How can a barber prevent hair breakage during blow-drying?

Using a heat protectant and appropriate techniques is essential for preventing hair breakage during blow-drying. Heat protectants create a barrier between the hair and the heat source, reducing thermal damage and moisture loss. This helps maintain the hair's integrity and strength. Additionally, employing proper techniques, such as keeping the blow dryer at an appropriate distance, using medium heat settings, and drying in sections, helps to minimize direct heat exposure and prevents overheating any single area of hair. This comprehensive approach ensures that hair remains healthy and less prone to breakage.

In contrast, using the highest heat setting can lead to excessive damage and dryness, while drying hair completely before styling can contribute to brittleness. Excessive use of a fine-tooth comb can cause mechanical breakage and weaken hair strands. Thus, the combination of a heat protectant and careful technique is the most effective method for safeguarding hair during blow-drying.
