Sometimes an itchy scalp can be due to problems that also cause the hair to fall out. Hair loss is a serious and troublesome problem. There are a variety of conditions that can lead to hair loss. Some hair loss that is accompanied by an itchy scalp may not necessarily be permanent hair loss. The hair may grow back once the problem is corrected. Some of these conditions are ringworm, folliculitis, seborrheic dermatitis, and psoriasis.
Ringworm can be found on various parts of the body including the scalp. Ringworm comes from a fungal infection. Symptoms include itchy red patches and hair loss. It is generally quite itchy. It can form scales and peel. If ringworm is not treated is can spread and become worse. It is also contagious.
Folliculitis occurs when the hair follicle becomes blocked and infected. Pimples and sometimes even boils are signs of folliculitis. When this condition is severe it can lead to scaring and hair loss.
Seborrheic dermatitis can also cause the scalp to itch and may lead to hair loss. The condition includes extreme itching and inflamed and flaky scalp. These flakes may form greasy scales and mounds of flakes on the scalp. Hair may fall out in the worse patches but will generally grow back once the condition is cleared.
Psoriasis is another condition that is often found on the scalp. It is not a contagious condition, but is often on other parts of the body as well. This itchy condition shows white flaky patches. It is itchy and may cause temporary bald spots to appear.
