assistant
The most common causes of a stye include blocked follicles, bacteria, trauma to the area, and poor hygiene. Blocked follicles can occur when hair follicles become clogged with oil or dirt, preventing drainage. Bacteria can enter the follicle through open wounds or abrasions in the skin. Trauma to the area can cause swelling which can block the opening of the follicles. Poor hygiene can also increase the risk of developing a stye.
