What is the cause of empty toenail caps?

Toenail cap inside is empty, is a symptom of nail stripping, most of them are caused by external forces, but also some people are due to onychomycosis or chronic skin diseases.
1. After being hit or squeezed by external force at the toenail, bruises are easy to form under the toenail, and heavy manual laborers or people who love to wear high heels are prone to have them. Bruising under the nail cannot flow out normally and takes five to six months to drain out of the body as the nail grows. The blood stays between the toenail and the skin, causing the toenail to peel away from the skin.
2. Onychomycosis is caused by a fungal infection, usually caused by a fungus on the foot that spreads to the underside of the toenail. Ringworm can cause the toenail to twist and distort, causing the toenail to detach from the skin underneath the nail and form nail peeling.
3. Some of the chronic skin diseases such as eczema, psoriasis or lichen planus occurring in the toenail, due to local inflammation may damage the nail bed, resulting in deformed growth of the toenail, which can lead to the symptoms of toenail peeling.
Hollow toenail cover need to go to the hospital in time, under the guidance of the doctor to choose the appropriate treatment plan.
