👉 Cossura is a disease that affects the hair follicles, causing thinning or loss of hair on specific areas of the body. This condition can be both genetic and environmental, with some individuals inheriting the condition from their parents. It's often caused by an infection in the scalp, such as a fungal infection, or by hormonal changes that disrupt normal hair growth cycles. Cossura is characterized by thinning hair near the hair follicles on the face, chest, neck, and back
