commonly affected than toenails.
Psoriatic nails can present as small pits in the nail plate, or as being thickened and deformed. The nails are often yellow and can have a white or yellow margin at the tip of the nails because they are separated from the underlying skin, which is called onycholysis.
Keep a basic nail care routine
Nail psoriasis is rather difficult to treat, and it is therefore generally advisable to consider also to focus on your basic nail care. This includes keeping the nails short and trimmed to the point of firm attachment, and to protect the nails when you do anything that could cause damage to them, for instance by wearing gloves.
