Bald patches or circular hair loss
Overview
Bald patches or circular hair loss refers to distinct round or oval areas of the scalp where hair has fallen out, leaving smooth, hairless spots. This patchy hair loss pattern typically creates well-defined circular or irregular shaped areas of baldness that contrast with surrounding normal hair growth.
Common Causes
Hair loss in circular patches can occur due to autoimmune conditions where the body's immune system mistakenly attacks hair follicles. Stress, hormonal changes, and certain medications can also trigger this type of hair loss. Nutritional deficiencies, particularly iron or protein, may contribute to patchy hair loss patterns. Some people may experience this after illness, major life changes, or due to genetic predisposition.
Severity Levels
Mild: Small, single bald patches that may be barely noticeable and could be mistaken for normal hair thinning. The affected area is typically less than the size of a coin and may show signs of early regrowth.
Moderate: Multiple bald patches or larger circular areas that are clearly visible and may affect your appearance or confidence. The patches are well-defined and may be spreading to new areas of the scalp.
Severe: Extensive hair loss with numerous large patches, significant scalp involvement, or progression to near-complete baldness. This level typically causes considerable distress and may impact daily activities or social interactions.
Medical Attention
Seek medical attention if you notice sudden onset of circular bald patches, especially if they're spreading rapidly or accompanied by itching, burning, or skin changes. Consult a healthcare provider if the hair loss is affecting your quality of life or if you have multiple patches appearing. Early evaluation is recommended as some causes of patchy hair loss respond better to treatment when caught early.
