What is the cause of nail delamination?

There are two diseases that can lead to nail delamination. One is onychomycosis, commonly known as "onychomycosis". The other is nail stripping, mainly due to nail malnutrition. For psoriasis treatment, because the drug into the deck is difficult, and nail growth is slow, so the treatment is more difficult, the key is to adhere to the drug. First of all, use knife or file to remove the affected nail to the maximum extent, and then apply 30 acetic acid aqueous solution or 35 iodine tincture twice a day for 36 months until the new nail is formed; severe cases can be combined with oral antifungal drugs. For exfoliative onychia, attention should be paid to supplementing calcium, vitamins and trace elements.
