Detailed answer

Dermatographism is a type of hives that occurs due to excessive dryness and sensitivity of the skin. When the skin becomes dry, it can develop cracks and flakiness, which can trigger an immune response. Scratching or rubbing the skin in this condition can cause the release of histamine, resulting in the appearance of hives. Keeping the skin adequately moisturized is essential in managing dryness and reducing the risk of developing dermatographism hives.
