Pseudopelade
Also known as alopecia cicatrisata, this is a rare condition that primarily affects women and sometimes children. Pseudopelade is an inflammation of the upper portion of the hair follicle, while alopecia areata’s inflammation occurs primarily around the lower part of the hair follicle. While alopecia areata can progress indefinitely, pseudopelade causes hair loss over several years and then stops, resulting in bald patches where the follicles have been damaged. Once the progression of hair loss stops, so does the inflammation in the upper portion of the hair follicle.
Scleroderma
An autoimmune disease, scleroderma is a gradual hardening and tightening of the skin that can also cause hair loss. As it progresses, the hardening can spread throughout the body to affect joints, muscles, and organs.
Tick Bites
When hair loss occurs In the area of a tick bite, it IS temporary. The hair will regrow when the inflammation subsides.
Lichen Planus
Most often seen In middle-aged adults, this condition produces pink papules on the skin and scalp. These papules have a shiny, smooth, Aat surface and can expand to form pink, violet, or brown plaques. The hair inside these plaques can be lost. Lichen planus can be confused with hair loss from systematic lupus in skin biopsies, so great care must be taken in making a diagnosis.
Psoriasis
Hair loss caused by psonasis can occur when the affected patches of skin have hair follicles that have been forced into the hair shedding phase.
