Air-drying can be a low-effort styling option, though the result will vary with hair texture, length and the weather. The goal is a routine that leaves your hair manageable and comfortable.
Prepare gently
After washing, blot excess water with a soft towel rather than rubbing vigorously. Detangle gently in sections using a method that suits your texture, and distribute any leave-in product in a small amount through the lengths.
Adjust as it dries
Try a loose part or gently shape curls while damp. Avoid tying very wet hair tightly. If your hair takes a long time to dry, a dryer on a low setting may suit you better; there is no single method everyone must follow.
Consider the forecast
Drying time can change with humidity and temperature. If you need to leave while hair is damp, choose a comfortable loose style and allow enough time for it to dry rather than pulling it tightly into place.
