Velcro rollers should be used on which type of hair?

Velcro rollers are designed to create volume and curls in the hair. The optimal use of Velcro rollers is when the hair is dry. This is because dry hair has more natural elasticity and can hold the shape created by the roller more effectively. When rollers are applied to dry hair, the hair's cuticle lies flat, allowing for better grip.

Using Velcro rollers on wet hair may prevent them from functioning properly, as wet hair can be heavy and may not hold the roller's shape well as it dries. Additionally, rolling wet hair can lead to longer drying times and possible frizz, affecting the end result.

Although curly hair, color-treated hair, and wet hair can benefit from certain styling techniques, for Velcro rollers specifically, dry hair ensures the best outcome for achieving volume and defined curls.
