Which condition would result in little or no sweating?

Anhidrosis is the condition that results in little or no sweating. It is characterized by the inability to sweat normally, which can lead to overheating of the body since sweating is a primary mechanism for regulating body temperature. Individuals with anhidrosis may find it difficult to cool down during physical activity or in hot environments, which can pose serious health risks, such as heat exhaustion or heat stroke.

Understanding this condition is crucial for cosmetology professionals, as they may encounter clients who have anhidrosis and may need to consider this in product selection, service offerings, and preventative advice regarding skin and hair health. In contrast, hyperhidrosis, dermatitis, and psoriasis are associated with increased sweating, skin inflammation, or skin conditions that could affect sweating but do not directly lead to its absence.
