There are various forms, including atopic dermatitis, which is the most common type of eczema.Fungal infections: These are common and sometimes involve the skin, nails, and hair. A group of yeasts called Candida can cause a wide range of fungal infections, including oral thrush, ringworm, athlete’s foot, and balanitis.Hair loss: About 80 million people in the U.S. have hereditary hair loss. A range of health issues can also cause hair loss, including head lice, which affects around 6–12 million children aged 3–11 years in the U.S. annually.Warts: These are contagious, benign skin growths that appear when a virus has infected the top layer of skin.
