What should be done to maintain the shape of a finger wave during drying?

To maintain the shape of a finger wave during the drying process, covering the hair with a hairnet is an effective method. A hairnet provides gentle support, helping to keep the carefully crafted shape secure while allowing it to dry. This prevents movement of the hair that could distort the waves, preserving the style.

Using a hairnet also enhances airflow and allows for even drying, which is essential for ensuring the integrity of the wave pattern. It creates a barrier that maintains the placement of the curls without the weight of other products or the potential for them to fall out of position due to gravity or environmental factors.
