What is the recommended distance for holding a hair dryer from the hair?

Holding a hair dryer 6 to 8 inches away from the hair is recommended to ensure an even distribution of heat while minimizing the risk of damage to the hair. This distance allows for effective drying without concentrated heat that could lead to dryness or scorching, which can occur if the dryer is held too close. Additionally, maintaining this recommended distance helps to protect the scalp from overheating, thereby preventing irritation.

Using a distance beyond 8 inches may result in less efficient drying, potentially requiring more time and increased exposure to the heat. In contrast, positioning the dryer under 6 inches could increase the likelihood of causing harm to the hair and scalp, making 6 to 8 inches the optimal choice for safe and effective hair drying.
