Patchy hair describes a condition where hair growth is uneven or irregular, and can be either localized or affect the entire scalp. This can manifest as bald patches, thin or empty areas, or areas with significantly less hair growth than surrounding regions.
Patchy hair can have various causes, including genetics, hormonal changes, medical conditions, nutritional deficiencies, and styling practices. It is a prevalent hair concern that affects people of all ages and genders.
