Unveiling Hidden Facts About Common Scalp Conditions

Problems with scalp health can lead to discomfort and self-consciousness. Discover some lesser-known scalp disorders that might surprise you.

Many scalp issues result in hair thinning, excessive shedding, or bald spots. While aging and genetics are typical causes of baldness, numerous scalp conditions can cause hair loss independently. Here are some common scalp diseases with their main characteristics.

Psoriasis

Psoriasis is a long-term condition featuring itchy, scaly, reddish patches on the scalp, which may cause hair loss in affected areas. It is thought to result from genetic predispositions and environmental triggers. These patches resemble severe burns and can be quite uncomfortable.

Alopecia Areata

This autoimmune disorder, often called 'spot baldness,' causes sudden patchy hair loss on the scalp and sometimes other areas of the body. The immune system mistakenly targets hair follicles, often with a hereditary component. Nails and skin ridges may also be affected.

Scalp Ringworm

Medically known as tinea capitis, scalp ringworm is a fungal infection common among children globally. It results in circular, scaly patches on the scalp with hair loss, itching, and inflammation. Fungi invade hair and skin tissues, producing these symptoms.

Head Lice

Head lice infestation is a widespread scalp problem that causes intense itching and scalp discomfort due to lice crawling and biting. Treatment typically involves medicated oils and topical solutions, but complete eradication may require time.

Hair Shaft Disorders

Conditions such as thickening or thinning of hair shafts (like trichorrhexis nodosa, monilethrix, pili torti) weaken hair strands, making them more prone to breakage. These abnormalities can significantly change hair appearance and texture.

Diffuse Hair Loss

Excessive hair shedding, or balding, often results from factors like telogen effluvium—where hair prematurely enters the resting phase due to stress or illness. Chronic cases may take years to recover and are linked to medical issues such as lupus or nutritional deficits. Lifestyle factors like stress, pollution, and poor diets also play roles.

Recognizing that many scalp issues are influenced by lifestyle choices underscores the importance of good hygiene and health. Persistent symptoms should prompt consultation with a dermatologist for appropriate treatment.
