blockage of hair follicles leading to inflammation and cysts
Follicular occlusion refers to the blockage of hair follicles, which can lead to inflammation and the formation of painful lumps or cysts. This condition is often associated with skin disorders like acne, hidradenitis suppurativa, and dissecting cellulitis, where the normal process of hair growth and shedding is disrupted, causing trapped hair and debris to accumulate within the follicle.
